Taller people are at increased risk of injury. On this page, I explain why this is the case, focusing in on back injuries in particular. I also discuss some exercises, activities, spine sparing strategies, and ergonomics adaptations that can help in the prevention and recovery from back injuries.

Much of this section of Tall Life draws on the work of the world renowned spine researcher, Stuart McGill, whom I had the good fortune of meeting while I was struggling with back pain of my own. If you want to learn from the expert himself, I suggest starting with his latest book, Back Mechanic.1

Why Tall People Have a Higher Risk of Back Pain and Back Problems

Barbados Joe Walcott, the 5′1″ former world welterweight boxing champion, was well known for entering into matches against significantly larger opponents. His rather famous reasoning was that, “The bigger they are, the harder they fall,” and he figured a smaller fighter could take advantage of this. For anyone other than Barbados Joe Walcott, this would probably be a bad bet. But, he was right that a larger person experiences more force when they hit the ground.

But shouldn’t our taller bodies be better suited to larger forces? They are, but not proportionally so. This is because the taller body, despite being absolutely stronger, is relatively weaker, as per the Sqaure-Cube Law.

Another issue often pointed out is that our larger bodies have longer levers. To better appreciate this concept, let’s consider the wrench analogy. As we all know, it’s hard to get a nut off a bolt by hand. This is why we have wrenches. And for the tightest nuts, we have extra-long wrenches. This is because a longer wrench can apply more torque (rotational force) to the nut. But while large torque is great for unscrewing a nut, too much can break it. Similarly, taller people’s longer limbs apply more torque to the joints. And as with forces, our larger joints are better at accepting larger torques, but not proportionally so, as per the square-cube law. The result is an increased risk of injury.

Another issue tall people face is that a thicker body experiences more stress when bent or twisted a given angle. You can verify this yourself by bending two different size wooden dowels, noting that the thicker one breaks at a lesser angle.

And yet one more issue is our slower reflexes that result from longer nerves,2–14 as this makes it harder to avoid injurious situations. All of these issues, and perhaps more, increase our risk of injury.

But if size is such an issue, then how is it that larger species get by? Shouldn’t giraffes be constantly suffering from sore necks? The answer is that larger species have had millions of years to adapt for their great size, such as by becoming relatively more big boned. Their legs also tend to be stacked closer to vertical, including when running, and this decreases torques on their joints.5 More generally, they move conservatively and plan far ahead in order to compensate for their slower reflexes.6 Tall people have not benefited from this same extent of evolutionary adaptation for our size, and this, rather than our size alone, is the deeper reason why we’re more likely to become injured.

Many studies confirm that we’re at greater risk for injuries, including to the ankle, knee, hip, back, neck, shoulder, and wrist.7–20 Studies of injury rates in various sports also routinely find tall athletes are at greater risk.8,17–19 And the injuries that afflict the elderly are also more common in tall people, such as hip fractures.20

I’ve injured all but one of the joints I mentioned above. My worst injury by far was to my back. Back injuries can come on suddenly, or gradually as was the case for me. I figure poor posture has a lot to do with it, or more specifically, a deviation from neutral spine posture. This is more likely to occur for tall people both due to ill-fitting manufactured objects and lesser relative strength. But what is it that’s so disastrous about deviating from neutral spine posture in the first place?

A deviation from neutral spine posture corresponds with a bending of the spine. The main problem with a bent spine, Stuart McGill explains, is that uneven pressure is applied to the discs.21 This is particularly problematic for loads that are large (car accident), applied over longer durations (desk work), or applied cyclically (vibrating machinery or sports). Uneven pressure in these instances pushes the gel-like contents of the disc away from center, encouraging a departure from the disc. The simplest way to visualize this is as the squishing of a jelly donut. Sometimes the result is called a herniated disc. I have several discs in my own spine that have been damaged similarly.

Another way discs can become altered is by a loss of water content, which results in a decrease in thickness. This happens naturally over the course of the day as gravity compresses the discs. This is why we tend to be shorter in the evening than in the morning. I actually once bought a car in the evening only to find out the next morning that it was too small for me!

As we age, the discs can lose some of their ability to remain hydrated, and this results in a more permanent reduction in stature. Besides with age though, desiccation can also result from stress, which in theory tall people are more subject too. Once again, many of my discs have been damaged in this way.

As I know from experience, disc damage can cause immense pain. This may come directly from the damaged disc or from the pressure herniations put on sensitive nerves outside the disc. Pain in turn causes tightness, putting more stress on the discs. The resulting injury loop can lead to chronic pain.

