This fitness app has a workout regimen with proven results.
The app is a simple workout plan that changes up over the course of 4 days. Moreover, the rest intervals are timed and the app has a timer that keeps you on track. The reason why the intervals vary is to challenge you body’s ATP production, burn calories and help you develop real functional strength that can apply to sports (not just gym, 1 rep max strength).
