Honestly...I don't hurt! I have way more muscle(s) than I started with and just feel much better since I have been working out daily! This is HUGE for me as I really have never liked to sweat and I can't believe I am sticking with it. I had a crazy thought today that after I am done...I may do level two and three again ;) I really have liked this DVD and it's not half bad. Just thought you should know!!!
