Back pain is one of the most common reasons people end up in a spine surgeon’s office. Most of it is preventable. Some of the most instructive patients I see are in their late 80s — with imaging that would make a radiologist wince — who are virtually pain-free because they have never stopped moving.
From the clinic — a pattern worth understanding
“I see patients in their late 80s with MRIs and X-rays that look objectively terrible. Severe stenosis. Disc collapse. Arthritis at every level. And they come in walking briskly, asking about getting back to pickleball.”
These patients have something in common: they never stopped moving. Their spines have degenerated the way all spines degenerate over eight decades — but their muscles, their core, their overall conditioning have compensated for what the imaging shows. The spine is supported, stabilized, and loaded through a system that has been maintained. Compare them to a patient of the same age who has been sedentary for twenty years — the imaging may look similar, but the functional picture is completely different.
The lesson is not subtle. A body in motion stays in motion. The spine is not special in this regard. It responds to load, to movement, to conditioning. The patients who age best are almost always the ones who kept moving — not the ones who were most careful.
This is not to say activity prevents all back pain or that degeneration is irrelevant. It is to say that the most powerful thing most people can do for their spine is the most obvious: stay active, strengthen the right muscles, and move correctly. The tips below are practical, evidence-informed, and grounded in what actually makes a difference over the long run.
01
Daily mechanicsPosture — what it actually means
Good posture is not about sitting up ramrod straight at all times. It is about maintaining the spine’s natural curves — lumbar lordosis, thoracic kyphosis, cervical lordosis — in whatever position you are in, rather than collapsing those curves under load or fatigue. The spine is strongest and least stressed when its natural alignment is preserved.
Posture tips — sitting, standing, sleeping
🪑Sitting
Lumbar support preserving the inward curve of the lower back
Feet flat on floor, knees at or slightly below hip height
Shoulders relaxed, not rounded forward
Screen at eye level — chin neutral, not poked forward
Stand and walk briefly every 30–45 minutes — prolonged sitting loads lumbar discs more than standing
🧍Standing
Feet hip-width apart, weight evenly distributed
Do not lock the knees — a slight soft bend maintains alignment
Hips level with shoulders — avoid a pronounced anterior pelvic tilt
For prolonged standing, one foot on a low stool reduces lumbar load
Back or side sleeping preferred — stomach sleeping flattens lumbar lordosis and rotates the cervical spine
Side sleeping: pillow between knees keeps pelvis level and reduces lumbar rotation
Pillow height should keep the cervical spine neutral — not flexed or extended
Mattress firm enough to support the spine without sagging
02
Spine-strengtheningCore exercises — the muscles that protect the disc
The core is not the six-pack. It is the entire cylinder of muscle that surrounds the lumbar spine — the abdominals anteriorly, the paraspinals and multifidus posteriorly, the diaphragm superiorly, and the pelvic floor inferiorly. When these muscles are strong and coordinated, they act as an internal brace that reduces compressive and shear forces on the discs during every movement. A weak, uncoordinated core shifts that load directly onto the passive structures of the spine — the discs, the facets, the ligaments.
Six spine-protective exercises worth doing regularly
PlankIsometric core hold — trains the entire anterior and lateral core under load without spinal flexion. Start at 20–30 seconds and progress. Forearm or extended arm variations.
BridgeSupine hip extension strengthens the glutes and lumbar extensors. Lie on back, knees bent, feet flat. Lift hips to form a straight line. Hold, lower, repeat. Single-leg variation for progression.
Bird DogContralateral arm-leg extension from quadruped position. Trains anti-rotation stability and multifidus activation — the deep lumbar stabilizer most affected by disc disease and chronic pain.
Cat-CowGentle segmental spinal mobility through flexion and extension. Warms up the spine, promotes nutrition of the discs through fluid movement, and develops proprioceptive awareness of spinal position.
Dead BugSupine core stabilization — opposite arm and leg extend toward the floor while maintaining a neutral lumbar spine. More challenging than the bird dog for anterior core activation.
Wall SitIsometric quad and hip strengthening in a position that loads the spine safely. Strong legs contribute directly to reduced lumbar loading during daily activity and lifting.
03
MechanicsProper lifting — the spine’s highest-risk moment
Improper lifting is one of the most common precipitants of acute disc herniation and lumbar muscle injury. The mechanics are simple and become automatic with practice — the problem is that most people use the wrong pattern for years before the disc gives out. The back is not designed to be the primary mover when lifting from the floor. The legs are.
Lifting mechanics — do this, not that
Do
Bend at the hips and knees — not the waist. The hinge is at the hip, not the lumbar spine.
Keep the object close to your body throughout the lift. Distance from the body multiplies lumbar load exponentially.
Engage the core before initiating the lift. Brace as if you are about to take a punch — this activates the internal brace before load reaches the disc.
Drive through the legs to stand. The quadriceps and glutes do the work; the back maintains position.
Turn your whole body to change direction. Pivot with your feet, not your trunk.
Avoid
Bending at the waist with straight legs — the classic back injury mechanism. Maximum lumbar flexion under load.
Holding the object away from your body. Every inch of distance from the spine multiplies the compressive force on L4-L5 and L5-S1.
Twisting while loaded — the combination of flexion, compression, and rotation is the highest-risk mechanism for disc herniation.
Lifting objects that are too heavy without help. Asking for assistance or using a mechanical aid is not weakness.