Though there’s some evidence that discs can regenerate,22,23 this healing is nowhere near as speedy as for broken bones. One doctor actually told me mine would probably never heal. The fact I wish he’d have told me, though, is that herniated discs and the like are often asymptomatic,24 meaning there are lots of people walking around with them without even knowing it. It would follow then that herniations may become asymptomatic with time. Knowing this early on would have saved me a lot of grief.

To give the discs a chance to become asymptomatic, we must avoid injuring them further. So in this case, prevention and recovery are pretty much the same thing. The key for both is maintaining good posture. This can be aided with exercises, activities, spine sparing strategies, and ergonomic modifications, as explained in the following sections.

Spine Stabilizing Exercises for Tall People Back Pain and Back Problems

When my back first started getting bad, I jumped to the conclusion that this was a sign of weakness. So I hit the gym and started lifting some heavy weights. Similarly, I was told I had to improve my flexibility, so I began working my way up to being able to touch my toes with straight legs, and so on.

As it turns out, I was doing myself more harm than good; I later learned from Stuart McGill that neither high static back strength nor mobility are associated with lower risk of back injury, and can actually have the opposite effect. Instead, it’s good muscle endurance and control that’s important. For further appreciation of this notion, consider that low force tasks extended over long durations, such as standing, or tasks requiring proficient control, such as picking a pencil up off the ground, often lead to injury.

Muscle endurance and control are thus important for maintaining a stable spine, where a given posture, usually the neutral posture, is maintained. This ability can be improved with exercises that challenge endurance and control, such as Stuart McGill’s Big Three Stabilizing Exercises.21 I briefly explain these below. Before attempting these, it’s best to consult a physiotherapist or similar.

Cat-Camel: This first exercise isn’t for increasing stability but rather for increasing the viscosity in the spine, among other benefits, and thus useful for preparing for stabilizing exercises. McGill recommends moving between these two postures approximately five to eight times, integrating movement throughout the entire spine.

#1 Curl-up: With the hands supporting the neutral curvature of the low back and one knee flexed, the head and shoulders are slightly raised from the floor. A possible routine could include three sets with six, four, and then two reps that last ten seconds each, alternating which knee is flexed.

#2 Side Bridge: Support the body weight by the feet and forearm. The less advanced version is done with the knees on the ground. The same rep/set pattern as for the curl-up can be used.

#3 Bird Dog: One arm and one leg, on opposite sides of the body, are raised. The same rep/set pattern as the curl-up can be used.

Posture Correcting Exercises for Tall People Back Pain and Back Problems

A former coach of mine once mentioned to me that I looked strong from in front but weak from behind. What he was noticing was that my chest muscles were overpowering my upper back muscles, causing my shoulders to round forward.

Some years later, I learned that what I was experiencing was part of a fairly common pattern of muscle imbalances known as the crossed syndromes.25,26 They’re called crossed because tight and weak compensations literally cross the body, cascading along its length in an alternating pattern. In the spine, visually, the tight regions are curved inwards while the weak and elongated regions are curved outwards, both contributing to an accentuation of the spine’s natural curvatures.

There are two characteristics of the crossed syndromes that warrant pointing out in the context of tall stature. The first is that the resulting distorted posture relies more on passive support from musculoskeletal tissues, thereby decreasing muscular effort. The second is that they decrease overall stature. Taller peoples’ diminished relative strength and relatively short artificial environment may provide increased incentive for us to adopt the distorted posture, and thereby initiate the syndromes.

Besides the crossed syndromes, there are many other ways posture can become distorted. The good news though is that regularly performed exercises can provide some compensation for the issues leading to postural distortions. The basic idea is to stretch the tight muscles and strengthen the weakened muscles. A physiotherapist or similar can help determine if your posture is distorted and prescribe exercises to correct it.

Activities for Tall People Back Pain and Back Problems

When my back first got bad, I got a lot of suggestions for various activities I could do that might help. Perhaps the most common was to do yoga, for which the benefits for back pain sufferers are well known.27,28

Many yoga poses help build muscle endurance and control and correct common postural distortions. Particularly beneficial are the poses that emphasize neutral spine posture. And beyond the mechanical aspects, there are other reasons why yoga may be helpful for back pain sufferers, including the cultivation of mindfulness.29,30

I’d like to note, though, that Stuart McGill has expressed concern over the yoga poses that twist and bend the spine considerably, such as those below. He explains that this isn’t necessary for building a robust back, and can actually increase the risk of injury. Yet, as McGill demonstrated in a recent yoga workshop I attended, some of these poses can be done more moderately or modified for the individual, which happens to be a central theme in yoga.

