shellers, i have not done the treadmill portions, but i think it was gayle who said that she thinks some of the exerecises they have you do broke her TM. i think there is something where you don't actually have your TM on, but you move the belt with your feet.
the non-TM portions are pretty tough. especially since everything is done on FOUR RISERS!!!!!!!!!!!!!!!
can't wait to hear what you think. i did legs on saturday and am still feeling it!
