I wanted to add to this post to encourage others to give it a try. The workouts I am doing are two or three times a week. Nate at Endurance rehab said that just twice a week, you will make great gain in strengthing weak areas. And the benefit of strengthening core muscles, and shaping the legs unlike any weight machine has ever done!

My workouts consist of only 6-8 of the exercises, and I am done in just 30 minutes. Not hours here, just thirty minutes!
