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.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

An exercise apparatus for high intensity interval training includes a pair of elastomer tubing devices being stretchable beyond a resting length and further having a first end forming a hand grip for a user, and an opposing end including an anchor portion to enable releasable attachment to a fixed mount. The elastomer tubing devices are independently affixable to one or more fixed mounts at a first distance between the respective anchor portions along a transverse plane and a second distance above ground level to permit independent or tandem oscillation by the user, wherein the elastomer tubing devices are stretched a predetermined distance beyond the resting length and maintained approximately at the predetermined distance during the oscillation. Mechanical impedance of the elastomer tubing devices is adjustable by the user working against inertia generated during the oscillation.

An exercise apparatus that includes a shoe, a flexible elongated member and a motor assembly. The flexible elongated member is attached to the shoe at one position of a plurality of positions. The motor assembly is disposed between the shoe and the elongated member. The motor assembly is configured to cause the elongated member to oscillate.
