Just did this one and loved it. I like it better than the original mostly because I love doing upper body on the ball and the first one seems a little to long for me. After having 2 shoulder surgeries, I don't like my upper body workout to be too long. I thought Cathe was crazy going to light but I thought for my 1st time with it, I would match her weights. I did for back & chest but decided to up it for tri's because it seemed to easy. By shoulders and bi's I was back to Cathe's weight. My arms are still quivering!!! Thanks for another winner. Can't wait to try PP Lower body later this week.
