The ARX Is the first of its kind — a computer-controlled, motorized exercise technology that provides the most effective, efficient, and quantified workout — the ideal way to practice the super slow, super heavy, strength training protocol to build maximum muscle in minimum time, as safely as possible. This is because the ARX instantly and automatically adjusts to the changing level of force you are producing — you are never “holding” a weight that is too much. ARX is the best way to safely rehab after injury and maintain muscle mass and bone density as we age. And since every second of each rep is quantified, you can track your results week over week, month over month. Use ARX now in NYC @ PRTL.
