What to Know About Biking and Lower Back Pain

Lower back pain from cycling could be due to bike posture, muscle imbalances, or biking too much. Conservative treatments might be enough to manage existing pain, but bike adjustments and core exercises could help prevent it.

Biking is a great way for people of all fitness levels to stay in shape. It can help you strengthen the muscles in your legs and improve your cardiovascular fitness. It also has a relatively low risk of injury compared with many other forms of exercise.

Lower back pain is the most frequent overuse injury affecting cyclists. In a 2021 survey of 1,274 amateur Italian cyclists, researchers reported that 55.1% of athletes experienced lower back pain in the past year.

A combination of factors can contribute to the development of back pain, including an improper-fitting bicycle and too many weekly miles.

Almost two-thirds of that $3.3 trillion cost – 64% – is paid for by American tax dollars, and that amount is growing.

Lower back pain is a common complaint among cyclists. Muscle weakness, poor bike positioning, and muscle imbalances may all play a role.

Here are some of the factors that might contribute to back pain when biking.

Spinal flexion

Spinal flexion is when your spine is bent too far forward. Sustained and repeated spinal flexion is linked to lower back pain in cyclists.

A handlebar position that’s too low may put you into excessive spinal flexion that contributes to back pain.

Muscle imbalances and weakness

In a 2017 research review , researchers found evidence that muscle imbalances in the core and spinal muscles are risk factors for lower back pain in cyclists.

In the same study, researchers also found a link between back pain in cyclists and decreased thickness in the transverse abdominis muscle and muscles in the back around the spine. Your transverse abdominis is the deepest layer of muscle in your belly.

Too many weekly miles

Your chances of developing back pain seem to increase as your number of weekly miles increases. It’s generally a good idea to slowly increase your weekly miles over time as opposed to suddenly increasing your training volume.

Fatigue from high training volume can alter your position while cycling and make you more prone to injury. In a 2021 study , researchers linked fatigue to several changes that could predispose you to injury, such as:

greater spinal flexion
greater pelvic and mid-back tilt
greater hip adduction, bringing your thighs closer together

Whole-body vibration

Cycling can expose your body to whole-body vibration, especially if your bike is on uneven surfaces. These vibrations may increase your risk of lower back pain and injury.

There’s limited research available on how much vibration cyclists are exposed to. In a 2021 study , researchers found that two types of seats designed to reduce vibrations were inefficient at doing so.

Is it OK to ride a bike with lower pain?

It can be difficult to know when it’s safe to exercise when you’re feeling pain. Some soreness after working out is typical, but pain can also be a sign that you need to take a break.

You might want to avoid riding your bike if you answer “yes” to any of the following questions:

Does my back feel worse after exercising?
Is my pain sharp and severe?
Am I changing the way I’m cycling to avoid pain?
Is my pain getting worse over time?
Do I feel any numbness, tingling, or other potential signs of a neurological problem?
