the invention is a resilient exercise grip that has a non - resilient core with a doughy consistency surrounded by an elastic covering . the core consists of a powdery substance , a liquid , a preservative and also contains low - density beads to create a lighter grip . the outer covering may consist of a single thick layer , or a number of thin layers . the resiliency of the grip enables a user to deform the grip and thereby change its shape which quickly and substantially returns to its pre - deformed state .
