<p>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 resisive forces, torque and torsion. The aquatic exercies 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.</p> |
