The handles are designed to rotate slightly during your push-ups, increasing muscle activation as you dip deeper. As a result, you can enhance your muscle strength and definition in your arms, shoulders, back, chest, and abdominal muscles. The handles also reduce strain on the joints in your wrists and elbows by allowing for natural body movements, while the ergonomic grips help distribute weight evenly and reduce pressure points. Thanks to the rugged profile of the handles, the Elite grips provide a secure grip on all types of surfaces.
