HOW: Begin in a push up position. From here, lower down by bending your elbows and allowing your chest to come all the way down to the ground. Once your chest is resting comfortably on the ground, bring your hands up off the ground for a brief moment, return them to the ground and forcefully push back up into the starting position.
FEEL: You should feel your chest and core muscles working as you allow them to go through a slightly bigger range with the hand release.
COMPENSATION: Avoid arching through your back as you work in and out of the push up position. Maintain a strong and engaged core.
