The ThighMaster is designed to tone the inner thigh.
The ThighMaster workout tool, which is now called ThighMaster Gold, was created by tobacco heir Joshua Reynolds, and made popular in the 1990s by marketer Peter Bieler and spokeswoman Suzanne Somers. This tool sold better when marketed as a thigh shaper, but it was originally created to work out the entire body and can be used in that way.
Target Thigh Muscles
The main exercise promoted with the ThighMaster provides resistance to tone the muscles of the thigh. It provides a transverse adduction movement that works the adductors, as well as the pectineus and the gracilis muscles, which are all located in the upper inner thigh. The ThighMaster can also target other muscles in the body if you use it in different ways than the original exercise.
Inner Thigh Exercise
To perform the original inner thigh exercise associated with the ThighMaster, sit in a chair and place the padded ends of the Thigh Master between your legs, just above the knees. The joint of the ThighMaster should be facing the floor. Use your thighs to press the ends of the tool toward each other and open your legs to go back to the starting position. Move slowly back and forth.
Warm Up First
Before you work out with the ThighMaster, warm up your muscles by performing the same movements at a lower intensity for 12 to 15 repetitions. For instance, you can perform the original ThighMaster leg movement without the tool, or use the tool, but don't push all the way in at first. Then, perform each exercise for one set of eight to 12 repetitions for a minimum of twice a week. Each resistance workout should include at least eight exercises.
Add Some Variety
If you steer away from the original intended use of this tool, you can work out additional areas of your body. To work out your chest, hold one arm of the ThighMaster against each forearm, with the joint at the top. Slowly press the arms of the device together with your elbows, slowly come back to the starting position and then repeat. You can work out the upper back if you hold one side of the ThighMaster against your right torso with your left hand, rest your right forearm on its other side, and press down with your right arm. Then, switch sides.
