ABSTRACT:
A variable resistance underwater exercising device for working the muscles of the upper body in a cool environment to stimulate generation of body heat. The device includes a support structure, a pair of support arms adjustably mounted on the support structure and a pair of disc assemblies adjustably mounted on the support structure and a pair of disc assemblies adjustably mounted on the support arms. Each of the disc assemblies includes a flat disc, a handle for manually rotating the disc thereby providing exercise to the upper body muscles, a plurality of flat blades carried by the disc and rotatable therewith to provide resistance to rotation in the water, a shroud assembly surrounding the blades and a gearing assembly for collectively varying the angular orientation of the blades with respect to the disc such that resistance of the water against the blades is adjustable to provide the desired drag on the discs as they are manually rotated under water by the user.
