"I just finished this awesome workout. Man! I am still catching my breath. It worked strength, cardio. Probably the best workout I've had in months. I feel my blood pumping and I feel like I got a lot done today. I feel good about myself. I would recommend this to anybody. This is one of the best methods for rehab and also just strength and cardio. Awesome workout."
