Forearm Exercise Device

Abstract

Herein described is an exercise device used to build strength in the wrist, arm, or forearm of the user. The device has two opposing grips and a tension means for generating resistance such that when the user rotates the grips the user works the muscles in the wrist, forearm, and arm. The device herein described may be portable or free standing. The exercise device furthermore contains a means for convenient and efficient adjustment of tension.

1 . A forearm exercise device comprising:
 a first grip assembly;   a second grip assembly;   a threaded rod;   a tension means;   the first and second grip assembly connected by threaded rod and tension means wherein counter rotation of first and second grip assemblies increases rotational tension of the device.   
     
     
         2 . The forearm exercise device of  claim 1 , wherein the threaded rod has a groove ratio of about 12 to about 20 grooves per inch. 
     
     
         3 . The forearm exercise device of  claim 1 , wherein the threaded rod has a groove ratio of about 16 grooves per inch. 
     
     
         4 . The forearm exercise device of  claim 1 , wherein the first and second washers are made of nylon. 
     
     
         5 . The forearm exercise device of  claim 1 , wherein the first and second washers are made of Teflon. 
     
     
         6 . A forearm exercise device comprising:
 a first grip and a second grip;   a first hub and a second hub;   a compression spring and a threaded rod wherein said threaded rod is inserted within said compression spring;   a first washer and a second washer, wherein said first washer and second washer engage the threaded rod and the compression spring at opposite ends.   
     
     
         7 . The forearm exercise device of  claim 6 , wherein the threaded rod has a groove ratio of about 12 to about 20 grooves per inch. 
     
     
         8 . The forearm exercise device of  claim 6 , wherein the threaded rod has a groove ratio of about 16 grooves per inch. 
     
     
         9 . The forearm exercise device of  claim 6 , wherein the first and second washers are made of nylon. 
     
     
         10 . The forearm exercise device of  claim 6 , wherein the first and second washers are made of Teflon. 
     
     
         11 . A forearm exercise device comprising: a stand up frame, a first pulley, a second pulley, a weight support, a first grip, a second grip, a drum, and a cord, wherein said cord is attached to the weight support, fed through the first and second pulleys, and wrapped around said drum such that rotation of first grip and second grip wraps the cord around said drum and elevates the weight support.
