IS CYCLING BAD FOR YOUR BACK?

By Anthony WalshRoadman CyclingUpdated 10 July 2026

ANSWER

Cycling is not inherently bad for your back, but the sustained forward-flexed position can cause lower back pain if the bike is set up incorrectly, your core is weak, or your hamstrings are tight. The most common causes are excessive reach (bars too far away or too low), a saddle that is too high (forcing pelvic tilt), and insufficient core strength to stabilise the pelvis during pedalling. Research shows that 60-70% of recreational cyclists experience some lower back discomfort, but the vast majority of cases are resolved through bike fit adjustments, core conditioning, and flexibility work — not by stopping cycling.

KEY TAKEAWAYS

60-70% of cyclists experience lower back pain, but it is usually fixable with bike fit and core work.
Excessive reach or a too-aggressive position is the most common bike-fit cause.
Weak core muscles allow the pelvis to rock, loading the lower back excessively.
Tight hamstrings pull the pelvis into posterior tilt, increasing lumbar flexion.
A more upright position (higher bars, shorter stem) immediately reduces back strain.

WHO THIS IS FOR

IS THIS YOU?

The rider with lower back pain during or after rides

Your back aches during long rides or is stiff and sore the next morning.

The rider considering cycling but worried about back problems

You have a history of back issues and want to know if cycling will make them worse.

THE ROADMAN VIEW

Most cycling back pain is a fit problem, not a cycling problem. You are sitting in the same position for hours, often with your arms stretched out and your back rounded. If the reach to the bars is too long or the bars are too low, your lower back is doing the work of holding you up instead of your core. Add a weak core and tight hamstrings and it is only a matter of time before something starts to ache.

The fix is usually simple: raise the bars (add spacers or swap to a shorter stem), check that your saddle is not too high, and start doing core work twice a week. Planks, side planks, and bird-dogs for 15 minutes. Within a month, most riders see a significant reduction in back pain. If it persists, see a physiotherapist who understands cycling biomechanics.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Phil BurtFormer head of physiotherapy, British Cycling
The forward-flexed cycling position is not harmful in itself — the spine is designed to flex. Problems arise when the degree of flexion exceeds the rider's flexibility or when the position is maintained for hours without adequate muscular support. Bike fit adjustments that reduce reach or raise the handlebar typically resolve 80% of cycling-related lower back pain.
Dr Stuart McGillSpine biomechanist, University of Waterloo
Spinal flexion combined with repetitive loading — as in cycling — is a risk factor for disc irritation. The protective strategy is a stable core that maintains lumbar neutral position under load. Core endurance (the ability to maintain activation for prolonged periods) matters more than core strength for cyclists.

PRACTICAL APPLICATION

DO THIS WEEK

Raise your handlebar position
Add 10-20mm of spacers under the stem or swap to a shorter stem (10-20mm shorter). This reduces reach and increases your torso angle, taking load off the lower back. You may lose a small amount of aerodynamic efficiency, but the reduction in pain is worth it.
Start a core endurance routine
Three exercises, twice per week: front plank (3 x 30 seconds, building to 60), side plank (3 x 20 seconds each side), and bird-dogs (3 x 10 per side). These build the endurance to hold your pelvis stable during long rides.
Stretch your hamstrings daily
Tight hamstrings pull the pelvis into posterior tilt, which flattens the lumbar spine and increases disc pressure. 2-3 minutes of hamstring stretching per leg each day (standing or lying) improves pelvic position on the bike.
Change position during long rides
Move your hands between the hoods, drops, and tops every 15-20 minutes. Stand out of the saddle for 20-30 seconds every 15 minutes. These micro-changes redistribute load and prevent cumulative strain.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKECopying a professional rider's aggressive position.
FIXPros have spent years building the flexibility and core endurance for extreme positions. An amateur dropping to the same bar height without that preparation is asking for back pain. Start with a comfortable position and lower gradually over months.
MISTAKEIgnoring core work because you ride a lot.
FIXCycling does not build the lateral and stabilising core muscles that protect the back. You need off-bike core work to develop the muscular endurance that prevents pelvic rocking and lumbar fatigue.
MISTAKEBlaming the bike when the problem is flexibility.
FIXIf hamstring and hip flexor tightness limit your range of motion, no amount of bike fit adjustment can compensate fully. Address flexibility alongside fit for the best outcome.

FAQ

FREQUENTLY ASKED QUESTIONS

Can cycling cause a herniated disc?

Cycling alone rarely causes disc herniation in a healthy spine. However, sustained flexion combined with a weak core can aggravate a pre-existing disc issue. If you have a diagnosed disc problem, consult a physiotherapist before committing to long rides.

Is a more upright cycling position better for my back?

For most recreational riders, yes. A higher handlebar position reduces lumbar flexion and decreases the load on the lower back. The aerodynamic cost is negligible at amateur speeds.

Should I stop cycling if my back hurts?

Not necessarily. If the pain is mild and improves with position changes, adjust your bike fit and add core work. If the pain is severe, radiates into the leg, or does not improve with fit changes, see a physiotherapist before continuing.

Does cycling strengthen or weaken the back?

Cycling primarily works the legs and cardiovascular system. It does not significantly strengthen or weaken the back. The key is supplementing cycling with core work that supports the spine during the sustained forward-flexed position.
