A hand grip exercise device comprising an elongated enclosure having a cavity therein. The enclosure is of a size to be grasped and squeezed by a hand of the user. The enclosure has a peripheral wall which is resiliently deformable and which can be deformed radially inwardly. Resilient deformable material is provided in the cavity so that manual deformation of the peripheral wall radially inwardly resiliently deforms the material. This increases the squeezing force which the user must apply to the peripheral wall to deform it radially inwardly.
