I would give it 5 stars because of the voice counts out the reps and sets as well as rests. Its easy to follow the program and if I dont know what to do I look at the really easy to understand instructions. But I gave it 4 because one of the exercises (side crunch) is supposed to be 2 sets and I had to rewind the workout to work on my other side.
Its like having a trainer in my pocket, which is good for me because I work on the oil rigs..... Very sedentary until now.
