🇫🇷A real game-changer! Since I started using this app, my workouts have reached a whole new level. The interface is intuitive and the programming is spot-on. It feels like having a personal coach in my pocket handling everything: movements, rest times, tracking... The best part? Being able to swap an exercise for another one targeting the same muscles. I can't train without it anymore.

Frequently asked questions
How long will it take to build muscle?
It depends on your starting point, consistency, nutrition and recovery, and no program can promise a timeline. Your WorkoutGen program increases your training volume over successive cycles, and you can log your weights for free to track your progress.
Do I need a gym membership?
No. At the gym, the muscle gain program uses barbells, dumbbells, machines and cables. At home, choose “Without equipment”: it uses your bodyweight, with push-ups, squats, lunges and variations at a difficulty suited to your level. You can replace an exercise for free with an equivalent alternative.
How many workouts per week for muscle building?
Three to five workouts per week suit most people. You choose your number of workouts and days when creating your program, and it adapts to them.
Is the muscle gain program really free?
Yes. You create your personalized program and follow your workouts for free, with videos, the player, timer and weight tracking, without a credit card. Max adds AI-recommended weights, AI Coach reports, a focus you can change whenever you want, all progress dashboards and complete program customization.
Is this a good muscle gain program to build size?
Yes. It organizes your hypertrophy volume into cycles, with progressive overload adapted to your level, to build muscle rather than simply gain weight.
Can beginners follow this muscle gain program?
Yes. It adapts to your level with the right starting volume and exercises, then progresses with your sets to keep building muscle.
What are the best exercises to build muscle?
Big compound lifts such as the bench press, row, squat and overhead press are the foundation of muscle gain, and your program complements them with the right accessory work for each muscle.
Can I prioritize certain muscles while gaining muscle?
Yes. When creating your program, choose your focus: one or more groups from Legs, Glutes, Back, Chest, Abs, Shoulders and Arms. They get more emphasis in your workouts while your whole body remains trained every week. With Max, you can change your focus whenever you want, for one workout or your entire program.
