Almost Perfect
Ive been using the app for more than a year for my primary exercise routine. Its a great partner, provides sufficient alternative routines and allows you to make custom routines. Examples of different exercises are well-done and enable you to clearly see the moves. My only criticism is that the customization is limited to only certain default choices for duration of exercise and rest periods (though probably for good reasons).
