WHAT IT’S REALLY ABOUT
Back Pain, CrossFit, And The Science Of A Resilient Spine
- Dr. Stuart McGill explains why back pain is so prevalent, especially among active people, emphasizing poor movement patterns, sedentary lifestyles, and untargeted training or rehab.
- He details how specific mechanical causes (like endplate fractures, Schmorl’s nodes, and disc bulges) arise from chronic loading patterns, particularly in sports such as CrossFit and powerlifting, and why recovery requires precise assessment and tailored programming.
- McGill introduces his ‘Big Three’ core exercises as low‑risk, high‑reward tools to restore spinal stability, enhance performance via proximal stiffness, and reduce pain—while warning against indiscriminate stretching and overtraining.
- The episode is anchored by the story behind the book ‘Gift of Injury,’ where world‑class powerlifter Brian Carroll rebuilt an apparently “obliterated” spine to world‑record performance, illustrating how disciplined mechanics, loading, and mindset can reverse even severe back injury.
IDEAS WORTH REMEMBERING
5 ideasStart with a precise mechanical assessment, not the MRI image.
McGill always evaluates the person, their history, and pain triggers before looking at imaging, because MRIs show anatomy (wounds and old scars) but only a good clinical assessment reveals which structures are actually causing current pain.
Chronic loading patterns, not single events, usually create back injuries.
Endplate fractures, Schmorl’s nodes, and disc bulges commonly arise from repeated heavy loading and loaded spinal flexion (e.g., heavy deadlifts plus high‑rep flexion in CrossFit), gradually degrading collagen and joint integrity.
Sedentary work plus “blowout” training is a potent recipe for back pain.
Long hours sitting stiffen hips and alter spinal mechanics; trying to undo this with one intense daily gym session often overloads deconditioned tissues and encourages treating the spine like a ball‑and‑socket joint when it is not.
Spinal health depends on moving well and moving often—not one perfect posture.
There is no single ideal posture; the best posture is one that changes frequently to move stress around the body, combined with skillful movement strategies that avoid high stress concentrations in vulnerable structures.
The Big Three build proximal stability that both reduces pain and boosts performance.
The curl‑up, side plank, and bird dog were chosen because they maximize spinal stability with minimal load; they dampen painful micro‑movements and create residual neural stiffness, which can immediately relieve pain and increase striking, running, and lifting performance.
WORDS WORTH SAVING
5 quotesVery few people these days get a competent and thorough assessment of the mechanism of their back pain.
— Dr. Stuart McGill
The ideal posture is one that frequently changes, because you migrate stress concentrations in your body through posture change.
— Dr. Stuart McGill
CrossFit combines adaptations to stimulate mobility, and then the next exercise is asking you to have a tougher collagen. That’s very, very difficult to do in terms of biological adaptations.

Have you built a world champion powerlifter? Do you know one with loose hamstrings? They don’t exist.

Just because the pain is gone one day, it doesn’t mean their back is healed.
