## Abstract

A flexible ring is disclosed comprising one or more coiled springs and/or polymeric ring(s). In some embodiments, the coiled spring envelopes one or more inner coiled springs. In other embodiments, one or more handles circumscribe a portion of the outer coiled spring. Various embodiments of the present invention substitute flexible polymeric members for the coiled spring. In other embodiments, a disc is substituted for the polymeric ring(s).

## Claims

### Claim 1

A handheld exercise device comprising:
one or more coiled springs forming a ring of 4 inches to 26 inches in diameter; and
two sheaths circumscribing the one or more coiled springs, the sheaths forming handles affixed to the ring, the handles disposed about the ring such the handles are diametrically opposed about the ring;
wherein the handles are torqued in orthogonally opposed directions forcing the exercise device out of its ring shape.

### Claim 2 (depends on 1)

The isotonic exercise device of claim 1, wherein the ring is twisted, and not stretched, by a user to strengthen muscles and tendons in the wrist, hand, forearm, and shoulders.

### Claim 3 (depends on 1)

The isotonic exercise device of claim 1, wherein the handles comprise a sheath circumscribing the ring.

### Claim 4 (depends on 1)

The isotonic exercise device of claim 1, further comprises a second coiled spring disposed within the coiled springs to increase resistance.

### Claim 5

A handheld exercise device comprising:
two collinear connected coiled springs of equal length forming one ring of 4 inches to 26 inches in diameter; and
two handles affixed to the ring over connection points between the springs, each handle defining a hollow recess with two open ends for receiving the ring, the handles diametrically opposed about the ring;
wherein the handles are torqued in orthogonally opposed directions forcing the exercise device out of its ring shape.

### Claim 6 (depends on 5)

The handheld exercise device of claim 5, wherein the ring is twisted by a user to strengthen muscles and tendons in the wrist, hand, forearm, and shoulders.
