"After years of trial and error, I built the system I wish I had from day one"

Hugo Rivera

Hugo Rivera

International best selling fitness author (2M books sold) & 37 years helping clients transform their bodies and  life.

My journey into fitness started like many others—full of confusion, frustration, and endless conflicting advice. I wanted to first simply go from Obese to Skinny but had no clue how to do it and ended up getting anorexic. Thanks to my concerned family that took me to a nutritionist that told me: "Food is not going to make you fat. Only the abuse of the wrong foods will!" With that said I committed to studying nutrition with the aid of my grandfather who was a Medical Doctor. After I stabilized my weight at a measly 95-lbs, a lady friend told me that I would look good if I gained a little bit of muscle. I asked my parents to get me a muscle building magazine so that I could start to learn bodybuilding. After seeing Arnold Schwarzenneger I was hooked!


While at first training under Arnold's routines worked for me (even though I was always excessively sore), I fell into a plateau that I could not overcome. I spent years trying every workout, diet, and supplement, only to find myself spinning my wheels and doubting if real results were even possible. It wasn’t until I committed to understanding the science behind training, nutrition, and recovery that everything changed for me. So I started using the scientific method to see what workout and diet combinatons worked and which ones didn't. By recognizing patterns I started to cycle my training in a way that would push my body for a few weeks with higher volume workouts, followed by a period of training with less volume but heavier weights. This was a huge breakthrough and in combination with all the new knowledge I had now accumulated on nutrition and supplements, gains started to come steadily!

As I began writing fitness books and coaching others, I realized most people struggle not because they lack motivation, but because they’re overwhelmed by information and don’t know where to start! I saw firsthand how powerful it is to have a clear, personalized plan and the right mindset to support it. With the incredible technology we have now, I was compelled to create this app in order to take the guesswork out of achieving your dream physique and give you the most superior tools I wish I had when I started! My background is in computer engineering so finally was able to merge the computer engineering with the fitness!

This app combines everything I’ve learned from years of coaching—how to train effectively, eat for your goals, recover properly, and track real progress. I’ve built in features to estimate body fat, analyze your photos and measurements, and provide macro guidance, so you always know exactly what to do next.

My goal is that this app becomes your trusted guide, helping you build not just a better body, but a stronger, more confident mindset that will positively affect every area of your life! I’m excited to share with you the same proven system I've used along with millions of others and see how far you can go!

Hi Hugo, I’m writing you to thank you for helping me achieve one of the greatest, if notgreatest achievement in my life. That’s my after picture. I went from a soft physique at 160-lbs to the leanest I’ve ever been in my life while weighing 170-lbs. I followed your Body Re-Engineering System principles diligently over a period of about 18 months and achievedsomething I never thought possible..gaining muscle while losing body fat.Thank you for your fantastic contribution to my life and the lives of so many others I’m sure.The way I feel when I look in the mirror now is incomparable and it’s thanks to you. I wouldbe happy to refer you to anyone looking to make changes in their lives and in fact, I do.

Ron Graves testimonial photo
I’ve struggled with my weight for the past 25 years. I went from being a skinny kid, to anobese adult. I wasn’t just packing 40 or 50 extra pounds — I was anywhere between 70 and110 pounds overweight, which is clinically obese and clearly a health risk. I was fat and miserable. My family life and relationship were suffering. I had enough of being fat so I joined a gym.

Then last year I read few articles that Hugo Rivera wrote and I took a longshot and reached out to him for help. To my surprise he wrote me back, set me in the rightdirection, and got started with his Body Re-Engineering program.

His first order of business was to teach me that weight loss is a physical and mental game. I needed to believe that it was possible, because otherwise, well, it just was not going toaccomplish anything.

He never accepted less than 100 percent, and he pushed me to do things I would never have done on my own.

Hugo saw the potential in me and wanted me to see it as well.We focused on setting goals and using a journal to keep myself accountable. Size, more than a target weight, was the most important thing to me.

