Mark Ottobre leads a brutal shoulder finisher using partner resistance. You do rapid arm raises against his hands, hold at the top for five seconds, then push harder each round. Your shoulders will burn.
Raise your arms, raise your arms. Push against me as hard as you can. Harder, harder. Two, one. Good. Two in the pockets of my hands. Three. Try and keep the elbow straight. Four. There you go. Come on, up, up, up, up, up, up. Nice and high, nice and high, nice and high. Hold that position for five seconds. Five, four, three. Hold. Push against me, push against me. Five, four, three. Hard, hard, hard. Two. Come up all the way, all the way. Push. Raise, raise your arms, raise your arms, raise your arms. Go.
