Has anyone tried this? The promise is a ten years younger body in ten hours (about 2 one hour sessions per week). I can't find a single bad review of this system on the internet, but I'm definitely finding that it's as I get better and understand the exercises more that I'm finally feeling a difference. So I'm not sure my first 3-4 hours really counted. So has anyone had any experience with this exercise system and if so, how did you all like it?
