Abstract

A hand, wrist and forearm exercise device includes a resistive hand grip exerciser disposed at each end of a flexible, elongated resilient member. The flexible, elongated resilient member is arcuately bendable along a longitudinal axis and also one end is twistable relative to the another end along the longitudinal axis.

Claims (25)

1. A hand, wrist and forearm exercise device comprising:

a resistive hand grip exerciser disposed at each end of a flexible, elongated resilient member that is arcuately bendable along a longitudinal axis, and also one end is twistable relative to the another end along said longitudinal axis, said resilient member being a tension member.

2. The hand, wrist and forearm exercise device of claim 1 , wherein each said resistive hand grip exerciser comprises a bendable member and two hand engagement members extending from said bendable member.

3. The hand, wrist and forearm exercise device of claim 2 , wherein said bendable member is a torsion spring.

4. The hand, wrist and forearm exercise device of claim 2 , wherein each said hand engagement member includes a grip.

5. The hand, wrist and forearm exercise device of claim 4 , wherein each grip is formed of a covering material.

6. The hand, wrist and forearm exercise device of claim 1 , wherein said resistive hand grip exercisers and said resilient member have resilient portions that are of a one-piece integral construction.

7. The hand, wrist and forearm exercise device of claim 6 , wherein said resistive hand grip exercisers and said resilient member are formed of a metal material.

8. The hand, wrist and forearm exercise device of claim 6 , wherein said resistive hand grip exercisers and said resilient member are formed of a polymer material.

9. The hand, wrist and forearm exercise device of claim 1 , wherein the device is an assembly of individual components.

10. The hand, wrist and forearm exercise device of claim 9 , wherein said resistive hand grip exercisers are connected to said resilient member by fasteners.

11. The hand, wrist and forearm exercise device of claim 1 , wherein said resistive hand grip exercisers are pivotable relative to said resilient member to fold the device into a compact storage disposition.

12. The hand, wrist and forearm exercise device of claim 11 , including a detent locking assembly releaseably locking each resistive hand grip exerciser in an open use disposition and also the compact storage disposition.

13. A method of exercising hand, wrist and forearm muscles, the method comprising the steps of:

providing the hand, wrist and forearm exercise device of claim 1 ;

grasping said resistive hand grip exercisers, one in each hand; and

repetitively deforming said resilient member into an arcuate shape, wherein a spring force of said resilient member exercises forearm muscles.

14. A method of exercising hand, wrist and forearm muscles, the method comprising the steps of:

providing the hand, wrist and forearm exercise device of claim 1 ;

grasping said hand engagement members of said resistive hand grip exercisers, with one hand on one said resistive hand grip exerciser and another hand on the other said resistive hand grip exerciser; and

urging said hand engagement members of each resistive hand grip exerciser toward one another, wherein a resistive force of said resistive hand grip exercisers exercises hand and forearm muscles.

15. A method of exercising hand, wrist and forearm muscles, the method comprising the steps of:

providing the hand, wrist and forearm exercise device of claim 1 ;

engaging said hand engagement members of one said resistive hand grip exerciser with one hand, and engaging said hand engagement members of the other said resistive hand grip exerciser with another hand; and

flexing one wrist while extending the other wrist counter rotationally relative to said resilient member, and then extending said one wrist while flexing said other wrist, wherein a resistive force of said resilient member exercises wrist and forearm muscles.
