Abstract: A heavy bag uses one or more removable canisters placed inside a cover, substantially filling the cover and thereby forming a modular construction for the heavy bag. The cover has a selectively resealable closure which permits the canister or canisters to be inserted into or removed from the cover. The bag is formed from a set of the canisters within the cover. In one embodiment of the invention, the canisters are not all filled with the same stuffing material, causing the densities or hardnesses of the canisters to differ from each other, thereby creating zones of differing hardnesses within the bag. The canisters are preferably filled with stuffing material in the form of sand, pieces of rag, liquid, gel, foam, or egg-crate foam. The invention can include a structure to avoid separation of opposing surfaces of adjacent canisters received in the cover of the bag.

Abstract: An applicator stores a boxer's hand wrap substantially without folds, creases, or wrinkles, all of which are especially severe if the hand wrap is relatively stiff with dried perspiration. By storing the hand wrap in a smooth, rolled configuration, it can be readily reapplied in a similarly smooth, non-wrinkled manner, as is optimal for boxing purposes. The applicator has a spool and outwardly extending spindles. The spool is non-rotatable relative to the spindle, permitting the wrap to be appropriately tensioned while it is being applied to the boxer's hand. The applicator has deodorant which permeates the wrap when it is stored on a receiving surface of the spool.

Abstract: A mount for securing a punching bag or other exercise equipment to a support structure has a helical spring nested around a rotatable, slidable rod. The resulting structure relieves torsional stresses and absorbs longitudinal forces experienced by the punching bag or other exercise equipment during its use, thus prolonging the life of such bag or equipment. The nested or non-serial connection of elements in the mount shortens the operative length of the mount, which is advantageous when the vertical mounting location for the bag or equipment is limited, such as by the presence of a standard ceiling.
