Woman using the YFR on her quadriceps

Use your arms to lower the top of one or both of your thighs onto the YFR, and then roll from top to bottom of the quadriceps. You can adjust the angle of your leg in relation to the YFR to apply pressure the interior and exterior quadriceps. The more body weight you allow to rest on the YFR (i.e. the less weight you support with your arms and upper body), the more sensation your will create.
