S&S may be better for you in the long run, less exhaustive work, quicker recovery, and best of all, the stretches, warm up exercises and the two main exercises are a whole body workout. I have lost 15 pounds, gained flexibility, and felt overall better than I have in a few years. At 50, with mobility declining, this is a revelation for me. I am more flexible, agile, getting stronger, and less aches in my hips, knees, or back.