When I went down a size, I would buy myself an item of clothing I had my eye on — clothes were my goals!

I had to really work to get an article of clothing, but it was worth it. Within a few weeks, I’d replaced my usual food rewards with something even better — a new and improved me.

I had lost 45 pounds since last year. I took everything I learned from Hugo and kept the weight off.

He taught me to love myself and put myself first. It’s not always easy, but I’ve realized that I’m worth all of the hard work.

This program helped me realize there was no quick fix for healthy weight loss and providedvaluable information that helped turn my life around.

Hugo gave me the confidence to step into the gym and commence weight training, something I had never done before.

The visualization tool provided got me through moments when I felt myself almost giving up.

I was empowered by the knowledge and information. I had no idea about supplements and how to structure a weight training program.

I felt so guided with the programs that was provided!

Just over a year ago, I weighed 215 pounds and hit my lowest point. I was extremely unfitand was totally fed up with my weight and how I was feeling.

With Hugo’s help, I lost 37k (81.4 lbs) and went from obese to Australian National bodyshaping competitor in 12.5 months!

I just don’t love my weight loss, I love my new found confidence and love of life!

I am more in touch with people and the world again. I’m now always challenging myself in every aspect of my life.I have recently enrolled in a course to become a qualified personal trainer.

I am passionate about helping others realize their own potential and having a positive impact on their health whilst doing something I love.

I cannot thank you enough for the positivecontributions you made not only in my transformation, but to my life!

Hi Hugo, I just wanted to give you a little feedback on how your natural bodybuilding exercise & nutrition program has helped me.

I started following your program in late Febuary and have lost approximately 30 pounds andadded some significant size. My body fat percentage is now around 12.5%.I have a couple of recent photos that I took as part of a 30-day rapid-results fitnesscompetition. I just submitted my photos and other information so I’m not sure how I did yetbut following your program certainly helped me get the results I wanted.I’m now trying to get under 10% body fat and get some additional size. I’m even thinkingabout trying a competition for the over 40 crowd. Just so you know, I’m 6′-3′′, 215 lbs.Thanks for all you do!

The principles of this system pretty much saved my life. Hugo’s guidance and the principles from Body Re-Engineering allowed me to beat anorexia and gain over 20 lbs of muscle naturally in 6 months. The progress was so incredible that I decided just for fun to try a natural bodybuilding competition. I used the fat loss principles of the system and ended up losing all of the fat while gaining around 5 more lbs of muscle in the process. Much to my surprise, I actually ended up winning the whole competition!

After the competition I just decided to stay inshape but not in an extreme manner. Again, using the Body Re-Engineering principles I was able to easily modify my body to the way that I wanted to! It is just easy when you have the right plan that works with your body and not against it

Chad Rivera testimonial photo
So I started out at 230-lbs and with this program I was able to get down to 180-lbs after a year (first pic to the left).

Then after a second year of applying the workouts and the diets (changing the diet so that I could eat more as my metabolism increased) I kept losing fat as I was gaining muscle.

The end result is that now, I weigh 177-lbs (pic to the right) but much bigger and leaner than in my previous two pictures.

The bottom line is that the program works. If you have the will to apply the principles and change your body, then you cannot go wrong with this.

Simply follow the routines and the diet principles and the body will do the rest.

And if you really follow it to the letter, not only will you look better but your health will improve dramatically as well. Give it a shot and see for yourself! Don't take my word for it!

Nikki Gregoris testimonial photo
This man helped me go from 25+% body fat to under 17% body fat. Most importantly, he fixed my reactive hypoglycemia. If you aren't familiar with this term, it means a drop in bloodsugar following a meal between 2-4 hours. I literally could not function as a human being.

Hugo looked at my situation and current program, modified it and repaired my metabolism within 6 months!

