A sports training device comprises a substantially vertical standard with a suitable ball at the top for practicing sports such as baseball or tennis or a bent over standard with a ball close to the ground for practicing sports such as golf. The ball is attached to an arm that is, in turn, attached to a pivot and a spring both on the standard. Striking the ball in the normal manner for the particular sport causes the ball to move away from the bat, racket or club until clear. The ball then returns under the influence of the spring and oscillates about the starting location of the ball. Depending on spring tension and damping effects of the arm, spring and standard, the ball will become stationary very quickly or continue to oscillate widely. For some sports, heavy damping is preferred. For other sports, light damping may be preferred.