I think yoga is particularly great for tall people given it presents an opportunity to improve relative strength, which we tend to lack. The flip side though is that we need to be careful with the poses that require high relative strength. Our other characteristics that warrant caution include lesser flexibility, more numerous injuries, and thicker spine that won’t twist nor bend as readily. Nevertheless, I’ve been practicing yoga with moderation myself for some seven years now and am certain that it has helped me enormously. See the Yoga for Tall People page for more.

The next most common recommendation I got was to take up swimming. This seemed like a great idea to me, particularly because tall people, like 6′4″ Michael Phelps, make great swimmers. As with yoga though, swimming is a varied activity, so different strokes for different folks. The Phelps style butterfly, for example, will probably not be helpful to those suffering from back injuries. Breast stroke and front crawl, on the other hand, may be better. But even these require some extent of twisting and extending of the spine as breaths are taken. The solution I came across is to use a swim snorkel. This negates coming up for air, thereby facilitating a neutral posture along the entire length of the spine. See Swimming Strokes for Bad Backs and Necks for more on this topic.

When swimming is vigorous, it yields cardiovascular benefits, which can be beneficial for back pain sufferers.31 This is likely because of a hypoalgesic effect32; endorphins are released which decrease pain much like morphine does. Extended exercise can also trigger the release of endocannabinoids which can give a euphoric feeling commonly known as runner’s high,33 helping the body to relax. I’ve found cycling to be an even better form of low impact cardiovascular exercise. McGill does point out though that competitive road cycling can encourage too much spine flexion.

Walking, though somewhat less than cycling and swimming, also has cardiovascular benefits. Interestingly, McGill has found a brisk pace—and for tall people this will be particularly fast—better for the back than a stroll. A decent arm swing and looking straight ahead also help. More walking can be interjected into daily life by parking at the far side of the lot, taking the stairs, and my personal favorite, getting a dog.

Food can also have an influence on injury recovery and prevention, including on the body’s inflammation response. Sufficient consumption of Omega-3s in particular has been recognized as important.34

A final concept I’d like to mention is moderation. A routine, whether for an athlete of any level or for an individual recovering from an injury, lies on an inverted U-shaped curve, where the optimum has neither too much rest nor too much training.21 By finding this golden mean, as Aristotle once called it, optimum physique can be achieved.

Spine Sparing Strategies for Tall People Back Pain and Back Problems

Young people, my former self included, tend not to be all that careful with their backs. For instance, I remember my total disregard for spine posture when lifting things, despite my wiser elders advising me to keep a straight back. I did eventually learn, but the hard way, and at great cost to my spine. Perhaps if I��d read it in a book such as this, it might have played out differently. Below are a variety of spine sparing strategies.

Maintain a neutral spine posture: Neutral spine posture is particularly important when under load, especially prolonged static and cyclical loads.

Use the lower extremities for getting low: The squat, hip hinge, lunge, and golfer’s lift are all robust postures for getting low.

Minimize torque arms: By lifting close to the body and pushing and pulling through the center of the spine, torque acting on the spine is minimized. When pulling low door handles, for example, torque can be reduced via a slight lunge.

Contract core muscles before lifting heavy loads: Though this increases the load on the spine, it ensures the neutral posture is maintained, which tends to be more critical.

Use aids: Use lifting tools such as hoists, dollies, and furniture straps. Protective clothing can also help as it encourages holding the load closer to the body, thereby reducing torques. Knee pads are particularly helpful for us as they encourage getting low via kneeling rather than flexing the spine.

Use mechanical advantage: When lifting a log, for example, use leverage by lifting one side at a time. Better yet, have a second person lift the other side as is common in such tasks as moving a couch.

Avoid prolonged static postures: Even low stresses, when maintained for long periods such as for desk work, can lead to injury. So it’s best to regularly get up and move.

Avoid bending and lifting early in the morning and after sitting: The discs are most hydrated after waking, and this leads to a stiff spine. Sitting tends to have the opposite effect, but only on one side of the spine. It’s best to delay bending and strenuous activity after both waking and sitting.

Ergonomics for Tall People Back Pain

Another factor that needs addressing is the poor ergonomics that result from ill-fitting objects. This is such an enormous problem for tall people that I have devoted an entire section of this website to it: Ergonomics. Some featured articles are below. For me, addressing my ergonomics in the kitchen, in my car, and at my desk had the greatest benefit for my back pain and back problems.
