Abstract: An aquatic exercise boot is provided for interchangeable and comfortable use by men, women and children alike. The aquatic exercise boot permits a large range of movement and increased resistive forces, torque and torsion. The aquatic exercise boot serves as fluid resistors to water flow as the aquatic boot is moved through the water. The aquatic exercise boot can have internally padded aquatic foot, ankle, and leg assemblies with symmetrical Z-shaped fins. The aquatic foot, ankle, and leg assemblies can be pivotally connected to each other by vertical hinges and can be strapped, sewn, fastened, glued, or otherwise connected to a zippered elastomeric aquatic sock with an open toe portion.

Abstract: Aquatic exercise devices, such as in the form of an aquatic dumbbell, are provided for interchangeable and comfortable use by men, women and children alike. The aquatic exercise devices permit a large range of movement and increased resistive forces, torque and torsion. The aquatic exercise devices serve as fluid resistors to water flow as the devices are moved through the water. The aquatic dumbbell can have an array of axial fins and outer diverging transverse fins to provide enhanced strength building and hydrodynamic resistance.

Abstract: An aquatic exercise boot is provided for interchangeable and comfortable use by men, women and children alike. The aquatic exercise boot permits a large range of movement and increased resistive forces, torque and torsion. The aquatic exercise boot serves as fluid resistors to water flow as the aquatic boot is moved through the water. The aquatic exercise boot can have a ankle assembly with an expansion joint and pivotable side fins, a leg assembly with a calf-engaging clam shell and an aquatic leg section, and a foot assembly with an aquatic foot section and a curved aquatic sole.

Abstract: A hydrodynamic jumper which can be interchangeably used by men, women, and children alike in the water without substantial structural modification by simply adjusting its shoulder straps. The hydrodynamic jumper permits a large range of movement and controlled use of resistive forces. The hydrodynamic jumper includes an annular hydrodynamic member and shoulder straps which carry the annular hydrodynamic member about the waist of the user. In the illustrative embodiments, the annular member is semi-torroidal, trough-shaped or flat. The jumper can have blades, baffles, bumps, slits, or deflectors for increased hydrodynamic fluid resistance and pressure. The jumper can also have foldable hinged sections for compact storage, shipment, and handling.

Abstract: A hydrodynamic stroke builder has a specially configured aquatic hand section and forearm section with fins to progressively strengthen a person's arms, shoulders, chest and back. The hydrodynamic stroke builder can be interchangeably used by men, women and children alike and permits a wide range of movement with controlled amounts of fluid resistive forces, torque and torsion underwater. The stroke building consists of a hand engaging section which is either flat or convex and which has holes therein so that the user's fingers can readily grasp the hand engaging section. The forearm section conforms to the shape of the user's forearm and has V or U shaped fins extending therefrom to provide the proper resistance when the device is being used. The stroke builder can also include an upper arm section similar in design to the forearm section. The various sections are connected together by way of hinges.

Abstract: An aquatic helmet exercise assembly is provided which can be interchangeably used by men, women and children alike in the water without substantial modification by simply adjusting the chin straps. The aquatic helmet exercise assembly permits a large range of head movements and controlled use of fluid resistive forces for strengthening the neck, back and stomach muscles. The exercise assembly has upright fins and an optional rounded or pyramid-shaped crown.

Abstract: A hydrodynamic jumper is provided which can be interchangeably used by men, women and children alike in the water without substantial structural modification by simply adjusting its shoulder straps. The hydrodynamic jumper permits a large range of movement and controlled use of resistive forces. The hydrodynamic member includes an annular hydrodynamic member and shoulder straps which carry the annular hydrodynamic member about the waist of the user.

Abstract: An exercise assembly for use in water. The assembly has an elongated shaft supporting a plurality of fins at one end. During an exercise the user grips the shaft and forces the fins through the water which offers a resistance to movement of the fins.

Abstract: Aquatic exercise devices are provided which can be interchangeably used by men, women and children alike. The aquatic exercise devices permit a large range of movement and increased resistive forces, torque and torsion. The exercise devices can be in the form of leg exercise assemblies, such as an aquatic boot, with specially configured fins to strengthen muscles and enhance general muscular improvement. The device includes a boot comprising a lower leg section, an ankle section and foot section. Each of the sections has rearwardly extending inner fins and generally V shaped fins that extend outwardly from and which are attached to the inner fins. The device serves as a fluid resistor to water flow as the device is moved through the water.

Abstract: An exercise device which can be interchangeably used by men, women, and children alike, in the water, without substantial modification. The exercise device permits a large range of movement and increased control of resistant forces, torque and torsion. The exercise device includes a hydrodynamic resistance assembly which preferably is in the form of water-engageable blades or one or more apertured spherical shells each housing a rotatable apertured ball. The exercise device can be in the form of barbells, leg lifts, baseball bats, golf clubs, tennis racquets, etc., for strengthening the muscles used in particular sports, as well as for general muscular improvement.
