DOES CYCLING AFFECT BONE DENSITY AFTER 50?

By Anthony WalshRoadman CyclingUpdated 10 July 2026

ANSWER

No, cycling does not build bone density. Research consistently shows that competitive cyclists have 10-15% lower bone mineral density in the lumbar spine and hip than age-matched runners or even sedentary controls. Cycling is a non-weight-bearing activity that provides no impact or gravitational loading — the stimuli bones need to maintain or build density. For cyclists over 50, this becomes clinically significant because age-related bone loss is already accelerating. The solution is to add 2-3 weight-bearing or impact-loading sessions per week alongside your riding.

KEY TAKEAWAYS

Cycling is non-weight-bearing and provides no bone-building stimulus — bones need impact or gravitational loading to maintain density.
Competitive cyclists often have 10-15% lower lumbar spine and hip bone mineral density than runners, and sometimes lower than sedentary controls.
After 50, age-related bone loss accelerates (1-2% per year in women post-menopause, 0.5-1% per year in men), making off-bike bone-loading exercise essential.
Adding 2-3 sessions per week of walking, running, skipping, or resistance training provides the impact loading cycling does not.

WHO THIS IS FOR

IS THIS YOU?

Masters cyclists concerned about osteoporosis risk

You have been cycling for years and are aware that it is non-weight-bearing, and you want to know what the actual bone density evidence says and what to do about it.

Riders who have been told they have low bone density on a DEXA scan

A scan has shown osteopenia or osteoporosis and you want evidence-based guidance on exercise strategies to protect and rebuild bone density alongside your cycling.

THE ROADMAN VIEW

This is one of the genuine health blindspots in cycling, and it does not get talked about enough. Anthony has covered this on the podcast multiple times because the evidence is clear and slightly uncomfortable: cycling, despite being excellent for cardiovascular health, does nothing for your bones. And if cycling is your only form of exercise for 20-30 years, you may arrive at 60 with the bone density of someone who has been largely sedentary. That is not a scare tactic — it is what the DEXA scan data shows in long-term cyclists.

The good news is that the fix is simple and does not require you to become a runner. Walking briskly for 30 minutes, skipping rope for 5 minutes, or doing a short resistance training circuit 2-3 times per week provides the impact loading your bones need. You do not need to run marathons — even short bouts of impact activity stimulate bone remodelling. The key message for any masters cyclist is this: keep riding, but add something weight-bearing to your week. Your 70-year-old self will thank you.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Prof Craig SaleProfessor of human physiology, Nottingham Trent University
Our research has consistently demonstrated that road cyclists have significantly lower bone mineral density at clinically important sites — lumbar spine and femoral neck — compared to runners, footballers, and even non-athletes. The absence of gravitational loading in cycling means the skeleton receives no mechanical stimulus for bone maintenance. For masters cyclists, we recommend a minimum of 2-3 sessions per week of weight-bearing exercise, ideally including some impact activity such as brisk walking, skipping, or running strides.
Dr Kirsty Elliott-SaleProfessor of female physiology, Nottingham Trent University
Post-menopausal women who cycle as their primary exercise are at particularly high risk of low bone density because they face both the exercise-specific deficit and the accelerated bone loss from oestrogen decline. For this population, combining cycling with resistance training and impact activity is not optional — it is essential. A DEXA scan every 2-3 years is advisable for female cyclists over 50.

PRACTICAL APPLICATION

DO THIS WEEK

Add 2-3 weight-bearing sessions per week to your training programme
Brisk walking (30 minutes), skipping rope (5 minutes of intervals), or running strides (6-8 x 100 m) all provide impact loading that stimulates bone remodelling. Even short bouts of impact are effective — bone responds to peak force, not duration. Slot these into easy ride days or rest days without adding significant fatigue.
Include resistance training with bone-loading exercises
Exercises that load the spine and hip — step-ups, lunges, weighted carries, and single-leg press — stimulate bone density at the sites most vulnerable in cyclists. Two sessions per week of 20-30 minutes is sufficient. The loading needs to be progressive — increase resistance over time to continue stimulating adaptation.
Get a DEXA scan to establish your baseline bone density
A DEXA scan measures bone mineral density at the lumbar spine and hip — the sites most affected in cyclists. If you are over 50 and have been cycling as your primary exercise for 10+ years, a baseline scan is advisable. Repeat every 2-3 years to track changes and adjust your off-bike exercise accordingly.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKEAssuming that cycling protects bone health because it is exercise.
FIXCardiovascular fitness and bone health require different stimuli. Cycling builds an excellent heart and lungs but provides no bone-loading stimulus. Bones need impact (running, jumping, walking) or gravitational resistance (weight training) to maintain density. Add both to your weekly routine.
MISTAKEIgnoring bone density because you feel fit and healthy.
FIXLow bone density is asymptomatic until a fracture occurs. A long-term cyclist can feel strong, ride well, and still have osteopenia at the lumbar spine. The only way to know your bone density status is a DEXA scan. Early detection allows intervention before clinical osteoporosis develops.
MISTAKERelying on calcium supplements alone to maintain bone density.
FIXCalcium and vitamin D are necessary but not sufficient. Without mechanical loading, the body does not direct calcium to bone remodelling. Supplements support bone health only when combined with weight-bearing or impact exercise. Get adequate calcium (1,000-1,200 mg/day) and vitamin D (20-25 mcg/day) through diet and supplementation, and combine them with physical loading.

FAQ

FREQUENTLY ASKED QUESTIONS

How much bone density do cyclists lose compared to runners?

Research shows competitive road cyclists have 10-15% lower bone mineral density at the lumbar spine and 5-10% lower at the femoral neck compared to age-matched runners. Some studies show cyclists even score lower than sedentary controls, though this may be confounded by the lower body weight of competitive cyclists.

Can I reverse low bone density through exercise?

Moderate improvements in bone density (1-3% per year) are achievable through consistent weight-bearing exercise and resistance training, particularly when combined with adequate calcium and vitamin D. The rate of improvement is slower than the rate of loss, so prevention is more effective than reversal. Early intervention — starting weight-bearing exercise before density drops into the osteoporosis range — produces the best outcomes.

Should I get a DEXA scan if I am a long-term cyclist?

Yes, particularly if you are over 50 and have cycled as your primary exercise for 10+ years. A baseline DEXA scan establishes where you stand and whether intervention is needed. Discuss it with your GP — some will refer proactively for cyclists, others may need you to explain the cycling-specific bone density evidence.
