Becoming a good basketball rebounder takes more than just height, and more than just a decent vertical jump - although they both help. But in the middle of a game, with the key crowded with large bodies, it's more important that a rebounder can take a hit and keep going up.
This drill conditions the inside player to keep going up for the rebound after being bumped and bounced around by opposing players.
Instructions to Players
Here's what players need to focus on:
This is a continuous drill - players do not rest at any time throughout, but continue to put the ball up, get the rebound, put the ball up - until the coach blows the whistle
Blockers need to be tough, but reasonable - the hits must be hard enough to simulate game contact, but not so hard that they knock the rebounder off his feet or cause injury
Rebounders need to use good rebounding fundamentals - jump high, grab the ball with two hands, take it down to chest level with two hands, back up to the basket with two hands - always protect the ball, keeping elbows out (but not swinging) so that opponents cannot reach around
Basketball Rebounding Drills: The Bump
The player begins just inside the block, with a ball; two other players stand on either side of him, each defensive player with a blocking pad (ask the football or rugby coach to loan you one; Amazon carries a good one as well - the Goalrilla Blocking Dummy for Restrained Contact Drills)
On the whistle, the player tosses the ball high on the backboard, on his side - so that the rebound comes back to him
The player then jumps high for the rebound, grabs the ball with two hands and takes it down under control
Immediately once the rebounder lands, the two blockers begin to hit him around the shoulders with the blockers, hard enough to shake his balance but not so hard as to injure him
The rebounder puts the ball back up hard; if he misses the shot, he rebounds and puts it back up again until he makes the basket
When the basket is made, the rebounder grabs the ball before it hits the ground and then tosses it off the backboard again, and everything starts over
The drill continues for 30 seconds, when the coach blows the whistle and players switch - one of the blockers becomes the rebounder, and the first rebounder becomes a blocker
Note that in order to maintain balance and power when he is rebounding and going back up with the shot, the rebounder needs to keep a slightly wider stance and lower his weight, and then explode into the jump as hard as he can
This is a tough drill with a lot of contact, and by the end of the 30 seconds, players should be quite tired. And well on their way to becoming better basketball rebounders.
