So a few not so user friendly things...

1. It doesnt give you an audio indicator to move on to your next move . (Because it blacks out, you lose time in trying to navigate through to the next excercise)
2. It doesnt give you the option of doing a workout that is not at the gym. Those that dont seem to be totally at the gym assume you have all the gym equipment you need.
3. It does not give you the option to change out one excercise for another.
4. It does not give you the option of inputting personal data to measure calorie count, etc.

Basically, if I want a plan to follow I can pick out what this program gives me out of a magazine.
