Hi Matthew. I love this question since I do a lot of power development work with my athlete clients. I responded to a similar question with these responses:
Squats with MB backwards toss
Fast Squats with OH Press (tube)
All of the Olympic Lifts
Any exercise involving “releasing” the weight (think of weighted throws)
Although you really didn’t ask the question, the prerequisite to establishing power is establishing strength. Develop a good base of strength first and the power work will be more effective and less prone to injury.
