Bugs, things not working5%

9 of the 1 and 2 star reviews.

Great App

I’ve been going to a boot camp for 4 months and getting great results, I’m 64 and ready to make my health a priority. However, I strained my back and was out for 4 weeks. This app has helped me get back into my routine again and allows you to set up custom workouts and omit areas that may be in pain. I feel inspired again:)

⚠️ Be Careful Before Using This App!

I purchased a 4-week workout program $19, but I was disappointed with the workouts and stopped using the app before finishing the program. Then I was charged an additional $49 for a subscription I did not knowingly agree to. I am requesting a refund the same day they charged me, and I am very frustrated with this experience. The workouts were not worth the money to me, and the unexpected charge made the experience even worse. Be sure to check the subscription terms carefully before making a purchase so you don’t end up with unexpected charges. I would not recommend this app based on my experience. Stay away if you don’t want to risk unexpected charges!

★★★★★Oct 21, 2026
Newbie

I’m new to working out in this way and I think this was very helpful. It takes you step by step at your own pace. But giving up isn’t an option. So it meets you have way. 😄

WoW

I’m a 68 male, worked out my entire life up until last few years. Decided I wanted to get back into shape, was skinny fat. Started July 2026, as of mid October I have lost 4” in waist while only losing about 7 pounds. I did add weights into my routine in the last 6 weeks, but it was the app’s exercises (I continue to do the body weight exercises daily) that got me to the point I felt I could safely lift again. I feel better than I have in years, my core has never been so strong, my abs are apparent even while wearing a T-shirt. My obliques have never looked like they do now…. Even as teenager. I have shared your app with everyone who asks what I’ve been doing… guy’s half my age struggle to get through the routines I’m currently doing… thanks
