Stop Stretching Your Hamstrings To Fix Back Pain & Do This Instead

Quick Overview

The restriction causing low back pain and limiting hip mobility is often tight deep hip external rotators, not tight hamstrings, which can be addressed by performing a controlled squat to a box to encourage pelvic decompression and internal hip rotation.

Key Points: Low back pain and limited hip mobility are frequently misattributed to tight hamstrings when the actual issue is tight deep hip external rotators. Tight deep hip external rotators pull the pelvis into external rotation, which then limits the hips' ability to access internal rotation. A recommended corrective action is to decompress the back side of the pelvis by moving the pelvis from an externally rotated position toward a more internally rotated shape. A static stretch involves lying on your side in a 90/90 position with a foam roller between the knees and gently rolling front to back on the top side's pelvic bone for about one minute per side. A dynamic movement involves performing a box squat while holding a plate in front (plate reach) to encourage more opening and decompression of the hips' backside. When performing the box squat, aim for thighs parallel to the floor and maintain a stacked position of the head over the rib cage over the pelvis.

Context: The video addresses the common mistake people make when trying to relieve low back pain or improve hip flexibility by stretching their hamstrings. The presenter, using a pelvic model, explains that the underlying cause is often tightness in the deep hip external rotators, which are smaller muscles located deep on the backside of the pelvis that attach to the femur and sacrum/pelvis.

Detailed Analysis

The presenter argues that lower back pain and limited hip mobility are commonly misdiagnosed as hamstring tightness; instead, the issue lies with tight deep hip external rotators. These deep muscles, which attach to the back of the pelvis and the femur, pull the pelvis into external rotation when tight, severely limiting the range of motion needed for internal rotation, which is required for movements like touching your toes or performing a deep squat. To correct this, the goal is to decompress the pelvis and encourage internal rotation. The static solution involves lying on your side in a 90/90 hip and knee bent position, placing a foam roller between the knees, and gently rolling front-to-back directly on the top side's pelvic bone for about one minute per side, ensuring pressure stays off the muscle tissue itself. For a more dynamic approach, perform a plate-reach box squat: stand holding a weight plate extended forward, squat down until your thighs are parallel to the floor (or use a box/chair for assistance), and focus on creating more opening and decompression on the backside of the hips during the squat. Maintaining a stacked torso (head over ribs over pelvis) is crucial during this movement, and adding a slight heel elevation can help maintain optimal positioning.