Due to my high percentage of body fat and my blood sugar condition I was literally only able to tolerate 100 grams of carbs a day; at the most.

In fact, the situation was so bad that my doctor actually ran tests to make sure I wasn't becoming a diabetic at my early age!

Thanks to Hugo’s safe and sensible programs I now eat over 2,000 calories a day and I am now consuming between 250-300 grams of carbs a day without any problems!

Furthermore, I no longer have issues with my hormones anymore.

I cannot recommend Hugo’s programs enough!

As far as motivation goes, initially I wanted to get in shape in order to defeat the diabetes and get off of the meds.

My doctor explained that it was possible but that most people usually have to take the meds for the rest of their lives so to "try not to worry about it too much and see if you can lose a little weight if you can", according to my Doc.

It was that possibility of dropping the meds and losing weight that gave me the desire to start a program. I really had a wake up call, so to speak.

Now my desire is to get cut and bigger by next summer when my oldest daughter is getting married. It might take another year, or even two, but I am determined.

I see some of these ads on TV about getting so amazingly in shape and cut in 90 days. I don’t think that is possible for most people and the slow and steady approach has been just fine for me. Now I see such small differences on just a weekly basis as I feel a different muscle start to kick in. It is really cool when that happens!

Changing my routines in the way Body Re-Engineering teaches, and seeing different muscles start to grow, and the shape of my body change for good is amazing and I can never wait to see what the next phase brings!

About a six months ago I was actually asked if I was a body builder at a local diner that my wife and I go to. I burst out in laughter. My answer was no, but I did admit to working out.

It was when I had just qualified as a Fitness Instructor/Personal Trainer that I started to use the Body Re-Engineering principles. Although I knew the basics of training, I had no idea of how to approach a competition.

Thus, I started to use the Body Re-Engineering principles. Using the support system to the fullest along with the Body Re-Engineering principles completely changed my body and my life!

My body changed shape and my muscle tone increased.The training and diet were tough, however when I kept seeing the results of the hard work, it helped push me forward to continue to follow the plan. I knew I was in good hands!

I competed and placed 3rd. I cannot describe how much confidence I gained from being on stage!

I first came across Hugo 2 years ago.

I was chubby as a kid and a young teenager until I was about 15; that’s when i started to care about my looks and appearance and its the age girls start to notice you so I was very determined to get rid of the fat (which I did), but as a resul, I went really skinny and was eating very little and the food I was eating was not healthy food.

Even though I was happy, at the time I realized that I had gone too skinny (weighing only 9 stone) and needed to put some muscle on, which is what the girls seemed to like on a boy, which was another reason (along with being healthy) that motivated me.

I trained with weights for around 2 years but even though I put on muscle and strength (every one does when they first start) my diet and training were very poor and I stopped putting on any muscle or strength for over a year.

I knew I had the determination but i just needed the right guidance and knowledge.

So at age 18, I came across Hugo’s system and little did I know this was about to change not just my bodybuilding ressults, but my entire life forever!

After going through the whole system I started to use it and I had amazing results!

After my first clean bulk cycle I got to 15 and half stone and put on a lot of muscle and strength! By the way, this is all natural, which is amazing!

I am now aged 20 and weigh a lean 14 stone with around 8 percent body fat!

The knowledge and advice Hugo has given me over the years through his Body Re-Engineering membership will not be forgotten. I am so grateful!

The massive point which made me take a shine to Hugo was that hes a natural bodybuilder because if he wasn’t I might not have been so keen to look into his materials.

The fact that he’s a natural bodybuilder, also used to be chubby, got super skinny (anorexic in his case) and now is in amazing shape makes him the perfect person to connect to young people starting off so they can be set in the right direction.

I know a few people who live where I do who have gone to the wrong gyms and have been influenced by the wrong men who were convinced to take steroids at early ages such as 15!

Lucky for me I was never interested one bit in stuff like that. I knew I could do it naturally with hard work and Hugo represents everything that is good about bodybuilding.

