Tennis Drill Demonstration
Players stand on the base line, with one player in front of another.
Player two (the player without the ball) has their back to their partner.
Player 1 can throw the ball when they like. As soon as player 2 sees the ball coming over their head they must react and move to catch it (preferably its second bounce) and then return to their partner in order to repeat.
Repeat 8 times before swapping.
Player 1 should not become rhythmic in their throwing as this will make things too easy for the catcher.
