THIS APP IS AWESOME
With multiple exercises divided by muscle group, instructional videos, tracking and workout log in iCal form and training regimens divided by goal and time, you cant go wrong with this app!!! I use it while Im at the gym to log my reps as well as to look up new exercises when I get bored. I havent even used all the features like music etc. and I am totally sold! Also, it has not deleted my custom exercises. 2 words about this app- WORTH IT!
