Abstract: An exercising device for strengthening hands or limbs has first and second bladders containing fluid with first and second valves that couple the bladders to a fluid pressure gage. Squeezing the first bladder by the left hand causes easy flow through the first valve to the pressure gage in a first direction, whereas the second valve presents a high impedance to flow in the same direction into the right hand bladder, so that the measured gage impulse pressure is proportional to the flow rate of fluid through the second valve indicating left hand strength. Squeezing the second bladder by the right hand produces fluid flow in the opposite direction with the right hand strength being measured in like manner. Alternate bladder squeezing creates a pleasant rhythmic exercise routine and the peak gage pressure indicates progress. The valve configuration enables strength measurement of the weak and the strong with one device.

Abstract: A hand grip for use in the self-exercise of hand, wrist and forearm muscles. A pair of pivot elements are mounted about a common pin for pivotal back and forth movement so that the head ends of the elements move together and apart. A force resistance elastomeric member having an interior cavity is releasably mounted on the head ends. Forces applied by the user in repetitively squeezing handles together cause the head ends to move apart against the yieldable resistance of the member. The member's elastic memory causes the elements to pivot back as the user releases his or her grip. A slot in the elastomeric member through which the head ends are mounted enables easy interchange between members of different elastic strengths to provide for a wide range of force resistances.
