Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.

The present application discloses an accessory for items of sporting equipment. Implementations may provide an accessory comprising a structure configured to be affixed to a first end of an item of sporting equipment meant to be swung or rotated, such as a baseball bat, lacrosse stick, or tennis racquet. The addition of the accessory results in movement of the center of mass of the sporting item. Implementations may be varied in weight and dimension such that the center of mass of the sporting item is moved to a location optimal for the demands of the sport and individual athletes' needs. Implementations may also provide for modifiable weight or dimension of the accessory.

A training weight for a sport stick is provided. The sport stick includes a housing having a sidewall, a proximal end wall and a distal end wall. The sidewall and proximal end wall include an opening and slot which are sized to accept a sport stick's handle and knob. Preferably, the training weight includes a cup which is biased by a spring to force the sport stick's knob to engage and lock to the training weight's proximal end wall. The training weight may include a cam mechanism to permit the retraction and extension of the spring and cup.