He always made time to reply to my problems and give me advice on bodybuilding. Hugo is also an amazing human being; he is a top guy in the industry and yet he’s very humble.

He wants to give all his knowledge to us and influence us in the right manner preventing us from making all of the mistakes he made at the beginning.

I can say that using Hugo’s principles has not only changed me physically for the better but mentally as well!

Themental boost and confidence you get from looking and feeling good with compliments of people is really good. I’d strongly recommend his Book Re-Engineering system and membership, Thanks Hugo and keep up the good work!

Beth Bertone testimonial photo
Across those 18 months, I went from 147-lbs to my stage weight of 118-lbs. Who would’ve thought that such a transition could be possible for a 49-year-old manager, fitness instructor, mother, and wife.However, it wasn’t a walk in the park.

I battled through many obstacles: a full business schedule with a lot of travel, the death of my father, an injury to my right shoulder, and a cancelled competition.

But it was Hugo who reassured me that I could and would overcome these obstacles which would typically hold a person back.

Yes, I am determined, strong-willed, and stubborn when I set my mind to a goal – and I’m sure my family would agree -- but I would not have been successful without the support of Hugo.

They helped me get back on track and adjust my training and meals. It is because of this help that, on October 26th of the year I competed, I was wearing high heels on a stage in front of many, performing a step-by-step routine, much like the woman I’d observed at the YMCA many years prior, earning me 4th place in my competition.

If you are reaching for the stars and going outside of your comfort zone, and you are determined, disciplined, but know you need help, be sure to use Hugo's Body Re-Engineering system. I have not only benefited from his knowledge and experience, but I’ve also walked away a richer person!

For many years I tried many systems on and off, but only got marginal results, which left me frustrated, and as a result, I would stop doing them.

Last year, when I decided to really get back in shape, I contacted my friend Hugo and he referred me to his Body -Re-Engineering system.

As soon as I started to do the Body Re-Engineering workouts and diet, I noticed that I was not only building massive muscles, but started to lose body fat at a super accelerated rate!

This kept me motivated and as a result I stuck to the system.

This system just blows everything else away! I gained over 25 lbs of Rock Solid Muscle and lost over 35 lbs of fat. In addition, these are permanent results and I just keep getting better and better. Nothing can compare to this and I can tell you that I’ve tried just about everything else out there! Give it a try. You won't be disappointed.

I had the pleasure of starting the Body Re-Engineering System a year ago when I decided to finally add a significant amount of muscle to my frame with emphasis on my glutes, hips and legs while at the same time building muscle in my upper body in order to look balanced.

I also had the goal of adding a significant amount of strength while at the same time making sure that I would retain my femininity.

While this was a tall order, Hugo assured me that it could be done, and if that I believed I could achieve it, that was half the battle. The other half was following the system.

It was hard at first because he asked me to eat much more than I was used to. But I went ahead and did it as he advised, and started following the detailed workouts, taking my supplements (which are mostly a variety of vitamins, minerals and natural performance enhancing ones like creatine and arginine (which have proven to be amazing supplements for women's health as well), sleeping 8-9 hours every noght (as that is what my body needs but everyone is different) and finally consuming all my macros.

Fast forward a year later and now I can do close grip pull-ups on my own for 8-12 reps, 135lbs on the flat bench press for 15-20 reps, 900 lbs on the leg press for 50 plus reps, etc. On top of that I gained a tremendous amount of endurance (I do my workouts now and don't even break a sweat even though I am working hard) and gained a total of 21 lbs in a year while losing a couple pounds of fat! All of this while still retaining my femininity!

I couldn't be any happier! I don't use anything hormonal nor even peptides. Again, my supplements are all natural!

This system works better than anything I have ever encountered. I have been training since 12 year of age and could not get past 129 lbs and now I am at 150 lbs due to all the extra muscle I've gained. While my waist actually went down, my glutes and legs grew so much that I had to change my wardrobe.

