How it works: Perform as many of the following touches as you're able to! The reps get increasingly more advanced, so adapt to the level of your athletes.
Use just the right hand fist to pop the ball up and down, staying as controlled as possible. After 20-30 reps, switch to the left fist. Then, alternate between the right and left fists. Bump with the right fist, then the left fist, then with your platform, and then perform a set. Catch the ball after every sequence. Perform the same sequence as described in #2, but perform a back set in front of a front set and catch it behind the back with both hands.
Requirements: Just a ball
