The 4-3-2-1-0 Drill is a very simple, yet easy drill to utilize for your players. It is great for all ages, while providing a challenge in completing the full cycle without making a mistake. This is one of those drills where the player is working on their hand speed and coordination, without even knowing it since its a challenge.
You can watch Jayden (8 years old) perform the drill below.
After each number of side to side crossovers (start with 4), move the ball between the legs and behind the back/2 step crossover/rocker. Then repeat side to side crossover side to side (move to 3 of them), then repeat with between the legs and behind the back/2 step crossover/rocker. Then move to 2 side to side crossovers and continue till you get to zero.
