Place 3 cones one on the free throw line and the other two next to it on the right and left side about a metre and a half away from the central cone.
Start from the right cone do a right hand layup grab your rebound and then circle around the central cone and do another right handed layup garb the rebound again and circle around the cone on the left side this time doing a left handed layup grab the rebound and circle around the central cone again doing another left handed layup then circle around the right cone and repeat until you have made 15 layups all together
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.
