yeah same stuff, lifting weight and the inverse, one flip of a knob and your being strethed like hell.. they still measure the radius, and every point of extension or retraction is tough to get. they still use the straps, where you loop it over your foot and pull over your shoulder until your foot touches your lower back.. the stretching hurts more than the resistance lifting, bike, et.
but the quad stim and ice at the end feels so good you want to have a cigarette with it
