HI

I probably didn't explain it very well. You get on your knees and the wheel (thats what I call it) is controlled by both hands. You extend it out across the floor as far as you can making sure to squeeze your stomach muscles and then you roll the wheel back toward your body. I am sure lots of you have seen the commercials for it. It looks easier than it is. But then all the excercise equipment usualy is right?
