A 12-minute sequence for a grumpy quadratus lumborum.
The quadratus lumborum (QL) is a hip hanger — a band of muscle between the top of your pelvis (iliac crest) and your lowest
rib (the 12th). It hurts because it is doing the glutes' and deep core's job: when those go quiet, the QL piggybacks
every bend, every breath, every side-step. This sequence stops loading it and wakes the muscles that should be doing the work.
Three phases, in order: (1) release & lengthen the QL, (2) wake the glutes and deep core,
(3) load them under mild effort. Stop short of pain at every step. This is not medical advice — if pain radiates down
the leg or comes with numbness or weakness, see a clinician. ~12 min
How to use
Phase 1 — Release & lengthen · ≈4 min
Cat–Cow → Supine Twist → Thread the Needle → Triangle → Sphinx — moves and stretches that un-grip the QL without loading it.
Phase 2 — Recruit the glutes & deep core · ≈4 min
Bridge → Single-Leg Bridge → Bird-Dog → Dead Bug → Locust — the muscles that should be doing the QL's job (glute max + medius, transverse abdominis, obliques, erectors), switched back on.
Phase 3 — Load the QL, controlled · ≈4 min
Side Plank → Warrior II → Warrior III → Chair — mild, upright load on the now-awake team. Short holds; the QL only speaks when it has to.
Phase 1 — Release & lengthen
Warm, quiet movement first. The QL is a gripper; today it learns to let go.
Phase 2 — Recruit the glutes & deep core
Wake the neighbors. If you feel the low back working harder than the glutes, slow down and re-set.
Phase 3 — Load the QL, controlled
Now the awake muscles carry load — side-bend capacity you keep, not strain you feel tomorrow.
How often, and how to progress
Run this 3–4×/week for 3–4 weeks. Consistency beats intensity here.
The rule: if a step reproduces the sharp or achey left-back flare, back off one level — fewer reps, shorter holds, or drop the phase-3 pose for that session — and hold that level for a week before trying again.
Progress Side Plank from knees to full only when the knee version is easy and pain-free. Both conditions, every time.
This is an endurance rebuild — short holds, frequent — not a max-strength project. Grind = flare. Frequent, easy = change.
Keep the daily movement habit from the sibling guides — desk-reset-programmer-sequence.html for chair bodies, targeted-strengthening.html for the general practice.
Why the left, always
Glute inhibition from sitting. Hours in a chair put the glutes to sleep; the QL inherits their hip-stabilizing job and never gives it back.
The QL is a breathing accessory. It fires on every breath to help lift the ribcage. With a weak deep core, it works all day — including while you sleep.
One fascia, many muscles. The thoracolumbar fascia is the meeting point of glute max, latissimus, and the erectors. Tension in any one of them drags on the QL.
Asymmetry and guarding. Everyone favors a side — crossing legs, leaning on one elbow, loading one hip — and after the first flare, guarding keeps the left braced even when you think you're relaxed.
For the press — a one-arm overhead press is a QL favorite: it loves to side-bend and fire to keep the bar stacked over your head. While this spot is grumpy, swap it:
bilaterally (both arms), seated with back support, or landmine press. Breathe out on the press, equal reps each side,
and stop the set the moment that spot talks. Revisit the single-arm version in a month or two.
