Zusammenfassung:The tennis trainer has a pendulum arm(7) mounted on a stand (2) to pivot about a pendulum axis (6) and provided at the free end with a rotational element (10) simulating a tennis ball with a spring-elastic or tennis ball like surface to be set in rotation when hit by a racket (20). When the racket hits the ball the arm pivots out from a starting position into a rotational direction and then automatically returns to the starting position. The pendulum axis can be adjusted in height. The pendulum pivots out up to a stop (17) which can be vertically and or horizontally adjusted.
