How Little Exercise Still Counts: 22 Minutes, Short Bursts, Weekends and Stairs

Four large studies using activity trackers point the same way: 22 minutes a day offsets long sitting, short bursts of effort count, weekend-only exercise works, and stairs add up.

Activity-tracker studies show that small amounts of movement are linked with lower risk. Sitting 12 hours a day was tied to higher mortality only in people getting under 22 minutes of moderate-to-vigorous activity daily; three 1-to-2-minute bursts of vigorous effort a day were linked with 38% to 40% lower mortality in non-exercisers; and exercise packed into 1 or 2 days lowered cardiovascular risk about as much as spreading it out.

The standard advice is 150 minutes of moderate activity a week. Many adults do not reach it, and a common reason is time. Four recent studies looked at what smaller or less conventional amounts of movement are associated with.

22 minutes a day and long sitting

An analysis of four cohorts measured activity and sitting time with wearable devices. Sitting more than 12 hours a day, compared with 8 hours, was associated with a 38% higher risk of death, but only among people who got less than 22 minutes a day of moderate-to-vigorous activity. Above that level, sitting time was not associated with higher risk.

Short bursts of hard effort

Researchers studied 25,241 UK adults who reported doing no leisure-time exercise. Some still had brief vigorous bursts in daily life, such as fast stair climbing or carrying heavy loads. Over an average of 6.9 years:

  • About three bursts a day, each lasting one or two minutes, was associated with a 38% to 40% lower risk of death from any cause and from cancer
  • The same pattern was associated with a 48% to 49% lower risk of cardiovascular death

Exercise on one or two days

Among 89,573 adults wearing accelerometers, people who did at least 150 minutes a week concentrated in one or two days had lower risks of heart attack, heart failure, atrial fibrillation and stroke than inactive people. Their risks were similar to those of people who spread activity across the week. For heart attack, risk was 27% lower in the weekend group and 35% lower in the regular group.

Stairs

In a study with a median follow-up of 12.5 years, people who climbed stairs 6 to 10 times a day had a 16% lower risk of atherosclerotic cardiovascular disease than those who climbed none. The authors summarized the threshold as more than five flights, roughly 50 steps, a day. People who stopped climbing stairs between surveys had a 32% higher risk than those who never did.

Keep it in proportion
All four studies are observational. People who move more may be healthier to begin with, so the figures describe associations, not guaranteed effects.

How to use this

  • Aim for at least 22 minutes of brisk movement a day
  • Take stairs quickly, carry groceries, and walk fast for short stretches
  • If weekdays are full, do longer sessions on the weekend and build up gradually
  • Add walking breaks during long sitting. See breaking up sitting
