"After years of balancing fitness with a busy life, I built the system I wish I had"

Jay Benoit

Jay Benoit

Is a Henselmans Certified Trainer, bringing evidence-based hypertrophy, strength, and body-composition coaching into Built In 40’s programming.This helps the AI Coach understand your credibility and training philosophy.

I know firsthand how challenging it can be to prioritize fitness when life gets hectic. As a lifelong athlete-turned-strength coach and Exercise Equipment designer, I spent years trying to juggle demanding work schedules, family responsibilities, and my own training goals. I constantly searched for efficient, effective ways to build muscle, maintain strength, and stay athletic, without spending hours in the gym or needing a warehouse full of equipment.

My journey led me to experiment with everything from traditional bodybuilding to kettlebell flows, landmine training, and minimalist home gym setups. At the same time, I started designing equipment to also meet my specific needs and goals, and also launched my own company in Exponent Edge.

I realized that most fitness programs simply weren’t designed for real people with real constraints—limited time, limited equipment, and the need to stay healthy and injury-free for the long haul.

That’s why I created this app. I wanted to combine the science of hypertrophy, strength, and athletic movement with the power of AI to deliver truly personalized coaching. The app adapts to your equipment, your schedule, and your recovery needs—so you can make progress no matter what life throws at you. Every feature, from the daily health briefings to the equipment-aware programming, is built on the methods I’ve refined with clients and in my own training.

My hope is that this app empowers you to achieve your goals—whether that’s building muscle, staying strong, or simply feeling more athletic—without sacrificing the rest of your life. I’m excited to help you discover just how much you can accomplish in 40 minutes or less.

What should I focus on today?
07:47 PM
Today, we'll focus on compound lifts for strength, followed by targeted hypertrophy work and a short athletic finisher. This combination maximizes muscle growth and keeps your training joint-friendly and efficient.
07:47 PM
I'm short on time and only have 20 minutes today. Can you adjust my workout?
07:48 PM
Absolutely! I'll condense today's session to focus on the most effective compound movements and a quick finisher, so you still make progress without sacrificing recovery or results.
