Abstract
A skipping rope handle is formed in two connected parts which are biased apart by a spring. The end of the skipping rope is attached to a button which is rotatable within an end of the handle parts. The handle parts can be held in closed condition by moving a ring axially over the rebated end of the handle part, when the handle has a generally conventional form and use. When released by the ring, the handle can be used for exercising the gripping muscles of the hand by forcing the parts towards one another against the bias provided by the spring.
