Good but some bugs
I really like the workouts an exercises of each programm but in some programms there are little mistakes. For example the programm body shock. Sometimes the video starts to early or there are the double quantity of exercises on a special workout day. That could be fixed than i would rate with five stars ! But i really have to appriciate to the whole undersun team for giving us auch a great app m the possibility to train at home or anywhere we want !
