Just begun doing this from the DVD - have done Pilates for a while and am fairly good at that but this makes me ache! Feels like it's getting really deep into the muscles and I may be kidding myself but I think I can feel a difference after about 3 sessions. My only problem is that I may get bored with it before long, but am watching box sets while doing it to keep entertained...
So anyone done this and found it effective?
