Aquatic neck exercise assembly

Claim 1

An aquatic helmet exercise assembly for use in exercising underwater to strengthen the user's neck muscles, comprising: a substantially rigid impact-resistant cap of water-impervious plastic for substantially covering the top, sides and back of the user's head; adjustable strap means for adjustably securing said cap to the user's neck and head; longitudinal substantially rigid water-engageable fin means of water-impervious plastic extending generally upwardly, forwardly and rearwardly of said cap along a generally symmetical axis of the user's body generally between the user's ears and in general alignment with the user's nose, said longitudinal fin means having a curved and arcuate outer edge and lateral facing, generally planar, substantially solid water-engageable surfaces for laterally engaging and deflecting the water and exerting hydrodynamic fluid resistive forces and torque on the user's neck as said longitudinal fin means is moved sideways in the water; and transverse, substantially rigid, water-engageable side fin means of water-impervious plastic extending generally upwardly and laterally ouwardly of said cap and positioned generally perpendicular to said longitudinal fin means along a transverse axis of the user's body in general alignment with the user's ears, said transverse side fin means cooperating with said longitudinal fin means to define generally cross-shaped fins as viewed from the top of the aquatic helmet exercise assembly, said transverse side fin means having a curved and arcuate outer edge, said transverse side fin means having a forwardly facing generally planar, substantially solid, water-engageable surface and a rearwardly facing, generally planar, substantially solid, water-engageable surface for engaging and deflecting water and exerting hydrodynamic fluid resistive forces and torque on the user's neck as said transverse side fin means is moved forwardly and backwardly, respectively, in the water.
