Abstract
A wrist exercise device includes a hollow shaft which houses a pair of compression springs. Tension disks are provided at the remote ends of the springs. The disks are moved toward and away from each other by turning a tension knob at one end of the device to increase or decrease the resistance from a pair of friction pads on each side of a handle at each end of the device. A resistance indicator is provided at one end of the device.
