🦴 Running isn’t the bone-building exercise you think it is.
As a health professional working with runners, one injury I hate seeing is a bone stress injury. It means weeks (frequently months) off running, and a long road back to fitness.
But here’s the kicker:
Running doesn’t do a great job of building strong bones.
Sure, it’s weight-bearing — but that’s not enough.
Running involves repetitive, low-to-moderate impacts in a single direction. Your bones quickly become desensitised to that stimulus. After just 100 cycles, bone cells stop responding (Burr 2002) — which means most of your run isn’t actually making your bones stronger.
🧠 Bones love novelty and high force.
They respond best to:
✅ Jumping & hopping (especially with changes in direction)
✅ Heavy strength training (think squats, lunges, deadlifts)
These apply varied, high-impact, multi-directional loads, which actually stimulate bone growth and resilience.
👉 So if you’re a runner, don’t just run.
Lift. Jump. Move in new directions.
Your bones will thank you — and you’ll spend more time running, not rehabbing.
Runners & health professionals, what are your favorite bone building exercises?
