Boxing out is a basketball technique used to gain position for a rebound after a missed shot. When a player anticipates a shot, they position themselves between their opponent and the basket. By using their body to create space, they can effectively block the other player from getting to the ball. To box out effectively, a player should bend their knees and maintain a low center of gravity. They should also keep their arms extended to secure the rebound once the ball comes off the rim. This technique is crucial for teams to control possession and create scoring opportunities.
