We studied the motions of the human body and created a natural exercise motion that allows your body to generate maximum power output. This synchronized motion allows your left arm and left leg to pull at the same time your right arm and right leg are pushing and vise versa as you reciprocate the motion. To optimize efficiency, we made the motion adjustable from a near vertical climb to a near horizontal crawl and everything in between. This patented breakthrough technology simultaneously engages more muscles, creates greater blood flow and burns calories at a faster rate than any other exercise machine.
