ABSTRACT:
The invention is a semi-resilient exercise grip that has a non-resilient particulate core surrounded by a resilient rubber covering. Within the core there is also a dry lubricant such as talc that allows the particles to move over each other without damage. The outer covering may consist of a single thick latex layer, a thin latex layer surrounded by a thick rubber layer or a number of thin latex layers. The semi-resiliency of the grip enables a user to deform the grip and thereby change its shape. The grip can be moved within the hand to allow the user to deform it repeatedly while changing the grip's shape each time.