Lifting in a hurry — most back injuries happen on the tenth or fifteenth lift of the day, when fatigue reduces form and attention.
04
The most important oneStay active — a body in motion stays in motion
If there is one principle that outweighs everything else on this list, it is this: keep moving. Not any particular exercise protocol, not any specific stretching routine — just the sustained commitment to regular physical activity throughout life.
The patients who demonstrate this most vividly are not the young athletes. They are the patients in their late 80s I mentioned at the top — the ones whose MRIs could be used as a textbook example of advanced degeneration and who still walk into my office without a limp. What they have in common is decades of staying active. They never used age or a back pain episode as a reason to stop. The spine, like the heart and the lungs, responds to the demands placed on it. Remove the demand and the supporting system atrophies. Maintain the demand and the system maintains.
Staying active — what counts and why it works
🚶
Walking — the most underrated spine exerciseWalking loads the spine rhythmically, activates the paraspinal and core musculature, promotes disc nutrition through fluid movement, and maintains the aerobic conditioning that underlies general tissue health. Thirty minutes most days is sufficient. Incline walking increases intensity without the impact of running. This is the exercise most compatible with any age, any fitness level, and any history of back pain.
🤸
Stretching — hamstrings, hip flexors, thoracic spineTight hamstrings pull the pelvis into posterior tilt, flattening the lumbar lordosis under load. Tight hip flexors from prolonged sitting pull the pelvis into anterior tilt, increasing lumbar extension stress. Both are common and both are correctable with consistent stretching. Hamstring stretches, kneeling hip flexor stretch, and thoracic rotation (seated spinal twist) address the most clinically relevant tightness patterns. Child’s pose for lumbar flexion relief.
🏊
Low-impact aerobic activity — swimming, cycling, ellipticalFor patients with active back pain or disc disease, these modalities allow aerobic conditioning without the impact loading of running. Swimming in particular provides aquatic traction and full-body activation with near-zero spinal compression. Cycling is excellent for cardiovascular fitness but can provoke lumbar pain in a flexed position — an upright or recumbent bike is better tolerated by most back pain patients.
⚖️
Maintain a healthy body weightEvery pound of excess weight carried at the abdomen shifts the center of gravity forward, increasing lumbar extension stress and disc loading at L4-L5 and L5-S1 with every step. This is not a cosmetic observation — it is a direct mechanical relationship. Reducing abdominal load reduces lumbar load. Calcium and vitamin D support bone mineral density, which matters for the vertebral endplates that transfer force between disc and bone.
💧
Stay hydrated — the discs depend on itIntervertebral discs are avascular — they receive nutrition and hydration by diffusion through the endplates during loading and unloading cycles with movement. Dehydration reduces disc height and impairs this nutrient exchange. Adequate hydration supports disc health at the most basic biological level. This is not a dramatic intervention, but it is real.
05
Your work environmentErgonomics & breaks — sitting is a spine-loading activity
Intradiscal pressure studies have consistently shown that sitting — particularly in a slumped, flexed posture — generates higher lumbar disc pressure than standing upright. Most desk workers spend 6 to 8 hours per day in this position. The cumulative effect over years is significant. The interventions are straightforward.
Desk work and ergonomics — what actually helps
⏱
Stand and move every 30–45 minutesA brief 2–3 minute walk every half hour is not a significant interruption to productivity. It is a meaningful reduction in cumulative lumbar disc load over the course of a workday. Set a timer if necessary. The goal is to break the static seated position before disc pressure and paraspinal fatigue accumulate.
🖥
Screen at eye level — neutral cervical spineFor every inch the head moves forward of its neutral position, the effective weight on the cervical spine increases substantially. A monitor that is below eye level or a phone held in the lap produces a sustained cervical flexion load for hours per day. Screen height at or slightly below direct eye level keeps the head in neutral and reduces cervical disc and facet loading.
🪑
Ergonomic chair with lumbar support — or a small cushionThe chair does not need to be expensive. It needs to support the lumbar lordosis rather than allow it to collapse in a slumped posture. A small rolled towel or lumbar cushion placed at the small of the back achieves this in any chair. Knees at or slightly below hip height. Feet flat on the floor or a footrest.
👟
Supportive footwear — the foundation of postureHeel height alters pelvic tilt and lumbar curve. High heels shift the pelvis anteriorly, increasing lumbar extension stress and lumbosacral angle. For patients who spend long periods on their feet, proper arch support reduces fatigue-driven compensation patterns that eventually affect the lumbar spine. This is not about fashion — it is about the kinematic chain from foot to spine.
“The best spine treatment I know is one I can’t prescribe: a lifetime of staying active. The patients who demonstrate this most clearly are the ones who walk in at 87 with imaging that would frighten most radiologists — and ask me when they can get back to the golf course.”
None of this is complicated. Good posture, a strong core, correct lifting mechanics, and consistent physical activity are the most powerful spine-protective interventions available — more powerful, in most cases, than any surgical technique. They are also entirely within your control starting today.
If you have back pain that is not responding to these measures, or if you have neurological symptoms — weakness, numbness, bladder or bowel changes — that warrants evaluation. But for most people reading this, the prescription is simpler: keep moving.
Back pain that isn’t getting better deserves a real evaluation.
Most back pain resolves with the right conservative care. When it doesn’t — or when there are neurological symptoms — that is the right time to talk. Telemedicine available from anywhere in Florida.
