ABSTRACT:
An exerciser includes a support for supporting the arm of a user and a hand grip pivotally coupled to the support. A tube is fixed to the support. Two discs are slidably disposed in the tube. A spring is biased between the discs. A cable connects the hand grip to a disc distal to the hand grip. The hand grip is moved away from the tube against the spring force for training the wrist portion. A bolt is rotatably disposed in the tube and is threadedly engaged with the disc close to the hand grip. The two discs are moved toward or away from each other for adjusting the biasing force of the spring.
