how often can you do the xtension program?
it doesn't seem to be too taxing muscularly, so can you practice every day or say like 5 or 6 times a week?
it's a great program anyway and my shoulders, chest and back are feeling fantastic as a result. i have only been practicing 3 times a week but feel i could probably do it more often....
also did a 100 rockits non-stop today with the 5lb clubs!
