Abstract
The present invention is a hand and arm exercise device. The exercise device has a deformable elastic bulb having a central cavity. A first port is provided which communicates with the central cavity. A first check valve limits the flow through the first port such that a fluid can pass into but not out of the central cavity. A second port is provided which communicates with the central cavity, and with a chamber via a connecting passage therebetween. An adjustable bleed valve is provided in the passage. In one preferred embodiment the chamber is rigid, while in another preferred embodiment the chamber is elastic and a second check valve is provided in the second port to block flow into the central cavity of the deformable elastic bulb. It is further preferred that a pressure gauge be provided to the chamber so a user of the hand and arm exercise device can monitor his/her strength. The hand and arm exercise device is particularly well suited to exercises where it is beneficial to provide an isokinetic resistance against which the hand acts.
