It's very helpful
This app really helped me with cross country. Of course I don't need it for my birthday but of course for my legs and hips. I'm a 7th grader and I love fitness Soo much! So Keep making apps like these please
This app is good! I can feel the changes :) it would be nice if it has alarm or reminder since I'm a lazy-ass
