Exercise 1: Players take turns throwing the ball, player in the backfield plays the ball back underhand.
Exercise 2: First ball comes deep (BH return), 2nd ball comes short (OH return) - must be catchable!
Exercise 3: Throwers stand a little further apart and throw straight: player with ball on the sideline throws deep, other short (not catchable)
Exercise 4: player with ball on the sideline does an intermediate test and then gives a deep ball, player in the field takes this ball OH and plays it to player B at the net. Player B can then immediately return a ball on the 3-meter line or test the ball to the player on the sideline and then the exercise starts again.
