I have a TreadClimber and it's a great machine. I strongly suggest that you start out slow and view the disc that comes with it. So you will not injury yourself. It takes a few uses to get the hang of it. You can use it 3 ways. One is a treadmill (walking only), second a stair stepper, and third the treadclimber. It's a great piece of equipment. I have a picture on my page. It's a lot harder than it looks. It will make you sweat your tail off.
