I absolutely love this program! The exercises are varied yet specific; one can feel them at work. The pace is good; building up as you advance. It is clean & easy to follow. I like being able to create your own routine once you have completed the levels. I like everything about this program, wouldn't change a thing! Congratulations on doing such a good job creating this. ....And Thank You!

Kind of monotonous, and I would rather see a real person rather than a computer generated one, but I'm sore!

I've been doing weights and weight machines and thought this app seemed too easy. I was pleasantly surprised. It is much better than I expected.
