How long should you walk to avoid chronic back pain? A 20-year study reveals the magic number

Walking 100 minutes a day may be your best shield against chronic back pain

You’ve probably heard it before—walk 10,000 steps a day and stay healthy. But what if we told you that the number of steps doesn’t matter as much as the time you spend walking? A groundbreaking new study says it’s not how far or fast you walk, but how long you keep moving that really counts—especially when it comes to preventing chronic lower back pain.

Researchers from Norway and Denmark followed over 11,000 adults for nearly two decades to answer a simple but powerful question: How much walking is enough to reduce your risk of long-term back pain? The answer? 100 minutes a day.

The surprising science behind the walking-back pain link

According to the study published in JAMA Network Open, people who walked for more than 100 minutes a day had a 23% lower risk of developing chronic lower back pain compared to those who walked less than 78 minutes daily.

"The reduction in risk leveled off beyond 100 minutes," researchers noted, suggesting there’s a sweet spot for maximum benefit.

✅ key findings:

• Walking more than 100 minutes a day significantly reduced the risk of chronic lower back pain.
• The benefit applied equally to men and women of all ages.
• Walking faster also helped, but duration mattered more than speed.
• After 100 minutes, the added benefit began to plateau.
• Participants who walked more also tended to be more physically active overall.

Why does it matter?

Chronic lower back pain—defined as pain lasting more than three months—is more than just uncomfortable. It’s one of the leading causes of disability and missed workdays worldwide. In the UK, 23.4 million working days were lost to musculoskeletal (MSK) conditions in 2022 alone. These issues now rank as the second top reason people are “economically inactive,” just behind mental health.

A public health strategy hiding in plain sight

Experts say these findings have massive implications for public health. Unlike expensive treatments or complicated exercise routines, walking is free, accessible, and effective.

“Our findings suggest that policies promoting walking could help reduce chronic back pain across populations,” the authors concluded.

In fact, the UK Government has already committed £3.5 million to improving MSK services. But with over 348,000 people waiting for NHS MSK appointments, prevention might be the most powerful treatment of all.

So, should you start walking 100 minutes a day?

The short answer: if you can, yes. The study suggests that even moderate-paced walking done regularly can keep your spine—and your life—more flexible and pain-free. However, researchers emphasize that walking is not a cure-all, and patients with existing back pain should consult healthcare providers before starting new routines.
