Named for their Mr Universe-winning, Predator-killing inventor, the rotating motion at the end of this exercise hits more than the standard press to fill out that V-shape.

Sit on a bench with dumbbells held in front of you, palms facing your shoulders as though you've just finished a bicep curl. Push the dumbbells up over your head while rotating your arms until your palms face away from you. Straighten your arms, pause, then reverse the movement.
