# The 6-6-6 walking challenge: is it worth doing?

> Mostly. 6-6-6 is a 60-minute brisk walk at 6 am or 6 pm, with six minutes to warm up and six to cool down. The hour is well supported: six a week is more than the guidelines ask, at about 7,000 to 8,000 steps a session. The 6 o'clock isn't special, and nobody has studied 6-6-6 itself.

Every few months a walking routine goes viral with a number for a name. 12-3-30 was a treadmill. Japanese walking was three minutes fast, three minutes slow. The 6-6-6 challenge, which took off in early 2025, is the plainest of them: walk for an hour at 6 in the morning or 6 in the evening, with six minutes to warm up and six to cool down.

There's no study of 6-6-6 itself, and no scientist behind it. But each of its parts has been studied on its own, and they don't all hold up equally well. The hour is the part that does the work. The 6 o'clock is the part that matters least.

## What is the 6-6-6 walking challenge?

The core version has three sixes:

- **60 minutes** of brisk walking, at a pace you can keep up without stopping.
- **At 6 am or 6 pm**, so the walk has a fixed slot in your day.
- **6 minutes** of slow walking to warm up first, and **6 minutes** to cool down after.

Some versions add more sixes: walk on six days a week, keep going for six weeks, or swap the hour for six kilometres. Here's what a session looks like with the clock running from your front door:

| Part | Time | Pace |
|---|---|---|
| Warm-up | 0:00–0:06 | Easy, an amble |
| The walk | 0:06–1:06 | Brisk: talking is possible, singing isn't |
| Cool-down | 1:06–1:12 | Easy again, letting your breathing settle |

So the full session is 72 minutes. Six days a week, that's 7 hours and 12 minutes of walking, which is a lot to fit around a job, a commute and everything else.

## How much walking is that?

More than most people realise, and more than the guidelines ask for.

- **Minutes.** The WHO and the US guidelines ask adults for 150 to 300 minutes of moderate activity a week. Six brisk hours is 360 minutes, before you count the warm-ups.
- **Steps.** Brisk walking starts at about 100 steps a minute, so the hour alone is roughly 6,000 to 7,200 steps, and the warm-up and cool-down add about another 1,000. A session is worth around 7,000 to 8,000 steps, on top of whatever else you walk that day.
- **Distance.** At the average adult pace of about 5 km/h (3 mph), an hour covers 5 km. The six-kilometre version asks for 6 km/h, about 3.7 mph, which is a properly brisk walk for most people and a stretch for many. [What is the average walking speed?](https://www.getstepup.app/guides/average-walking-speed) has the figures by age.
- **Energy.** Walking at 3.5 mph uses about 4.3 times the energy of sitting still, so a 70 kg person burns roughly 300 kcal in the hour, a little less once you take off what they'd have burned anyway. The [steps to calories calculator](https://www.getstepup.app/tools/steps-to-calories) works out yours.

## What does the research say about each six?

**The 60 minutes: good evidence, with diminishing returns.** A 2015 study pooled six large US cohorts, 661,000 people in all, and compared how much they exercised in their free time with how long they lived. People who met the minimum guideline had a 31% lower risk of dying during the study than people who did nothing. People doing two to three times the minimum had a 37% lower risk, and three to five times, 39%. Six brisk hours a week works out at a little over three times the minimum, so 6-6-6 lands in that top band. Notice the shape, though: the first 150 minutes bought most of the benefit, and the next 200 or so bought a few points more. A 2023 review of 94 studies found the same curve, with even 11 minutes a day linked to a 23% lower risk.

**The steps: good evidence that 7,000 to 8,000 is plenty for most people.** A 2022 analysis of 15 studies found the risk of dying kept falling with more steps until about 6,000 to 8,000 a day for people over 60, and 8,000 to 10,000 for younger adults. A 2025 review of 57 studies found the curve for early death flattening between about 5,000 and 7,000 steps a day, with 10,000 adding only a little more. One 6-6-6 session gets most people there, which is the strongest case for doing it. [How many steps should I walk a day?](https://www.getstepup.app/guides/how-many-steps-a-day) goes through those studies.

**The 6 am or 6 pm: no good evidence either way.** The studies that looked at the time of day point in different directions. A 2024 UK Biobank study of nearly 30,000 adults with obesity found that those who did most of their brisk activity in the evening had the lowest risk of dying over the next eight years or so. A 2023 US study of 5,285 adults found that people who were active mostly in the morning had a lower BMI and waist size. Both were observational, so they can't separate the time from the kind of person who exercises then: the morning group in the US study, for example, was ten or more years older than the others. Neither looked at 6 o'clock in particular.

**The 6-minute warm-up and cool-down: harmless, and less important than they sound.** A 2018 review of cool-downs found they do little to prevent injury or speed recovery, though they don't hurt and some people feel better for them. For walking, the warm-up mostly lets you find your brisk pace without starting cold, and the cool-down lets your heart rate settle before you sit down. Six minutes is a sensible amount. It isn't a magic one.

**The six days and six weeks: not tested.** Six weeks is long enough to notice that walks feel easier and to build a routine. It isn't long enough to judge long-term effects on weight, blood pressure or anything else, and nobody has measured 6-6-6 against anything over six weeks or any other stretch.

