Stand about 2 meters from the basket.
Toss the ball up to the rim simulate a shot.
Jump and rebound the ball.
Outlet the ball to a wall or a toss bag.
Do this drill 10 times.
Ensure the toss hits the rim and not the backboard to accurately simulate a shot.
Each time get good rebounding position, knees bent, back bent, elbows up, hands open and palms down.
Chin the ball every time and your elbows are up.
Rebounding is the least glamorous thing in basketball and one of the most decisive. It is also almost entirely a habit, which means it is entirely coachable.
Good spacing is only the start. The best modern offences teach players to attack the defence's rotations and play in a permanent 4-on-3 - here is how to coach that read.
The ball screen produces almost half of all professional offensive possessions, yet most teams still teach it as a memorised play. The modern approach trains the read - giving players a framework to decide based on what the defence does, not what the coach called.
