Old injury? Aching joints? Here is why movement
is usually the answer, not the problem.

Most chronic pain is not where you think it is

This sounds counterintuitive, but it holds up well under scrutiny. Whether the pain is in the lower back, the knees, the hips, or the shoulders, the root cause is very often the same. The muscles surrounding that joint or region are weak or underused, which means the joint itself is absorbing load it was never designed to handle alone. The joint protests. You feel pain. And the natural instinct is to rest and protect the area, which makes the weakness worse.

The lower back is surrounded by glutes, deep core, and hip flexors that are supposed to carry the load. Knees are stabilised by the quadriceps and hamstrings above and the ankle below. Hips depend on glute strength and hip mobility. Shoulders rely on the rotator cuff and the muscles of the upper back. When any of these supporting muscles are weak or switched off, the joint in question compensates, and that compensation eventually becomes painful.

Scan images of adults with lower back pain and adults without lower back pain show surprisingly similar findings. Disc bulges, degenerative changes, and other structural variations are common in people with no pain at all, and their absence does not guarantee a pain-free back. The relationship between what shows up on a scan and what someone actually experiences in their daily life is weaker than most people assume.

What is more predictive of chronic pain in most regions is weakness in the supporting musculature. A sedentary lifestyle, desk work, long periods of sitting, and inactivity switch off the muscles that joints depend on for support and stability. The result is a joint doing too much work and signalling its distress through pain. This pattern appears whether it is the lower back, the knees, or the hips.

Why rest makes it worse

When something hurts, the instinct is to stop moving it. For an acute injury, some rest is appropriate. But chronic lower back pain, the kind that has been present for weeks or months, responds poorly to extended rest. Muscles that are already underactive become more so. Joints stiffen. The nervous system becomes more sensitised to pain signals. What started as a muscular problem becomes reinforced by weeks of inactivity.

The clinical guidance on lower back pain has shifted significantly in recent decades. Extended bed rest is no longer recommended for most presentations of lower back pain. Movement, specifically the right kind of movement, is consistently shown to produce better outcomes than rest alone.

What the right exercise looks like

Starting with gentle movement rather than aggressive loading is the right approach. Walking is often the first and most accessible intervention. It mobilises the spine, activates the muscles around the lower back, and encourages blood flow to the area without loading it heavily.

From there, the focus should be on building strength in the muscles that support the lower back. The glutes are the most important. A significant proportion of lower back pain cases show marked weakness in the glutes, the large muscles of the buttocks that are responsible for hip extension, stabilisation during single-leg movements, and protection of the lower back during everyday activities like bending, lifting, and climbing stairs.

Core strength is the other key area, but core in the broader sense: the deep abdominal muscles, the muscles along the spine, and the hip flexors, not just the superficial muscles that crunches target. Building genuine functional core strength involves exercises like deadbugs, bird-dogs, and planks rather than the kind of exercises that involve aggressively flexing and extending the spine.

Hip mobility also plays a significant role. Tight hip flexors, common in people who sit for long periods, pull on the lumbar spine and create an anterior pelvic tilt that adds stress to the lower back. Regular mobility work targeting the hip flexors and piriformis can make a meaningful difference to lower back symptoms.

When to see a professional

Exercise is appropriate for the vast majority of lower back pain presentations in otherwise healthy adults. There are, however, some situations that warrant medical assessment before starting an exercise programme. Pain that radiates down one or both legs, particularly below the knee. Numbness or tingling in the legs or feet. Loss of bladder or bowel control. Pain following a significant impact or fall. Unexplained weight loss alongside back pain. These presentations should be assessed by a GP or physiotherapist before beginning exercise.

For the majority of people with chronic lower back pain that does not include these features, the evidence strongly favours structured, progressive exercise as the primary intervention.

Training with injuries and pain at Motus

All Motus sessions are coached and adapted. If you come in with a back, knee, hip, or shoulder that has been giving you trouble, that is not a reason to avoid starting. It is something that gets factored into how your sessions are designed from day one. Movements are selected and modified based on what your body can currently handle. Load is built progressively. The focus is on building strength in the places that have been letting the painful area compensate for too long.

Several people in the Motus community started training specifically because of chronic pain, old injuries, or movement problems that had been limiting them for years. Consistent, well-coached strength training has made more difference than years of physio alone for many of them. Not because exercise is a magic fix, but because building genuine strength in the right places addresses the root cause rather than managing the symptom.
