Your activity level, from your steps

Count your steps, not your workouts. Under 5,000 steps a day is sedentary, even if you lift three times a week. 5,000 to 7,500 is lightly active, 7,500 to 10,000 is moderately active, and over 10,000 is active. Your workouts go on top, at their own cost.

Why do people pick the wrong level?

Many calculators describe their levels by exercise. Lightly active is light exercise one to three days a week. Moderately active is three to five days. So someone who lifts on Monday, Wednesday and Friday and sits at a desk the rest of the time picks moderately active, and gets a number hundreds of calories too high.

Judging your activity by your gym days is like judging your spending by your vacations. The vacation is the part you remember. The coffee, the groceries and the gas are most of the bill. Your workouts are a few hours a week. The other hundred-odd waking hours set the level.

What do the words mean?

The 2020 to 2025 US Dietary Guidelines define them in their calorie tables, and the definitions are about walking, not the gym:

• Sedentary: only the activity of ordinary daily life.
• Moderately active: ordinary life plus activity equal to walking about 1.5 to 3 miles a day at 3 to 4 miles an hour.
• Active: ordinary life plus the equal of walking more than 3 miles a day at that pace.

A brisk mile is about 2,000 steps. In tests gathered by a 2011 review, people took about 1,936 steps to walk a 15-minute mile. So moderately active means roughly 3,000 to 6,000 steps a day on top of the walking you’d do anyway. A 2004 review of pedometer studies found ordinary daily life, without sport or exercise, is typically 5,000 to 7,500 steps, and called under 5,000 a sedentary lifestyle.

Here are the bands our calculators use. The step bands come from that review, and the levels are the usual calculator scale.

A 30 minute walk at a moderate pace is about 3,000 steps, at the 100 steps a minute researchers use as the line for moderate walking. Nobody has published an official conversion from steps to these multipliers that we could find, so the bands are a mapping, and your scale is the check.

What do your workouts add?

Work out each session on its own. An activity’s cost is in METs, how many times your resting rate it burns. Lifting weights at an ordinary effort, several exercises at 8 to 15 reps, is 3.5 METs in the Compendium of Physical Activities. The calories on top of resting are (METs minus 1) × your weight in kg × hours.

At 180 pounds (82 kg), an hour of lifting is 2.5 × 82 × 1, about 205 calories. Three hours a week, spread over seven days, is about 90 calories a day.

Now the trap. A 40 year old man, 5 foot 10 and 200 pounds, walks 4,000 steps a day and lifts three hours a week. Sedentary plus his lifting gives a maintenance of about 2,290. The same calculator with “moderately active” ticked prints 2,826. His gym habit is real and worth keeping. It just isn’t worth 540 calories a day.

Runs and walks are already in your steps, so don’t add them twice. Cycling, swimming and rowing don’t show up as steps, so they go on top like lifting.

How many calories do your steps burn?

Walking at about 3 miles an hour costs 3.8 times your resting rate in the 2024 Compendium. At about 100 steps a minute, 1,000 steps take ten minutes, and the extra burn works out to about 0.2 calories per pound of you.

These are calories above what you’d burn sitting still. A heavier body pays more for the same walk, which is why the same step goal is worth more to some people than others.

The 10,000 number itself has no study behind its start. The 2004 review traced it to Japanese walking clubs and a business slogan from more than 30 years earlier.

Does more movement always add up?

Mostly, at the low end. Moving from sitting all day to walking daily raises your burn. In a 2016 study of 332 adults in five populations, daily burn rose with activity over the lower range and then levelled off in the most active people.

So count your workouts, and expect a bit less from them than the arithmetic says, mostly because you’ll get hungrier. Steps are the steadier lever, since you take them all day.

Where to find your steps

Your phone counts steps if you carry it, and a watch counts them if you wear it. A 2025 review of 56 Apple Watch studies found step counts mostly accurate, with some conditions missing by more than 10%. That’s close enough to pick a band. Use your average over two weeks, including weekends, since one busy day says little about your normal.
