Abstract: An exercise device with a mat portion and one or more support assemblies. The mat portion defines a plurality of through holes. Each support assembly has a support member, a support bridge, and one or more support inserts. The support member has a flat bottom and a bolster-shaped top and defines one or more cavities that extend through the bottom of the support member and into the interior of the support member. The support inserts are generally hollow and are fitted into the cavities in the support member. The support bridge defines one or more projections that extend upwards from and generally perpendicular to the top of the support bridge. Each projection is sized and shaped to fit through one of the through-holes in the mat portion.

Abstract: The invention provides a kettlebell having a substantially hollow body and a curved handle, where the handle is integrally coupled to the body at two handle coupling locations proximate the top of the body. The handle defines a grip area in a location farthest from the body. The handle is tapered, with the widest part of the handle located proximate the handle coupling locations, and the narrowest part of the handle located in the grip area. The taper provides improved cross-sectional strength at the intersection of the handle and the body.

Abstract: A dumbbell retail/storage rack that has a first section with a bottom side that is designed to sit on a flat surface, and a top side that defines one or more dumbbell-receiving structures. Each of these structures has two spaced saddles for receiving the enlarged ends of a dumbbell. The retail/storage rack also has a second section that is integrally coupled to the first section and has a bottom that is essentially perpendicular to the bottom of the first section. This arrangement creates an “L”-shaped rack that can be placed on the bottom of either the first section or the second section, to display or to hold two or more dumbbells, as desired.
