The Shoulder-focussed Press Up is a variation on a Press Up that increases strength and stability in the shoulders and triceps.
Begin by setting yourself up with your feet on a bench and hands on the floor approximately 2 foot away from the bench and just wider than shoulder width apart. You should push your bum up into the air so that you form an upside down L-shape. From here, bring your head down to the floor, bending your arms, before pushing back up.
