  • Weighted swing training apparatus
    Patent number: 8968119
    Abstract: A weight apparatus is provided. The apparatus may be attached to a sports device, such as a baseball bat or other device which may be swung by a user. In one configuration, the apparatus has a body portion that at least partially surrounds a portion of the swingable device. As an example, the body portion may act as a sleeve surrounding an end of the device opposite the end of the device which is gripped by the user. The apparatus also has a weighted portion, which is coupled to the body portion. The weighted portion is disposed at least partially adjacent an end of the swingable device. In certain configurations the apparatus has a center of balance between a midpoint and one end of the apparatus. In certain cases, the weighted portion distributes weight closer to a distal end of the swingable device, in order to assist a user in warming up or otherwise training with the device.
