I have a problem with my heel right now so I have not been able to do my daily walk of 3 1/2 miles a day. I was doing my bike, but getting kind of sick of it. I saw this program being advertised and I thought I would give it a try. I absolutely love it. Amazing what you can do in a chair. I am progressing so I am able to now do some of the exercises on my feet. You can do weights, cardio, yoga, kickboxing, and balance. I am 71 years old so those are all things that I need to do to stay healthy. Thank you Deron. It is a great program.
