Perfect Pushups, devices that make pushups more effective and less stressful on your body. Created by a former Navy Seal, Perfect Pushups have rotating hand grips that allow your arms to twist naturally during pushups. This means more comfortable pushups, less stress on your wrists and elbows, and full engagement of your rotator cuffs and scapular muscles. The large non-skid bases work on both carpet and hard floors.
