The grip strength device is configured to gauge the grip strength of contracted muscles or aid in exercising particular muscles by providing resistance against the contracted muscles. The grip strength device is inserted into a user's vagina or held in a user's hand. The user either contracts the pubococcygeal or hand muscles depending on the casing used. The grip strength device has a removable casing containing a first fluid, a first bellows, a second bellows and a pressure gauge. The first bellows has a closed end and a first valve in communication with the casing. The second bellows has a second fluid. The second bellows has a second valve connected to the pressure gauge, and a closed end abutting the closed end of the first bellows. Pressure applied to the removable casing is communicated from the first bellows to the second bellows and measured by the pressure gauge.
