Abstract: The invention described in the specification relates to a heavy bag for use in training a boxer and to a method for filling the bag. The bag has a substantially cylindrical outer shell made from a fabric-like material, the shell having closed ends. A shredded rubber material fills the bag and provides the bag with sufficient weight for punching and sparring training activities. Use of the shredded rubber material to fill the bag not only permits significant improvement in the bag filling operation but also provides increased durability, improved impact absorbing characteristics and less permanent deformation of the bag during use.

Abstract: The invention described in the specification relates to the art of fitness training and in particular to a training bag apparatus which comprises a training bag support base having a planar, substantially circular bottom portion, a dome-shaped upper portion attached to the bottom portion defining a substantially closed cavity therebetween. The upper portion having a dome-shaped outer surface contains a centrally positioned support collar attached thereto and at least two support ribs radiating from the support collar along at least a portion of the outer surface of the upper portion. The support collar and ribs are integrally molded with the upper portion. The base further includes a centrally positioned upstanding projection attached to the bottom portion and a substantially rigid elongate tube removably fitted over the upstanding projection and extending at least from the bottom projection to the support collar.

Abstract: The apparatus described in the specification comprises a golf stoke training apparatus for developing muscle memory relative to a golf stroke. The apparatus includes a flexible strap having a shoulder portion, a first arm portion and attachment device for attaching the first arm portion to a golfer's arm and a second arm portion and finger strap for attaching the second arm portion to a golfer's hand in order to maintain the golfer's wrist in a flexed position during the golf stroke. The device is relatively simple, inexpensive to manufacture and substantially maintains the golfer's arms and shoulders in a fixed position relative to one another throughout the golf swing so that muscle memory is developed in the golfer relative to the stroke.