If you ladies are looking to make some amazing lady gains, this is the system for you!

"After years of trial and error, I built the system I wish I had from day one"

My journey into fitness started like many others—full of confusion, frustration, and endless conflicting advice. I wanted to first simply go from Obese to Skinny but had no clue how to do it and ended up getting anorexic. Thanks to my concerned family that took me to a nutritionist that told me: "Food is not going to make you fat. Only the abuse of the wrong foods will!" With that said I committed to studying nutrition with the aid of my grandfather who was a Medical Doctor. After I stabilized my weight at a measly 95-lbs, a lady friend told me that I would look good if I gained a little bit of muscle. I asked my parents to get me a muscle building magazine so that I could start to learn bodybuilding. After seeing Arnold Schwarzenneger I was hooked!


While at first training under Arnold's routines worked for me (even though I was always excessively sore), I fell into a plateau that I could not overcome. I spent years trying every workout, diet, and supplement, only to find myself spinning my wheels and doubting if real results were even possible. It wasn’t until I committed to understanding the science behind training, nutrition, and recovery that everything changed for me. So I started using the scientific method to see what workout and diet combinatons worked and which ones didn't. By recognizing patterns I started to cycle my training in a way that would push my body for a few weeks with higher volume workouts, followed by a period of training with less volume but heavier weights. This was a huge breakthrough and in combination with all the new knowledge I had now accumulated on nutrition and supplements, gains started to come steadily!

As I began writing fitness books and coaching others, I realized most people struggle not because they lack motivation, but because they’re overwhelmed by information and don’t know where to start! I saw firsthand how powerful it is to have a clear, personalized plan and the right mindset to support it. With the incredible technology we have now, I was compelled to create this app in order to take the guesswork out of achieving your dream physique and give you the most superior tools I wish I had when I started! My background is in computer engineering so finally was able to merge the computer engineering with the fitness!

This app combines everything I’ve learned from years of coaching—how to train effectively, eat for your goals, recover properly, and track real progress. I’ve built in features to estimate body fat, analyze your photos and measurements, and provide macro guidance, so you always know exactly what to do next.

My goal is that this app becomes your trusted guide, helping you build not just a better body, but a stronger, more confident mindset that will positively affect every area of your life! I’m excited to share with you the same proven system I've used along with millions of others and see how far you can go!

Hi Hugo, I’m writing you to thank you for helping me achieve one of the greatest, if notgreatest achievement in my life. That’s my after picture. I went from a soft physique at 160-lbs to the leanest I’ve ever been in my life while weighing 170-lbs. I followed your Body Re-Engineering System principles diligently over a period of about 18 months and achievedsomething I never thought possible..gaining muscle while losing body fat.Thank you for your fantastic contribution to my life and the lives of so many others I’m sure.The way I feel when I look in the mirror now is incomparable and it’s thanks to you. I wouldbe happy to refer you to anyone looking to make changes in their lives and in fact, I do.

I’ve struggled with my weight for the past 25 years. I went from being a skinny kid, to anobese adult. I wasn’t just packing 40 or 50 extra pounds — I was anywhere between 70 and110 pounds overweight, which is clinically obese and clearly a health risk. I was fat and miserable. My family life and relationship were suffering. I had enough of being fat so I joined a gym.

Then last year I read few articles that Hugo Rivera wrote and I took a longshot and reached out to him for help. To my surprise he wrote me back, set me in the rightdirection, and got started with his Body Re-Engineering program.

His first order of business was to teach me that weight loss is a physical and mental game. I needed to believe that it was possible, because otherwise, well, it just was not going toaccomplish anything.

He never accepted less than 100 percent, and he pushed me to do things I would never have done on my own.

Hugo saw the potential in me and wanted me to see it as well.We focused on setting goals and using a journal to keep myself accountable. Size, more than a target weight, was the most important thing to me.

