Eliminate unnecessary strain and get the ultimate upper body workout with the Extreme Push-up Grips by Sportcraft! Made with rubberized comfort grips, a non-slip base, and steel ball bearings for smooth rotation, these muscle-building marvels provide natural downward motion during push-ups. This more efficient motion reduces injury and allows you to target chest, arm, shoulder, back and abs. Get the portable, powerful push-up today!
