Developed by a former Navy SEAL Platoon Commander, Perfect Pushup uses the latest advances in biomechanics and engineering to power your push up. Unique rotation handles and a ball bearing design let your arms rotate naturally, like when you throw a punch or press up a dumb bell. With every Perfect Pushup you engage more muscles in the arms, chest, shoulders, and back to accelerate the results you want'ripped abs, a chiseled chest and rock hard biceps and triceps.
