I have one in my gym in my basement, unfortunately I do not use it much anymore cause I fear re-injuring my rotator cuffs.

I dont think my wrists would like me, definitely pretty punishing.

Upper body is pretty small though, if you can involve the whole body or at least the much larger lower body, then I'd say its easier to get the heart rate moving.

How about jumping rope up a 40 degree incline hill? ...one leg at a time? for a mile each leg?


Is that close?
