First Claim
1. An exercising device for strengthening body members comprising:
- (a) first and second deflectable vessels for containing fluid therein;
(b) first valve means, fluid coupled to said first deflectable vessel, having a low fluid impedance for fluid flow out of said first deflectable vessel in a first direction and a high fluid impedance for fluid flow in a second direction opposite said first direction;
(c) second valve means, fluid coupled to said second deflectable vessel, having a low fluid impedance for fluid flow out of said second deflectable vessel in said second direction opposite said first direction, and a high fluid impedance for fluid flow in said first direction; and
(d) fluid pressure measuring means, fluid coupled between said first and second valve means, for measuring fluid impulse pressure produced by alternate deflection of said first and second deflectable vessels in turn produced by motion of said body members.

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.
