New Delhi: Back pain is often blamed on a bad mattress, long work hours, ageing, travel, or lifting something heavy the wrong way. While all of these can contribute, one of the most overlooked reasons behind recurring back pain is surprisingly simple: weak core muscles.
A lot of people hear the word “core” and immediately think about six-pack abs or gym workouts. In reality, the core has very little to do with appearance. It refers to the deeper group of muscles around the abdomen, lower back, pelvis, and hips that help stabilise the spine during everyday movement. When these muscles are not functioning well, the back ends up absorbing far more strain than it is designed to handle.
When Everyday Movements Start Hurting
“A pattern that’s becoming very common now is people dealing with regular lower back pain, even though their daily routine isn’t physically strenuous. Hours spent sitting – whether at office desks, in cars, or hunched over laptops on sofas and beds – slowly start affecting how the body holds itself. Gradually, posture changes, supporting muscles lose strength, and the lower back ends up carrying more strain than it should,” explained Dr Paruchuri.
What surprises many people is how little movement it sometimes takes to trigger pain once the supporting muscles become deconditioned. A slight bend while picking up a bag, standing for too long in the kitchen, carrying groceries, or even getting up awkwardly after sitting for hours can suddenly lead to spasms or stiffness.
Why the Core Matters More Than People Think
“The spine depends heavily on surrounding muscles for support. When the core remains weak, smaller muscles in the lower back start compensating continuously. Those muscles fatigue much faster, which is one reason people often describe a dull ache that worsens as the day progresses,” explained Dr Paruchuri.
Some also notice:
- stiffness after sitting
- discomfort while standing for long periods
- pain during sudden movements
- difficulty maintaining posture
- tightness around the hips or lower back
“Interestingly, not everyone with weak core muscles looks unfit. Someone may appear slim or physically active and still have poor muscular support around the spine. Walking alone, while excellent for overall health, does not always strengthen the deeper stabilising muscles adequately,” added Dr Paruchuri.
Another issue is that many adults stop using these muscles effectively without realising it. Long sedentary routines gradually reduce muscular engagement. The body begins relying on passive structures like joints, ligaments, and spinal discs instead.
How Sedentary Habits Affect Back Health
The way many people work today has quietly changed how their bodies cope physically. Sitting for most of the day, moving very little between tasks, working in awkward positions, and not doing enough strengthening activity can gradually start affecting the back much earlier in life than people expect.
“Younger adults are increasingly reporting chronic back discomfort that was once more common in older age groups. In many cases, scans may show only minor structural changes despite significant pain. That mismatch can be confusing, but muscle weakness and poor movement patterns often play a major role,” said Dr Paruchuri.
Stress also affects the body more physically than people realise. Many individuals unconsciously tighten muscles around the neck, shoulders, abdomen, and lower back during periods of anxiety or mental fatigue. Over time, this constant muscular tension adds further strain.
Why Rest Alone Usually Doesn’t Solve It
“One misconception around back pain is that complete rest will fix it. Taking it easy for a day or two can sometimes settle severe pain, but staying inactive for too long usually makes the muscles lose even more strength, which often slows down recovery instead of helping it,” warned Dr Paruchuri.
Gradual strengthening, posture correction, mobility work, and consistent movement usually make a far greater difference over time than temporary pain relief alone.
Simple Habits Matter
- avoiding prolonged sitting without breaks
- improving posture
- strengthening abdominal and pelvic muscles
- maintaining flexibility
- staying physically active consistently rather than occasionally
- Bottomline
The goal is not building an athletic body. It is giving the spine enough muscular support to tolerate everyday life without constantly becoming overloaded.
Dr Paruchuri concluded, “Back pain rarely develops because of one single event. More often, it builds quietly through months or years of weak support, prolonged sitting, poor movement habits, and reduced conditioning. By the time pain appears regularly, the body has often been compensating for quite some time already.”
