Setup
- Lie on your side with the foam roller positioned just below the knee of your bottom leg.
- Support your upper body on your forearm and place your top foot flat on the floor in front of your bottom leg for balance.
- Keep the bottom leg straight and ensure the lateral (outer) side of the calf is resting on the roller.
How to do it
- Use your arms and top leg to slowly shift your body, rolling the foam roller down toward your ankle.
- Inhale as you move the roller toward the ankle and exhale as you roll back up toward the knee.
- Maintain a slow, steady tempo, spending extra time on any tender 'trigger points' you encounter.
Form checklist
- Avoid rolling directly over the knee joint or the ankle bone.
- Keep the bottom leg relaxed to allow for deeper tissue penetration.
- Maintain a strong, stable shoulder on the supporting arm to protect the rotator cuff.
- Ensure you are on the fleshy side of the leg, not the shin bone (tibia).
Pro tips
- While paused on a tender spot, perform ankle circles or point and flex your toes to enhance the myofascial release.
- Slightly tilt your hips forward or backward to find the exact line of tension in the peroneal group.
Make it harder
- Stack your top leg directly on top of the bottom leg to increase the total body weight applied to the roller.
- Switch to a high-density foam roller or a lacrosse ball for more intense, localized pressure.
