The players are lined up behind each other in front of a wall. The distance to the wall must be about 3-4 meters. The front player has a ball.
The ball is thrown against the wall and the front player jumps with legs far apart over the ball when it returns. The next player in the line moves forward, catches the ball and throws it against the wall..... The first player moves behind the line.
This exercises can be made as a competition, in which the player, who does not jump over the ball or is unable to catch the ball leaves the line.
