Lie on your left side on an exercise mat with your left leg extended and propping your torso up on your left forearm. Bend your right knee and place your right foot resting flat on mat directly in front of you left leg. Place a foam roller perpendicular to your body under the middle of your thigh. Your left hand should be resting on the mat just in front of you. This is your start position. Gently roll back and forth on the foam roller, feeling for any particular areas of tension in your outer thigh (or IT Band) and using your arms to help you roll back and forth. Repeat for the recommended amount of time before changing to the other side.
