Suzanne Somers was the spokeswoman for the Thighmaster piece of exercise equipment. The Thighmaster is an exercise product directly designed to shape one's thighs. The device is essentially two pieces of metal tube bent in a loop and connected with a hinge. The intended use is to put the Thighmaster between the knees and squeeze them together. This equipment exercises a person's hip adductors. It was mainly advertised in the 1990s by the actress Suzanne Somers.

The Thighmaster was invented in Sweden by a physical medicine intern (later "Dr.") Anne Marie Bennstrom (Prescott) as the "V-Bar" physical therapy device. In the USA, it later received the design patent number 343882S and was called a 'physical exerciser'. It achieved its strongest commercial success when it was marketed under the "Thighmaster" name.
