Piriformis stretch on foam roller
The piriformis muscle is a deep muscle located beneath the gluteal (butt) muscles. The piriformis muscle laterally rotates and
stabilizes the hip.
This muscle is important for athletes who participate in running sports that require sudden changes of direction.
The piriformis works along with other hip rotators to turn the hips and upper leg outward (external rotation of the hip).
Strong and flexible hip rotators keep hip and knee joints properly aligned during activity and help prevent sudden twisting of the
knee during quick side-to-side movements, quick turns, lunges or squats.
