Player will bend at the back whilst reaching down trying to touch their toes. The player will slowly fall forward till their hands touch the ground. Once their hands have touched the ground they will walk their hands forward until they are in a push-up position.
From this position they will walk their feet forward keeping the knees locked out in order to stretch the calf muscles.
Once they have stood up, they will continue the stretch doing the same series again.
This stretch should be done 4/5 times.
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.