## Which of the claims hold up?

| The claim | What the research says | Verdict |
|---|---|---|
| It meets the exercise guidelines | 360 minutes a week, against a guideline of 150 to 300 | **True** |
| An hour a day helps you live longer | Large cohort studies link it to lower risk, but most of the gain comes in the first 150 minutes a week | **Good evidence**, with diminishing returns |
| 6 am or 6 pm is the best time | Studies of time of day disagree, and none tested 6 o'clock | **Unproven** |
| The warm-up and cool-down prevent injury | Little evidence that cool-downs prevent injury; no harm in them | **Weak** |
| You'll lose weight in six weeks | About 300 kcal a session for a 70 kg walker; what you eat matters more | **Possible, not promised** |
| 6-6-6 has been studied | Its parts have; the routine hasn't | **No** |

## Is it worth doing?

Yes, if you can keep it up, and that's a bigger "if" than it looks.

The hour itself is good for you, and there's nothing in the routine that's risky for a healthy adult who already walks regularly. If you can give it 72 minutes, six days a week, you'll be doing more than the guidelines ask, and more than most people ever manage.

The trouble is the jump. Someone who walks 4,000 steps a day now would be asked to roughly treble that from the first morning. Their feet, shins and knees haven't done that before, and their calendar probably hasn't either. That's the pattern [Why fixed step goals fail](https://www.getstepup.app/guides/why-fixed-step-goals-fail) describes: a big round target, set from nowhere, that's missed by day four and dropped by day ten.

It also asks for more than you need. If your aim is health rather than a challenge for its own sake, 30 brisk minutes a day gets you most of the way: [What does walking 30 minutes a day do?](https://www.getstepup.app/guides/walking-30-minutes-a-day) shows what it adds up to. And if you want more benefit for your minutes, [Japanese interval walking](https://www.getstepup.app/guides/japanese-interval-walking) took 30 minutes, four days a week, and beat steady walking in trials.



## How do you try it without burning out?

1. **Find your starting point.** Look at your average daily steps for the past month in Apple Health. If you're well under 5,000, start with 20 or 30 minutes, not 60.
2. **Build the hour, don't start with it.** Add 10 minutes a week, or about 10% at a time, until you reach 60. [The 10% rule](https://www.getstepup.app/guides/raise-step-goal-10-percent) explains why a steady ramp beats a leap.
3. **Pick the time you'll keep.** The 6 is there to give the walk a fixed slot, and that part is worth keeping: a walk tied to the same time every day is easier to repeat. If 7:30 or your lunch break is what works, use it. Early on a winter morning it may be dark, so wear something bright. In summer, an evening walk around sunset is cooler, and the [Golden Hour walk planner](https://www.getstepup.app/tools/golden-hour) shows when the light is low where you live.
4. **Split it if you need to.** Two 30-minute walks or three of 20 count the same towards the guidelines. Walks after meals have an extra benefit: in a trial of people with type 2 diabetes, a 10-minute walk after each meal lowered blood sugar after eating more than one 30-minute walk a day.
5. **Check your pace is brisk.** You should be able to talk but not sing, at about 100 steps a minute or more. StepUp's [Tempo](https://www.getstepup.app/metrics/tempo) shows how brisk your walking is, and you can record each walk with its route for free.
6. **Plan your rest day.** Six days a week leaves one off, and you'll need it. If you miss a day, the next one doesn't need to be longer.

For a gentler first month, [A 30-day walking challenge you'll finish](https://www.getstepup.app/guides/30-day-walking-challenge) starts smaller and builds to a daily walk.

## Who should be careful?

Talk to your doctor before you start if you have a heart condition, high blood pressure that isn't controlled, diabetes treated with insulin, or problems with your joints or feet, or if you haven't been active for a long time. An hour of brisk walking every day is a large increase for most people, even though walking is gentle.

Pain is worth listening to. Some tiredness and stiff calves in the first week are normal; pain in one spot that gets worse as you walk, especially in the shin or foot, is a sign to cut back for a few days.

## The short version

- The 6-6-6 challenge is a 60-minute brisk walk at 6 am or 6 pm, with a 6-minute warm-up and cool-down.
- The hour is the part with evidence behind it. Six of them a week is more than the guidelines ask, and each session is worth about 7,000 to 8,000 steps.
- The 6 o'clock isn't special: studies of morning and evening exercise disagree. Pick the time you'll keep.
- The warm-up and cool-down are sensible, not essential.
- Nobody has studied 6-6-6 itself. If an hour a day is a big jump for you, build up to it over a few weeks, or know that 30 minutes gets you most of the benefit.

## Questions

### Does the 6-6-6 walking challenge help you lose weight?

It can help, but it isn't a weight-loss plan on its own. An hour of brisk walking burns roughly 300 kcal for a 70 kg person, so six sessions a week add up. Whether you lose weight depends mostly on what you eat, and nobody has tested 6-6-6 for weight loss.

### Is it better to walk at 6 am or 6 pm?

Neither has been shown to be better. One large study linked evening activity to the lowest risk of dying, and another linked morning activity to a lower BMI, but both were observational and neither tested 6 o'clock. Walk at the time you can keep to every day.

### How many steps is the 6-6-6 walking challenge?

About 7,000 to 8,000 steps a session. Brisk walking is about 100 to 120 steps a minute, so the hour is roughly 6,000 to 7,200 steps, and the warm-up and cool-down add about 1,000 more. That's on top of everything else you walk that day.

### Can beginners do the 6-6-6 walking challenge?

Yes, but build up to it. If you walk fewer than 5,000 steps a day now, start with 20 or 30 minutes and add about 10 minutes a week until you reach the hour. Jumping straight to 72 minutes a day is the quickest way to sore shins and a dropped challenge.

### Can you do the 6-6-6 challenge on a treadmill?

Yes. The hour of brisk walking is what counts, not where you do it. Set a speed where you can talk but not sing, and use the first and last six minutes at an easy pace. An incline makes it harder without walking faster.
