The Amazing Stickie likes exercises that serve multiple purposes. Medicine ball slams work the whole back of the body, demand coordination, and raise heart rate, all at the same time. For bonus points, on days when Stickie feels frustrated, she can imagine that the things that are frustrating her are in front of her on the floor and smash the heck out of them.
She begins holding the medicine ball over her head. Because medicine balls are not all that bouncy by nature, it requires a pretty good slam to get it to hit the floor and bounce back up to where it can be caught. Stickie uses her arms and back to slam the ball down and her knees to get low enough to catch it as it rebounds. She will often do thirty slams at a time, or, for a switch, slam the ball for a minute at a time between other exercises for a cardio burst.
