I know you guys will think I'm crazy but I'm doing the August 05 Rotation, and today was the boot camp 2x. This morning I only had time to do it once, so I wanted to see if I could do it back to back so I did it 2x more around 6:30 p.m. It really wasnt hard at all, I felt really good when I was doing it. But I will say right now my knees and legs are feeling a little sore. I'm sure I will feel it even more tomorrow. Lori BC
