Coach: hips cause low‑back pain

A mobility coach says recurring lower-back tightness often starts with stiff hips, not the spine, and she built a five-move routine around that idea. (tomsguide.com) Tom’s Guide published the routine on April 13, 2026, and identified the coach as Sam, a trainer with coaching experience at F45 and Virgin Active. The article also said she has completed two mixed-doubles HYROX competitions. (tomsguide.com, tomsguide.com) The premise is mechanical: when the hips stop moving well, the lower back can start doing extra work during bending, standing and rotation. Harvard Health says the main hip flexor muscles attach to the pelvis and lower back, and prolonged sitting can tighten and shorten them. (health.harvard.edu) Harvard Health says that tightness can make pelvic rotation harder and “may contribute” to low-back pain. That does not mean every sore back is a hip problem, but it explains why coaches and physical therapists often look at the hips first. (health.harvard.edu) Public-health guidance is broader than the coach’s claim: National Health Service guidance for back pain recommends keeping moving and rebuilding strength, even if exercise causes mild symptoms at first. Its examples include knee rolls, pelvic tilts, knee hugs and cat-camel movements. (nhsinform.scot) That matters because “low-back pain” is a catch-all label, not a single diagnosis. Cleveland Clinic says pain near the front of the hip can also come from hip-flexor strain, pinched nerves, herniated disks or femoroacetabular impingement, which is also called hip impingement. (my.clevelandclinic.org) Cleveland Clinic says hip-flexor strains are common in athletes, but can also affect people who suddenly push harder than usual. The same page advises seeing a provider for sudden sharp pain, severe symptoms or pain that lasts for weeks. (my.clevelandclinic.org) The practical takeaway is narrower than the headline: if sitting leaves your hips stiff and your back tense, hip mobility work is one reasonable place to start. If the pain is severe, shoots down the leg, or does not improve, the next step is medical assessment, not more stretching. (health.harvard.edu, my.clevelandclinic.org, nhsinform.scot)
