Abstract: An isokinetic oscillation exercise device of an elongated flexible blade having a first and second end and a grip portion coupled to a middle portion of the elongated flexible blade. End caps coupled to said first and second ends adapted to storage. Further, a method is disclosed of manufacturing an isokinetic oscillation exercise device that provides a flexible elongated flexible blade, a grip portion injection molding, a pliable ring injection moldings, and end caps injection molding; slides the pliable rings on the elongated flexible blade separated by a length of the grip portion, overmolds a first-shot of the grip portion over the pliable rings, overmolds a second-shot of the grip portion to the first-shot of the grip portion to the elongated flexible blade, seals the first-shot to the second-shot of the grip portion against the pliable rings; and attaches the end caps to the elongated flexible blade.

Abstract: An isokinetic oscillating exercise apparatus which may be used to exercise different muscles by grasping by one hand or two hands centrally-located gripping portions attached to an elongated member and moving or shaking the member back and forth causing the opposite ends of the member to oscillate. The oscillation causes isokinetic exercising of a user's muscles. The gripping portions may be attached to the elongated member by adhesive or screws threaded into sleeves. Telescoping ends may be used to vary the length of the elongated member or the oscillating range of the member. The telescoping ends may be used to significantly reduce the overall length of the elongated member for ease in carrying the apparatus or for storage purposes. The telescoping ends may be small pipes which fit inside a large pipe, or flat elongated strips of metal that slidably engage brackets attached to a flat elongated member.
