User reviews

One month after downloading

So far I am very happy with how the app has helped me format my workouts, the video demonstrations and descriptions are very helpful and have shown me how to do exercises I’ve never done. I feel the results of my new exercises and this seems to be just as good as paid apps.

Free review

I enjoy the app it’s great for first time gym users and is super friendly. Lots of options for free users. I can even see the value for the subscription. Not ready to commit to that just yet though personally.

Very user-unfriendly

Very bad selection of exercises. Lots of standard machines not even on there.

Great gym coach

I have followed these exercises with an online coach during four months and getting great results. I found it so good that my wife also joined. I will recommend highly. The best coach on the gym, only if you are serious to develop your muscles and improve your strength. The coach even check how was my diet and recommended some food supplements that have helped.
