Abstract: The subject matter is a finger exerciser. The finger exerciser comprises a base and an upright support which is movable on the base. On the upright support there is a rotatable pointer. There is a scale to indicate the degree of movement of the pointer. There is a variable tensioning means operatively connecting with the pointer. This variable tensioning means can be rubber bands. There is a hand rest. A person can place the hand on the hand rest and in one version a person can retract the finger so as to move the pointer. In another version, the person can extend the finger so as to move the pointer. The upright support is moveable on the base. This provides a variable distance between the hand rest and rotatable pointer to accommodate hands of different sizes and fingers of different lengths. The force required to move the pointer can be varied by the use of different rubber bands and by the use of a multiplicity of rubber bands to make it more difficult or less difficult to rotate the pointer.

Abstract: A stomach muscle monitoring/warning device includes a belt housing with a slide plate that moves a pin into contact with a flexible sounding spring inside the belt housing to mechanically produce a subtle audible clicking sound when the stomach muscles are expanded beyond a preset limit for warning the user to retract the stomach muscles to improve posture.
