Two activities stand out for overall health: walking (or similar aerobic movement) and strength training. Health agencies advise both: weekly moderate aerobic movement plus at least 2 days of muscle‑strengthening, which together improve heart, blood sugar, bones, and function as we age (CDC guidelines).
Walking is one of the most proven ways to protect health. Regular walking is linked with lower risk of early death and many diseases, even at modest doses, as shown by large population studies and global health reviews (WHO fact sheet). Walking also helps with fat loss because it raises daily energy use and is easy to repeat day after day.
A new study suggests that intermittent walking, which means short bursts with brief stops, may increase the health impact of a simple walk. The research measured oxygen use, a stand‑in for energy burn, and found that many short bouts used more energy than the same distance at a steady pace. This article explains what that means for your daily walk, who might benefit, and the limits to keep in mind.
Intermittent walking burns more energy than steady pace
What the study tested
Researchers asked healthy young adults to walk in short bouts of 10 to 240 seconds on a treadmill and to climb short bouts on stairs. They measured oxygen uptake, which reflects how much energy the body uses. The team reported that 10–30 second bouts consumed about 20–60% more oxygen than continuous movement for the same distance, because starting from rest costs extra energy before the body settles into a steady state. You can read the Proceedings of the Royal Society B paper reporting higher oxygen use in short walking bouts on the publisher site Move less, spend more: the metabolic demands of short walking bouts.
Why starting and stopping costs more
When you go from still to moving, your muscles work harder to overcome inertia and to reach your chosen speed. Your heart and lungs also take a short time to reach a steady supply of oxygen. That ramp‑up phase uses more energy than cruising. Cars show a similar pattern: city driving with many stops usually burns more fuel than highway cruising at a constant speed.
What this could mean in real life
If you enjoy strolling, it may help to pause for a view, a chat, or a shop window, then start again. Those little restarts could raise total energy burn for the same distance. This idea pairs well with “movement snacks” across the day, like taking the stairs or doing short walks between tasks. For weight control, we have a related guide on walking for fat loss that explains why a repeatable daily walk helps many people keep weight off over time.
Intermittent walking vs step counts: what matters
Step targets are not magic
Common goals like 10,000 steps are easy to track but are not a hard rule for health. Large cohort work from the American Cancer Society suggests that even lower weekly walking totals link with longer life. What matters most is moving often in ways you can maintain for months and years. Intermittent walking can make that easier by adding variety and natural pauses.
Build a routine you can keep
Pick a route you like. Add small stops that make you smile. If you can, take a few short walks spread through the day. These choices can raise your daily non‑exercise movement, often called NEAT. For ideas, see our piece on walking as the simplest way to lose fat and keep it off.
Who intermittent walking may help most
People easing into activity
The study authors note that the stop‑start pattern could be useful for people with lower aerobic fitness and those who need more time to reach steady state. If brisk, long walks feel daunting, try brief strolls with pauses. Short bouts also fit well into rehab or return‑to‑activity plans designed by a clinician.
Active people and athletes
If you already run or walk fast for long distances without getting winded, intermittent walking is unlikely to add fitness benefits. For overall healthy aging, build strength too; see after 40, lifting weights is the best way to slow muscle loss. It can still add joy and reduce monotony. Keep your main training as advised by your coach or program.
Limitations and quality of evidence for intermittent walking
Evidence type and scope
The main study here is a human experiment in healthy young adults using indirect calorimetry (oxygen uptake) on treadmills and stairs. It is not a long‑term trial that proves better health outcomes. The 20–60% figure describes oxygen use during short, controlled bouts in a lab, not daily life across months.
What we do not yet know
We do not yet know whether stop‑start walking improves weight, heart health, or blood sugar more than steady walks over time. We also do not know the best pattern of bouts and rests for different ages or conditions. Future randomized trials in older adults or people with chronic disease would help test real‑world benefits.
Safety notes
If you have heart, lung, joint, or balance issues, ask your clinician how to adapt this idea. Use shoes that fit well, choose safe paths, and start with short, easy bouts.
How to try intermittent walking in simple steps
A short, practical plan
- Pick a 20–30 minute walk. Add a gentle stop every 1–3 minutes for 10–30 seconds. Look around, breathe, then start again.
- Break longer walks into “city blocks”: walk one block, pause at the corner, then go. On stairs, climb one or two flights, rest briefly, then climb again.
- Spread 3–5 mini‑walks across the day. Even five minutes with a couple of pauses counts.
Keep what works, drop what does not
This approach is a tool, not a rule. If stops make your walk more pleasant, keep them. If you prefer a steady, mindful pace, that is also great for health.
