Hand-held isokinetic-exercise ring

Abstract

The current invention is an isokinetic-exercise ring. Specifically, the invention is comprised of two rigid concentric rings. The inner ring is large enough to fit over a user's shoulders and/or waist. The outer ring is approximately 150% larger in diameter than the inner ring. The two rings are strapped together with elastic cord. A user grasps either inner or outer ring on opposite sides and pulses the invention in and out or in a twisting motion. Pulsing in turn causes the ring not being grasped to oscillate. Oscillation can be achieved in front of, above or around the user's body. By maintaining oscillation, the user will experience an isokinetic exercise.

1 . A method of exercising using an oscillating apparatus comprised of:
 two concentric rings strapped together with elastic cord, the smallest ring being large enough to fit around a user's shoulders and/or waist and the outer ring being approximately 150% larger in diameter,   grasping either concentric ring, and   rhythmically pulsing said ring in order to cause the other ring to oscillate in an opposite pulsing motion,   or rhythmically twisting said ring in order to cause the other ring to oscillate in an opposite twisting motion,   oscillating said apparatus while the apparatus is held before, above, beside or around the user,   
     
     
         2 . The method of exercising in  claim 1  wherein said concentric rings are strapped together with elastic cord. 
     
     
         3 . The method of exercising in  claim 1  wherein the inner concentric ring is large enough to fit around a user's waist and or shoulders. 
     
     
         4 . The method of exercising in  claim 1  wherein the outer concentric ring is approximately 150% larger in diameter than the inner ring.
