How to Stretch the Quadratus Lumborum

If you've ever had low back pain, you might have tight quadratus lumborum muscles. These large muscles are on each side of your low back, running from your ribs to your pelvis. Each muscle bends your upper body toward the side they're located on. When they work together, they bend your low back backward.

The quadratus lumborum can be stretched in many positions -- standing, sitting and lying down. When stretching in any of these positions, do not stretch to the point of pain.

The quadratus lumborum muscles can be stretched simultaneously with a standing low back stretch.

Step 1

Stand with your feet approximately three feet apart. Turn your toes out slightly.

Keeping your knees straight, bend forward at your hips as far as possible. Slowly allow your low back to bend until you feel a strong but comfortable stretch. Hold for 20 to 30 seconds and repeat three times.

Step 3

To increase the amount of stretch, cross you forearms over each other and dangle your arms over your head while you are bent over.
