ABSTRACT:
A tennis trainer includes a generally L-shaped arm having a ball holder at one end and pivotally engaged to a support at the other. Impact against the ball in a direction axially along the ball-supporting section of the arm is initially absorbed by a resilient section of the other section of the arm. A housing on the support includes a slot through which the arm extends and a rotatable cylinder to which the arm is secured. Bias springs oppose rotation of the cylinder and hence the arm. The housing is mountable upside down to permit the trainer to be used for back hand practice or for left handed fore hand practice. Various bending of the arm and vertical positioning of the support permits the ball to be positioned at various heights and positions.
