Perfect Pushup inventor and U.S. Navy SEAL, Alden Mills learned during his SEAL training, the more that exercises simulate the natural movement patterns of muscles and joints, the better the results and the less strain is put on the body. The Perfect Pushup’s rotating hand grips allow your arms to rotate during a pushup the same way they naturally twist when you throw a punch or press up a dumb bell. This works more muscles and reduces strain on your joints – maximizing your workout. The Perfect Push Up is the ultimate piece of Push Up Equipment.
