In this drill, the coach creates a narrow middle corridor from the baseline to the net using court markers. The players work cooperatively to keep the ball inside the corridor for as long as possible. Depending on the level of the players, the corridor width can easily be adjusted. This drill is ideal as a warm-up and rally drill for two to four players. The main focus is on accuracy, consistency, clean ball contact, rhythmic rallying and error reduction. At the same time, the game-based variations improve reaction skills, transition play and court awareness. Perfect for warm-up sessions, technical consistency training and rhythmic match preparation.
