The next generation product that takes the classic pushup to the next level Professional Push Up Pro Perfect Pushup patented rotating handles allow your arms to move naturally, the same way they do when you throw a punch or press up a dumbbell. This helps engage more muscles in the arms, shoulders, chest, back and abs. Perfect Pushup maximizes strength building while helping to reduce joint strain. Made with built-to-last construction and padded grips for extra comfort. How The Perfect Pushup Works: The Perfect Pushup was invented by Alden Mills, a former US Navy SEAL and professional trainer. The Perfect Pushup basically takes a standard pushup bar — which keeps your wrists in a neutral, non-bent position — and attaches the pushup bar to a rotating base. This base allows you to maintain neutral wrist position while simultaneously rotating your arms (primarily at the wrist.) This ability to rotate is intended to allow you to compensate for your own bio-mechanics — taking stress off from the wrists and shoulders.It also allows you to simulate the compound motion of certain dumbbell chest press motions by allowing rotation at wrists, elbows and shoulders — something that is impossible with standard pushups. So if you’ve ever performed dumbbell chest presses with your palms facing forward and then rotated them to face each other at the top of the movement, you’ll know the motion I’m talking about.Perfect Pushup allows you to work your muscles more completely, more comfortably and more safely.
