Self-mayofascial release, also known as "foam rolling", is a fancy way of saying self massage to release lactic acid from the muscles, relieving muscle tightness and soreness. Foam rolling can be useful in alleviating "trigger points" or "knots" in the muscles, or help reducing soreness from prior workouts and can get the muscles back to normal function more quickly. Foam Rolling is primarily done with a lightweight, affordable personal roll you can purchase from any sports store. The roll is used by allowing the person to apply direct pressure to sore spots in the body, promoting deep tissue massage and healing. Use the roll by laying across it and use the precise pressure to break up muscle knots and reestablish proper movement.