When I went down a size, I would buy myself an item of clothing I had my eye on — clothes were my goals!

I had to really work to get an article of clothing, but it was worth it. Within a few weeks, I’d replaced my usual food rewards with something even better — a new and improved me.

I had lost 45 pounds since last year. I took everything I learned from Hugo and kept the weight off.

He taught me to love myself and put myself first. It’s not always easy, but I’ve realized that I’m worth all of the hard work.

This program helped me realize there was no quick fix for healthy weight loss and providedvaluable information that helped turn my life around.

Hugo gave me the confidence to step into the gym and commence weight training, something I had never done before.

The visualization tool provided got me through moments when I felt myself almost giving up.

I was empowered by the knowledge and information. I had no idea about supplements and how to structure a weight training program.

I felt so guided with the programs that was provided!

Just over a year ago, I weighed 215 pounds and hit my lowest point. I was extremely unfitand was totally fed up with my weight and how I was feeling.

With Hugo’s help, I lost 37k (81.4 lbs) and went from obese to Australian National bodyshaping competitor in 12.5 months!

I just don’t love my weight loss, I love my new found confidence and love of life!

I am more in touch with people and the world again. I’m now always challenging myself in every aspect of my life.I have recently enrolled in a course to become a qualified personal trainer.

I am passionate about helping others realize their own potential and having a positive impact on their health whilst doing something I love.

I cannot thank you enough for the positivecontributions you made not only in my transformation, but to my life!

Hi Hugo, I just wanted to give you a little feedback on how your natural bodybuilding exercise & nutrition program has helped me.

I started following your program in late Febuary and have lost approximately 30 pounds andadded some significant size. My body fat percentage is now around 12.5%.I have a couple of recent photos that I took as part of a 30-day rapid-results fitnesscompetition. I just submitted my photos and other information so I’m not sure how I did yetbut following your program certainly helped me get the results I wanted.I’m now trying to get under 10% body fat and get some additional size. I’m even thinkingabout trying a competition for the over 40 crowd. Just so you know, I’m 6′-3′′, 215 lbs.Thanks for all you do!

The principles of this system pretty much saved my life. Hugo’s guidance and the principles from Body Re-Engineering allowed me to beat anorexia and gain over 20 lbs of muscle naturally in 6 months. The progress was so incredible that I decided just for fun to try a natural bodybuilding competition. I used the fat loss principles of the system and ended up losing all of the fat while gaining around 5 more lbs of muscle in the process. Much to my surprise, I actually ended up winning the whole competition!

After the competition I just decided to stay inshape but not in an extreme manner. Again, using the Body Re-Engineering principles I was able to easily modify my body to the way that I wanted to! It is just easy when you have the right plan that works with your body and not against it

So I started out at 230-lbs and with this program I was able to get down to 180-lbs after a year (first pic to the left).

Then after a second year of applying the workouts and the diets (changing the diet so that I could eat more as my metabolism increased) I kept losing fat as I was gaining muscle.

The end result is that now, I weigh 177-lbs (pic to the right) but much bigger and leaner than in my previous two pictures.

The bottom line is that the program works. If you have the will to apply the principles and change your body, then you cannot go wrong with this.

Simply follow the routines and the diet principles and the body will do the rest.

And if you really follow it to the letter, not only will you look better but your health will improve dramatically as well. Give it a shot and see for yourself! Don't take my word for it!

This man helped me go from 25+% body fat to under 17% body fat. Most importantly, he fixed my reactive hypoglycemia. If you aren't familiar with this term, it means a drop in bloodsugar following a meal between 2-4 hours. I literally could not function as a human being.

Hugo looked at my situation and current program, modified it and repaired my metabolism within 6 months!

Due to my high percentage of body fat and my blood sugar condition I was literally only able to tolerate 100 grams of carbs a day; at the most.

