I was in need of a change in my workout routine - happened to hear about Runtastic 6 Pack Abs and started with that and added the Leg Trainer to balance things out for myself. I love that it keep track of the days and will remind you but more importantly I can see changes, not just feel them! Great workouts that progress and change before you get adjusted and they get easy so it keeps you on your toes.
