Do you ever just want to throw something?

Not only is a Slam Ball fun to throw, done correctly, this exercise is a full body experience for Strength, Cardio and Core work. Here is a description of one version of a ball slam for proper technique.
Squat to pick up ball, bring ball overhead as you stand (possibly up on your toes), then thrust ball to the ground centered, forward, between your legs and follow through with your backswing arms- using your your core, arms and legs as you project lower to the ground to squat and pick up your ball again. Lighter weight balls may make for a faster tempo and allow you to focus on other things (like releases stress by just slamming for awhile), heavier weight balls can be more ballistic in nature.
