Bring yourself to the ground and enter a high plank position with your hands directly under your shoulders and your legs extended directly behind you, with your feet hip width apart. Place a foam roller on the mat, perpendicular to your body and under your mid-shin. Maintaining a braced core and neutral spine, lift your left foot from the floor and lower your leg your left shin is resting on the foam roller with your foot turned out parallel to the floor. Keep your right foot firmly on the ground and slightly off to one side. This is your start position. Gently roll back and forth on the foam roller, feeling for any particular areas of tension in your lateral calf tendon. Repeat for the recommended amount of time before changing to the other side.
