A training bat assembly for improving a user's swing of a baseball bat is provided. In one embodiment, the assembly includes a bat portion and a plug or cap portion, where the plug or cap portion is configured to mate with a distal end of the bat portion. For example, the bat may include a circular opening, and the plug may include a circular rod that is configured to fit within the opening. Alternatively, a cap with a circular opening can be used, where the cap is configured to fit over a distal end of the bat. By mating the plug or cap with the bat, and swinging the bat from a first position to a second position, the plug or cap is propelled from the bat, where the resulting location of the plug or cap can be used to determine the correctness of the user's swing was.

A tennis serve trainer mechanically encourages and causes the execution of a counter-intuitive hitting-up-on-the-ball service swing. The trainer has a straight shaft and a ball which can slide freely on the shaft between a tennis racquet grip on one end and a cap on the other. The ball is magnetically held against the grip until a threshold swing speed releases the ball. The magnetic force, the distance from the grip to the cap and the weight of the ball are coordinated so that the ball will strike the cap at the apex of the swing. At that moment, the arm is fully extended, the racquet head speed is accelerated to its maximum, the angle of attack is ideal, the ball and the racquet meet at the perfect impact point at the apex of the serve, and a snap in the racquet motion happens automatically at the top of the swing.
