AMAZING for men and women alike

This is the perfect strength training app for anyone from well-versed weightlifters to newbies worried about venturing into the weights section at the gym. As a young woman, getting into strength training can be intimidating, which is why I love that FitnessAI shows you exactly how much of each exercise to do, and how to do them properly. This way you don’t have to worry about your routine and can focus on your actual workout.

It may sound crazy, but this AI is probably exactly what my routine needed, as someone who has been working out consistently but hit a plateau. The routine pushes you just enough so you’re always being challenged and getting stronger, but not beyond what it knows you’re capable of.

It’s been about a month and I feel great already. I’m the strongest I’ve ever been and the fun and easy-to-use interface leaves me itching to go back to the gym as soon as I finish my workout. I’ve already told all my friends about the app and will continue to do so. Thanks, FitnessAI!

Overall a solid app but needs a few additions

I’ve been using this app for almost a month now and for the most part I’m happy with it. I like not having to plan specific exercises and the rep count. The app takes care of that and gradually increases the difficulty of those workouts.

I do think that the app needs a few things to keep up with the competition. First and most importantly you need to be able to substitute exercises during a workout. On leg day I wasn’t able to do 3 of the exercises it prescribed because my gym didn’t have those leg machines. The app should have a database of exercises (organized by muscle group) that can be subbed in. Second it would be great to have an optional rest timer that would be triggered when you complete a set.

With these changes I would be willing to give the app 5 stars as its algorithm is better than any of the other workout apps I’ve tried.

Hey Marc — done and done! Subbing out exercises will be live any day now and a rest timer is on its way!

Thanks for the feedback :)

I NEVER review apps and I never pay for them.

I am almost 45 and have never regularly gone to the gym. I’ve hated it because I never really new what to do and could never remember what I did the time before. Beside that I felt embarrassed to ask other muscle bound dudes for help. This is the first time I’ve stuck with it and I am seeing real gains. This app is great because it changes stuff up and keeps track of everything for you. I also love the added animation that shows you how to preform the workout. Besides all this really great stuff. You can also text Jake and he’ll give you advice concerning technique and other stuff like that.

This app is worth it for sure, no matter what your exercise experience is. And this is coming from a guy that never pays for apps!
