MuscleMind's answer

MuscleMind pays you in $MUSCLE rewards every time you train. This is unique for a fitness app and will motivate you even more to keep going to the gym and earn more rewards. Another unique feature, is how your weekly workout plan evolves. Every week, it gets updated based on all your historical training data and the feedback you give your trainer. This results in a highly personalized workout plan that fits every user.

MuscleMind's answer

Built by a lifter, for lifters. I'm Jelle Heijne, a 28-year-old mechanical engineer from Eindhoven, Netherlands. By day I work on hydrogen combustion engines. MuscleMind is what I build at night.

Why I built this I've been going to the gym on and off since I was 16. And that's exactly the problem — on and off. Some months I'd train consistently and feel great. Other months I'd lose motivation, skip sessions, and lose the progress I'd built. When I did show up, I lacked structure. I'd record my lifts in Excel for two weeks, then stop. I plateaued.

I knew what I needed was a personal trainer who could keep me both structured and accountable — but I couldn't afford one. When ChatGPT came out, I saw the opportunity. If AI could understand my training history and adapt to my performance, it could do what a trainer does — without the €80 per session price tag. I spent two years building that idea into MuscleMind.

What makes it different The consistency problem has two sides: structure and motivation. MuscleMind is built to solve both.

On the structure side, the AI Coach remembers every rep you've ever logged, every piece of feedback you've given it, and every week it builds you a completely new plan that progresses automatically from where you left off. Progressive overload — the principle that you have to consistently lift more over time to keep getting stronger — is built into every plan, automatically. You never have to think about whether you're actually making progress. You just follow the plan.

On the motivation side, every workout you complete earns you $MUSCLE — our in-app reward currency you can redeem for discounts. Showing up should feel rewarding. Trainers charge you. We pay you.

Built by someone who uses it I'm not a certified personal trainer. I have no formal fitness credentials. What I do have is personal experience with exactly the problem MuscleMind solves — years of inconsistent training, lost progress, and frustration — plus a degree in mechanical engineering and two years of learning UI/UX design and Flutter development to build the solution.

I've been using MuscleMind myself for two months now. The difference is real. I train at the gym twice a week and I never walk in wondering what to do — I follow the plan, log my sets, and the app takes care of everything else. I'm making measurable progress, consistently, for the first time.
