A hockey athlete is shown here doing an underhand medicine ball rotational power throw. Notice she is disassociating her upper body from her hips as she throws, and again as she re-cocks through again. This exercise is effective for building core strength and rotational power. It is a great tool to put into a strength program, a power workout, or a conditioning circuit.
