This apps doesn't work well First there is some bugs like we can't trun off walking notification it show up always, and in progress date when we swipe next day the days are one on top of the other. The real problem is when we choice one workout plan like chest & triceps it's 20 min of workout and it's too hard for beginners you have to do fast before the times up don't know for other but for beginners it's hard and dangerous. After i did legs & shoulders workout I have so much pain in my back.
