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.
