Patent ID: 8038585

Claim:
An isokinetic dynamic exercise device for use in exercise of the human body, the isokinetic exercise device having resistance to bending in any direction comprising: a flexible extruded thermoplastic elongated tube comprising a continuous interior cavity having two opposite ends, wherein said cavity has a diameter of at least 0.40 inches to no more than 1.0 inches and said interior cavity has a volume continuous between the opposite ends, wherein said flexible extruded thermoplastic elongated tube is sized to be held in a human hand during an exercise; a plurality of spherical weight particles within said interior cavity, wherein said plurality of weight particles occupy a portion of said volume of said interior cavity to partially fill said interior cavity of said flexible elongated tube, a closure on each of said opposite ends of said flexible extruded thermoplastic elongated tube; and said isokinetic dynamic exercise device has a length between said opposite ends of at least 10 inches to no more than 20 inches, wherein the partial filling of said flexible elongated tube permits said plurality of weight particles to move dynamically within said interior cavity in response to dynamic forces exerted upon said isokinetic dynamic exercise device by a user moving said isokinetic dynamic exercise device in a back and forth manner, and providing isokinetic dynamic action to said isokinetic dynamic exercise device and user during use of said isokinetic dynamic exercise device for exercise.
