Introduction

More than half of cyclists report having low back pain, which should be reason enough for you to read through this article. Either you are one of these individuals, or in all likelihood will be at some point in your cycling career. Unfortunately, there are various things about our sport that almost guarantee an achy back with enough time and patience. 

If we are the ones to break this news to you, we apologize. But just the singular act of sitting on a bike can actually have serious detrimental implications for your lower back.

Today we will give you the information and guidance to eliminate cycling low back pain once and for all. A note before we dive in, ensure you have done (or have had a professional perform) a proper bike fit. Without this, all the following advice could be a non-starter. If that’s in order, then we hope you find this helpful. Here is a comprehensive guide to some of the most common issues relating to lower back pain in cyclists, and most importantly, how to address them.

Compression (Problems)

A famous study from 1970 showed that while standing you have (on average) about 100 kg of pressure on your lumbar discs. If you sit down, this pressure increases to 140 kg. If you bend forward while sitting, this pressure increases to 185 kg. 

Remind you of anything?

Constant compression of your spinal discs not only puts you at risk for disc herniation, it is often the cause of weakness, numbness, tingling and pain that can radiate out from the back and into your limbs through conditions like sciatica. This might help explain why some people experience back pain after cycling, resulting from the increased compressive forces sustained during the ride.

Many people think back pain originates from things like hard physical labour, but the evidence says otherwise. There is a far higher percentage of people with back pain in rich, developed countries where people are more sedentary. The same phenomenon is seen when comparing people in urban centers to others in rural communities. A lot of this comes down to sitting. 

There is a devilish trick at play here, because people think getting on their bike is going to make them stronger, more resilient and LESS susceptible to common problems like low back pain. As we’re starting to see, this is not exactly true. So we need to find ways to counteract the compression we experience on our bikes, and in so many other areas of our lives.

Compression (Fixes)

You may have heard the interesting fact that you’re taller in the morning than you are at night. This is a result of gravity acting down on you throughout the day. As we age, the repetitiveness of this effect on our spinal columns (among other things) can actually cause our spinal discs to lose fluid, dry out, become brittle, painful and injured. 

There are however ways to give our spines the love they need, and preserve their integrity throughout our lives. That is by actively taking them through full ranges of motion, and doing exercises to neutralize the excessive compression forces we subject them to. Here are two things to help that you’re probably not currently doing:

Hanging

Our ancestors have been doing it for hundreds of thousands of years, children do it on the playground, but for some reason as adults we don’t do it at all. You don’t need an inversion table, fancy boots or medieval torture devices to decompress your spine…all you need to do is hold onto a bar – and relax.

Hanging has a number of incredible benefits. It expresses full shoulder flexion, increases grip strength and decompresses your spine to name a few. A door frame pull up bar is inexpensive and easy to use. Try doing intermittent sets throughout the day to help loosen things up, especially after rides. 

If you’re not strong enough to hold yourself, or can only hold for a few seconds, use your feet on a platform or the floor to take some of the weight off.  It’s important to give yourself time to gradually get stronger in this position. Our modern lifestyles and the sport of cycling rarely take our arms overhead. So take your time, start slow and don’t rush.

Full Squats (Resting)

Remember those lower income countries we mentioned? Their citizens often do something far better than sitting when eating meals, waiting for the bus or even just talking to friends. It’s the same thing every child does when they want to pick something up off the ground. Most of us know it as an exercise, but it’s actually fundamentally a resting position. The squat.

Sitting in a full squat is a natural position for our bodies; it helps us digest food, keeps our hips, knees and ankles mobile, and actually places our colons in the best position to poop (pooping in the woods, anyone?) It also has a gentle stretching and decompressive effect on our lower backs, with the force going through our feet and the ground instead of our backsides and a saddle.

This might be hard if you’re inexperienced, but you can use your desk or any other sturdy implement to hold onto while in this position. Placing a book under each heel can help as well. Try spending short periods of time down there, and you’ll be shocked at how mobile, supple and energetic you start to become. After the initial period of incredible discomfort, of course!

Core (Problems)

The core is grossly misunderstood, especially when it comes to cycling and lower back pain. Lower back pain is strongly associated with a muscle called the Transversus Abdominis (TVA), your deepest abdominal muscle. It wraps around your organs and entire midsection like a corset, and is your body’s equivalent to the weight belts you see people wearing in gyms.

As you can see from this photo, the TVA shares an intimate relationship with your diaphragm, multifidus and pelvic floor muscles. All of them work together in a loop to create trunk and low back stability. One of the most notable differentiators between cyclists with back pain is that they have less TVA thickness than riders without low back pain.

When you activate your TVA, your belly button draws in towards your spine. This pushes your organs up against your diaphragm and down against your pelvic floor, creating a compressed cylinder around your low back. Because the tendons of your diaphragm reach down towards the L2/L3 vertebrae, the upwards pressure of this action actually lifts those vertebrae slightly, decompressing L4/L5 and L5/S1 below. 

L4/L5 and L5/S1 just so happen to be the two most common sites for disc herniations, and TVA weakness will almost undoubtedly be found in individuals with those injuries. 

