PRESS-UP AND INVERTED SHOULDER PRESS
Targets: Shoulders, chest, core
(a) Get into a high plank position with your hands slightly wider than shoulder-width apart.
(b) Do a press-up, then push through your hands to straighten your arms while raising your hips and pressing into your heels.
(c) Bend your elbows to lower your head until it almost touches the floor. Next, straighten your arms, then return to the starting position. Struggling with this one? Ditch the press-up and inverted press every other rep.
