Foam Rolling
Foam rolling is a self-myofascial release (SMR) technique that is used by athletes and physical therapists to inhibit overactive muscles. This form of stretching utilizes the concept of autogenic inhibition to improve soft tissue extensibility, thus relaxing the muscle and allowing the activation of the antagonist muscle.
This technique can be effective for many muscles, including: gastrocnemius, latissimus dorsi, piriformis, adductors, quadriceps, hamstrings, hip flexors, thoracic spine (trapezius and rhomboids), and TFL. It is accomplished by rolling the foam roller under each muscle group until a tender area is found, and maintaining pressure on the tender areas (known as trigger points) for 30 to 60 seconds.
