A hinged vaginal strengthening device has three points of resistance along its length, which correspond with the three layers of pelvic musculature. The device is inserted into a vagina and compressed by the pelvic floor musculature, in accordance with various regimens to achieve goals such as decreasing vaginal gap or overcoming painful intercourse. The device can be of various dimensions, and various compression resiliencies thereby allowing a user to progress through multiple steps to achieve their goal of increasing or decreasing their vaginal space, as well as increasing muscle tone.