In fact, the situation was so bad that my doctor actually ran tests to make sure I wasn't becoming a diabetic at my early age!

Thanks to Hugo’s safe and sensible programs I now eat over 2,000 calories a day and I am now consuming between 250-300 grams of carbs a day without any problems!

Furthermore, I no longer have issues with my hormones anymore.

I cannot recommend Hugo’s programs enough!

As far as motivation goes, initially I wanted to get in shape in order to defeat the diabetes and get off of the meds.

My doctor explained that it was possible but that most people usually have to take the meds for the rest of their lives so to "try not to worry about it too much and see if you can lose a little weight if you can", according to my Doc.

It was that possibility of dropping the meds and losing weight that gave me the desire to start a program. I really had a wake up call, so to speak.

Now my desire is to get cut and bigger by next summer when my oldest daughter is getting married. It might take another year, or even two, but I am determined.

I see some of these ads on TV about getting so amazingly in shape and cut in 90 days. I don’t think that is possible for most people and the slow and steady approach has been just fine for me. Now I see such small differences on just a weekly basis as I feel a different muscle start to kick in. It is really cool when that happens!

Changing my routines in the way Body Re-Engineering teaches, and seeing different muscles start to grow, and the shape of my body change for good is amazing and I can never wait to see what the next phase brings!

About a six months ago I was actually asked if I was a body builder at a local diner that my wife and I go to. I burst out in laughter. My answer was no, but I did admit to working out.

It was when I had just qualified as a Fitness Instructor/Personal Trainer that I started to use the Body Re-Engineering principles. Although I knew the basics of training, I had no idea of how to approach a competition.

Thus, I started to use the Body Re-Engineering principles. Using the support system to the fullest along with the Body Re-Engineering principles completely changed my body and my life!

My body changed shape and my muscle tone increased.The training and diet were tough, however when I kept seeing the results of the hard work, it helped push me forward to continue to follow the plan. I knew I was in good hands!

I competed and placed 3rd. I cannot describe how much confidence I gained from being on stage!

I first came across Hugo 2 years ago.

I was chubby as a kid and a young teenager until I was about 15; that’s when i started to care about my looks and appearance and its the age girls start to notice you so I was very determined to get rid of the fat (which I did), but as a resul, I went really skinny and was eating very little and the food I was eating was not healthy food.

Even though I was happy, at the time I realized that I had gone too skinny (weighing only 9 stone) and needed to put some muscle on, which is what the girls seemed to like on a boy, which was another reason (along with being healthy) that motivated me.

I trained with weights for around 2 years but even though I put on muscle and strength (every one does when they first start) my diet and training were very poor and I stopped putting on any muscle or strength for over a year.

I knew I had the determination but i just needed the right guidance and knowledge.

So at age 18, I came across Hugo’s system and little did I know this was about to change not just my bodybuilding ressults, but my entire life forever!

After going through the whole system I started to use it and I had amazing results!

After my first clean bulk cycle I got to 15 and half stone and put on a lot of muscle and strength! By the way, this is all natural, which is amazing!

I am now aged 20 and weigh a lean 14 stone with around 8 percent body fat!

The knowledge and advice Hugo has given me over the years through his Body Re-Engineering membership will not be forgotten. I am so grateful!

The massive point which made me take a shine to Hugo was that hes a natural bodybuilder because if he wasn’t I might not have been so keen to look into his materials.

The fact that he’s a natural bodybuilder, also used to be chubby, got super skinny (anorexic in his case) and now is in amazing shape makes him the perfect person to connect to young people starting off so they can be set in the right direction.

I know a few people who live where I do who have gone to the wrong gyms and have been influenced by the wrong men who were convinced to take steroids at early ages such as 15!

Lucky for me I was never interested one bit in stuff like that. I knew I could do it naturally with hard work and Hugo represents everything that is good about bodybuilding.

