Abstract
A finger and hand exerciser includes a housing defining four chambers arranged side-by-side in parallel with one another. Each chamber receives a tension adjustment member, a plunger that is reciprocatingly slidable in the chamber, and a helically wound compression spring extending between the plunger and the tension adjustment member. Each tension adjustment member includes a knurled wheel which the user of the finger and hand exerciser may turn to decrease or increase the force the spring exerts on the plunger.
