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!

Just okay

I appreciate the concept and UI but this app is for beginners. For one, the exercise library is very limited, a lot of simple exercises aren’t a part of the program ( how does it not have incline barbell press??). I personally don’t think that incrementally increasing the weight on a limited number of weekly exercises is enough in the long term, your muscles need variety! The most frustrating thing about this app besides its limited exercises is the rep range limits it places on workouts. Say for instance the AI says you should do 8 reps at a certain weight but you’re able to push out 10—you’re not able to log anything past 8, so the AI doesn’t register that and won’t adjust the weight properly, instead you have to find a heavier weight until you fail at 8, that’s kind of stupid don’t you think? I also wish it sent you weekly recaps of your progress like the Bodybuilding app because that’s very motivating and the app already has all this data so why not do something useful with it? Hope the developers read this because I like this app and want it to improve!

Hey Yassmann, thanks for your feedback.

- we recommend incline dumbbell press, perhaps you were too quick to judge!
- if you can do more reps, increase the weight (this is intentional)
- you need to forget what you think you know and listen to the data 🤓

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 :)