He always made time to reply to my problems and give me advice on bodybuilding. Hugo is also an amazing human being; he is a top guy in the industry and yet he’s very humble.

He wants to give all his knowledge to us and influence us in the right manner preventing us from making all of the mistakes he made at the beginning.

I can say that using Hugo’s principles has not only changed me physically for the better but mentally as well!

Themental boost and confidence you get from looking and feeling good with compliments of people is really good. I’d strongly recommend his Book Re-Engineering system and membership, Thanks Hugo and keep up the good work!

Across those 18 months, I went from 147-lbs to my stage weight of 118-lbs. Who would’ve thought that such a transition could be possible for a 49-year-old manager, fitness instructor, mother, and wife.However, it wasn’t a walk in the park.

I battled through many obstacles: a full business schedule with a lot of travel, the death of my father, an injury to my right shoulder, and a cancelled competition.

But it was Hugo who reassured me that I could and would overcome these obstacles which would typically hold a person back.

Yes, I am determined, strong-willed, and stubborn when I set my mind to a goal – and I’m sure my family would agree -- but I would not have been successful without the support of Hugo.

They helped me get back on track and adjust my training and meals. It is because of this help that, on October 26th of the year I competed, I was wearing high heels on a stage in front of many, performing a step-by-step routine, much like the woman I’d observed at the YMCA many years prior, earning me 4th place in my competition.

If you are reaching for the stars and going outside of your comfort zone, and you are determined, disciplined, but know you need help, be sure to use Hugo's Body Re-Engineering system. I have not only benefited from his knowledge and experience, but I’ve also walked away a richer person!

For many years I tried many systems on and off, but only got marginal results, which left me frustrated, and as a result, I would stop doing them.

Last year, when I decided to really get back in shape, I contacted my friend Hugo and he referred me to his Body -Re-Engineering system.

As soon as I started to do the Body Re-Engineering workouts and diet, I noticed that I was not only building massive muscles, but started to lose body fat at a super accelerated rate!

This kept me motivated and as a result I stuck to the system.

This system just blows everything else away! I gained over 25 lbs of Rock Solid Muscle and lost over 35 lbs of fat. In addition, these are permanent results and I just keep getting better and better. Nothing can compare to this and I can tell you that I’ve tried just about everything else out there! Give it a try. You won't be disappointed.

I had the pleasure of starting the Body Re-Engineering System a year ago when I decided to finally add a significant amount of muscle to my frame with emphasis on my glutes, hips and legs while at the same time building muscle in my upper body in order to look balanced.

I also had the goal of adding a significant amount of strength while at the same time making sure that I would retain my femininity.

While this was a tall order, Hugo assured me that it could be done, and if that I believed I could achieve it, that was half the battle. The other half was following the system.

It was hard at first because he asked me to eat much more than I was used to. But I went ahead and did it as he advised, and started following the detailed workouts, taking my supplements (which are mostly a variety of vitamins, minerals and natural performance enhancing ones like creatine and arginine (which have proven to be amazing supplements for women's health as well), sleeping 8-9 hours every noght (as that is what my body needs but everyone is different) and finally consuming all my macros.

Fast forward a year later and now I can do close grip pull-ups on my own for 8-12 reps, 135lbs on the flat bench press for 15-20 reps, 900 lbs on the leg press for 50 plus reps, etc. On top of that I gained a tremendous amount of endurance (I do my workouts now and don't even break a sweat even though I am working hard) and gained a total of 21 lbs in a year while losing a couple pounds of fat! All of this while still retaining my femininity!

I couldn't be any happier! I don't use anything hormonal nor even peptides. Again, my supplements are all natural!

This system works better than anything I have ever encountered. I have been training since 12 year of age and could not get past 129 lbs and now I am at 150 lbs due to all the extra muscle I've gained. While my waist actually went down, my glutes and legs grew so much that I had to change my wardrobe.

If you ladies are looking to make some amazing lady gains, this is the system for you!
