Brisk walking: what counts as brisk, and why 100 steps a minute matters

“Walk briskly” is advice everyone has heard and few people can define. It turns out there is a measurable answer. Researchers had adults walk at different speeds in the lab, measured how much energy they burned, and tied it to cadence, the number of steps you take per minute. The headline number is easy to remember: 100 steps a minute.

The short version

• For adults aged 21 to 60, 100 steps per minute is the threshold for moderate intensity and 130 steps per minute for vigorous intensity.
• Public Health England defines brisk walking as at least 3 mph (about 4.8 km/h).
• The World Health Organization recommends 150–300 minutes a week of moderate activity for adults. Brisk walking is the easiest way to get there.

Where 100 steps a minute comes from

Exercise intensity is measured in METs. One MET is the energy you use sitting still; 3 METs is the start of moderate intensity and 6 METs the start of vigorous. In the CADENCE-Adults studies, people walked on a treadmill at a range of speeds while researchers counted their steps and measured their energy use:

Age	Moderate (3 METs)	Vigorous (6 METs)
21–40	100 steps/min	130 steps/min
41–60	100 steps/min	130 steps/min
61–85	100 steps/min	No clear threshold

For people aged 61 to 85, 100, 110 and 120 steps a minute lined up with roughly 3, 4 and 5 METs, so every extra 10 steps a minute makes a real difference to intensity.

Brisk for you: thresholds by age

That first table is absolute intensity, the energy you burn. But a fit 25-year-old and a 55-year-old don’t experience the same pace the same way. When intensity is measured against your own heart rate (relative intensity), the thresholds shift with age:

Age	Moderate	Vigorous
21–30	≥120 steps/min	≥135 steps/min
31–40	≥120 steps/min	≥130 steps/min
41–50	≥115 steps/min	≥125 steps/min
51–60	≥105 steps/min	≥120 steps/min
61–85	≥105 steps/min	≥115–120 steps/min

If you are young and fit, you may need well over 100 steps a minute to feel it. If you are over 60, 105 steps a minute already counts as a moderate workout for you.

Brisk walking speed: mph and km/h

Stride length depends on your height and legs, so the same cadence gives different speeds for different people. The 2024 Adult Compendium of Physical Activities links speed to intensity like this:

Speed	METs	What it feels like
2.5 mph (4.0 km/h)	3.0	Easy
2.8–3.4 mph (4.5–5.5 km/h)	3.8	Moderate
3.5–3.9 mph (5.6–6.3 km/h)	4.8	Brisk
4.0–4.4 mph (6.4–7.1 km/h)	5.5	Very brisk
4.5–4.9 mph (7.2–7.9 km/h)	7.0	Very fast
5.0–5.5 mph (8.0–8.9 km/h)	8.5	Extremely fast

Hills change the picture too: walking uphill at a 1–5% grade is 5.3 METs, and at 6–10% it is 7.0 METs.

What brisk walking does for you

• Lower risk of death. In a 2018 analysis by Stamatakis and colleagues, people who described their walking pace as brisk had a 24% lower risk of death from any cause than slow walkers.
• Walking speed is a vital sign. In a 2011 analysis by Studenski and colleagues, every 0.1 m/s faster walking speed was linked to about a 12% lower risk of death.
• How you step matters, not only how many. The average cadence of your best 30 minutes of the day (“peak-30 cadence”) is linked to lower risk independently of your total steps. In a study on dementia, the best results were seen at around 112 steps per minute.

These are observational studies, so they can’t prove that brisk walking alone causes the difference, but the direction is remarkably consistent.

How to measure your cadence

1. Start walking at your normal pace and warm up for a few minutes.
2. Count your steps for 30 seconds (every foot strike counts).
3. Multiply by 2. That’s your steps per minute.

If you’re under 100, try slightly shorter, quicker steps and a livelier arm swing with your elbows bent.

How much brisk walking a week?

The WHO recommends 150–300 minutes of moderate activity a week, which is 30 minutes of brisk walking on five days. If 30 minutes in one go is too much, 10-minute blocks work too. Want more variety? Japanese interval walking adds hard intervals to the same weekly time.

Brisk walking in Durma

Durma shows your steps per minute live as you walk and marks your current intensity as light, moderate or vigorous. A metronome and haptics help you hold a target cadence, and targets adjust to your age. Your weekly brisk minutes are tracked against a 150-minute goal.