Starting to see the importance of proper core function?

Core (Fixes)

Having a stronger, more supported core should start with learning how to use your TVA (as opposed to hammering your abdominals with excessive exercise, which is so often the advice given). This will increase the tone of your midsection and support your organs, while also adding support to the lower back even in the compromised position your bike puts you in. 

So, how do you do it?

Think about putting on a tight pair of pants, you know how you suck your belly button in to do so? That’s the action of your TVA. To practice, try taking in a deep breath of air. Now slowly exhale, and at the same time draw your belly button in towards your spine. The TVA assists in expiration, so timing these two actions together can help increase awareness of the muscle.

Every time you bend over, pick something up, push/pull something or MOVE at all – you should be activating your TVA first. Take a breath, draw the belly in and hold. Complete the movement, then repeat. Remember, if your TVA is engaged, your back is supported. With enough practice, your nervous system will learn to automatically activate it every time you move.

“Does this mean you should hold your tummy in all day and the whole time you’re cycling?”

Of course not! But by strengthening this muscle through regular use you will increase its resting tone. So even when not actively engaging it (like when you’re riding) it will be tight, strong and supportive. 

Poor resting abdominal tone versus good resting abdominal tone. Neither of these people are overweight, but the man’s belly is protruding because his organs are falling forward against a weak abdominal wall.

Hips (Problems)

We now get to one of the most problematic areas in the body when it comes to low back pain and cycling, the hips. More specifically, the hip flexors. Even more specifically, the psoas muscle. The psoas is your primary hip flexor, and is indeed the only muscle connecting your upper and lower body. 

It attaches to your femur and all five lumbar vertebrae, so it has significant influence on your lower back. While cycling, your hips are always in some state of flexion, never reaching full extension. The hip flexors actually help pull your leg up through the recovery phase in preparation for propulsion in the power phase, as well. All this flexion can lead to tightness.

Tight psoas muscles will pull on the lumbar vertebrae. This tips the pelvis forward by creating an excessive curve in the low back (lordosis), causing the vertebrae to pinch together, compressing nerves and often resulting in pain. Tight hips also inhibit the function of their antagonists, the glutes, which are tremendously important for overall strength and balance in the body.

Hips (Fixes)

Static stretching in general can be a great way to improve flexibility. Doing it before riding however, is not necessarily recommended. When you hold stretches for extended periods of time, it has a relaxation effect on the muscles by decreasing their neural excitation, meaning they won’t be able to contract as hard as usual, leading to decreased cycling performance.

We can intelligently use this effect to our benefit, though. If we want to decrease the activity of a hyperactive muscle, such as our hip flexors, then doing a passive stretch on them before, and even intermittently during, our rides can be a handy tool for relieving back pain while cycling. 

Give this stretch a try before your next session:

Lunge Stretch

Get into a wide standing lunge position, try not to arch your lower back (tuck your tail), and then lean into your front knee, opening up the hip on your extended side. You should feel a stretch in the front of that back hip. Hold for 30-60 seconds. Repeat on the other side. If this is too tiring, you can lower the back knee to the ground for support. 

This will have a “deadening” effect on your hip flexors and possibly provide some relief to the low back while riding. If you get some initial relief, and then feel your lower back pulling after some time riding, simply stop and perform this stretch again to see if it makes a difference. If it does, then you can start doing this stretch on rest days for a more permanent effect.

Back Strength (Problems)

Cycling basically does nothing in the way of strengthening your back, but paradoxically, you need a strong back to be a good cyclist. Being bent over on the bike forces our back muscles to work extremely hard to maintain some sort of rigidity and stability during that time, but if we lack the endurance to do so, the body resorts to other mechanisms.

There is something that takes place in your body called the flexion-relaxation phenomenon. When you sub-maximally flex your spine, your body will relax the muscles of the back to rely passively on deeper structures like tendons and ligaments for energy conservation. Increasing the strength and endurance of our back musculature can help mitigate the effects of the prolonged wear and tear this could have on our spines while cycling.

One revealing way to tell if a back is weak is just by looking at it. If you can see the spinous processes on somebody’s back (bumps along the spine) while standing, that is a screaming sign of an area that is at risk for injury. Having a strong back is not just beneficial in cycling but for every other part of life.

Back Strength (Fixes)

Training the low back and back in general to handle heavy loads over sustained periods of time will dramatically reduce your risk of pain and injury while on the bike. Adding extra tissue to the area will create a strong, supportive environment that can do the activities you’re asking it to.

Any exercise where you’re picking something up off the floor, like a deadlift, is going to be the best bang for your buck. This is because your low back is going to be the pivot point for the load you’re trying to pull. Performing high repetitions with moderate weights is going to train your muscles to be strong over time (endurance), which is exactly what you want as a cyclist.

Interestingly, many cyclists complain of lower back spasms while riding. This is because the muscles are being overstretched, so they forcefully contract to try to bring you out of that position (i.e. your body is smarter than you!) If you want to avoid spasms, make your back stronger!
