I've seen those advertised on TV. I can't help but to be concerned about the safety of it. How safe can it be with 2 conveyer belts moving under your feet while they are in addition, moving up and down at the same time.
I've seen it on TV. Rolling along and climbing at the same time?! LOL! I'm not a total klutz, but I know I'd fall off! Heck, if you use a stair climber, all you'd have to do is add walking to your routine, and you'd probably work the same muscles.
