The Perfect Pushup consists of two rotating handles that are supposed to allow natural movement of the shoulder. The Perfect Pushup is advertised as increasing activation of the chest, shoulders and back muscles while taking pressure off the wrist, elbow and shoulder joints. The mechanics of a pushup performed using the Perfect Pushup are different from regular pushups and may not be appropriate for everyone. Take special care if you have a shoulder problem or think you are at risk for one.
Range of Motion
The Perfect Pushup allows you to lower your body farther than a regular pushup because the handles are elevated. While the deeper range of motion may improve muscle activation in some positions, lowering your body below your hands puts unnecessary stress on the shoulder and may overstretch your muscles. For some, repeating this motion may aggravate an existing shoulder problem or contribute to a new one. Consider switching to a close grip or putting a pillow under your chest to keep you from going too low.
Instability
Rotation of the Perfect Pushup handles introduces instability to the shoulder joint. Instability makes the exercise more challenging but may increase your risk of injury. While instability may not be an issue for people with healthy and strong shoulders, those with a pre-existing condition or shoulder weakness should consult a doctor before using the Perfect Pushup.
Rotator Cuff
Strong rotator cuff muscles will help keep your shoulders safe and avoid injury. The rotator cuff is a group of four muscles that are responsible for keeping the head of your arm bone safely fixed inside the shoulder socket. Consider adding several weeks of rotator cuff strengthening to your routine before using the Perfect Pushup.
Core
Your core strength affects the integrity and safety of your shoulder joint during a pushup. Advanced pushup variations, such as the Perfect Pushup, shouldn't be attempted until your core is strong enough. Consider performing an easier exercise if your hips are sagging toward the floor or your back is arching.
