Taking the stairs, is it a real workout? Yes for your breath, provided you put intensity into it: three climbs of 20 to 60 seconds, three times a week for six weeks, increased VO2max by 7 to 12% in sedentary individuals. A few minutes of stairs after a meal also lower blood sugar, especially in diabetics. Large cohort studies link floors climbed to fewer deaths, without being able to prove the cause. For weight loss, on the other hand, almost nothing. Here is what twenty-two studies measure.

Breath: what the trials show

The first trials had people climb long stairs several times a day. In 15 sedentary young women, climbing a 199-step staircase up to five times a day, five days a week for eight weeks, increased VO2max by 17.1% and lowered LDL cholesterol by 7.7%, with no change in total cholesterol, HDL, or triglycerides. In a similar trial on 22 young women, seven weeks of the same type increased HDL and lowered the total cholesterol/HDL ratio; during a standard stair test, the heart beat slower and lactate was lower.

Lower volume works too. In 45 sedentary office workers, up to three climbs of 145 steps per day, five days a week for eight weeks, gained 9.4% in estimated VO2max — but nothing on blood pressure, blood lipids, or body composition.

Recent trials go shorter and harder. In sedentary women, three all-out efforts of 20 seconds on the stairs, three times a week for six weeks, increased VO2max by 12%; three 60-second efforts climbing up and down a single flight of stairs, by 7%. Three vigorous climbs of a 60-step staircase, spread throughout the day with 1 to 4 hours of rest between them, three days a week for six weeks, also improved VO2max compared to the control group, with an increase that the authors themselves consider modest.

Four trials in sedentary adults, 2005 to 2024

Compared to classic cardio, stairs hold their own. In 42 inactive young adults, three all-out climbs of 30 seconds (six flights, 126 steps), three times a week for six weeks, increased VO2max by 7%, whereas 40 minutes of moderate-intensity cycling at the same pace did not change it significantly; fat-burning capacity, on the other hand, did not budge in either group. In patients with coronary heart disease, interval climbs gained as much as moderate exercise in cardiac rehabilitation (from 21.4 to 25 mL/kg/min), with 7.1 minutes of total effort versus 36.7.

Climbing at your own pace is not always enough

In 22 slightly overweight sedentary men, twelve weeks of treadmill walking five days a week, plus 50 floors climbed per week at their own pace, did not improve VO2max, weight, or fat mass; diastolic pressure even rose by 6 mmHg during the exercise period, which the authors did not expect. Trials that improve breath all require vigorous or all-out climbs, not a walk up the stairs.

After the meal: blood sugar

A review of 25 studies concludes that short stair sessions lower post-meal blood sugar in prediabetic or type 2 diabetic individuals in 8 out of 9 studies; the effect on post-meal blood fats and that of several weeks of training remain to be clarified. In 16 type 2 diabetics, three minutes of stair climbing and descending, 60 and then 120 minutes after the meal, lowered the area under the blood sugar curve by 18%. In glucose-intolerant middle-aged men, about six minutes, started 90 minutes after the meal, accelerated the drop in blood sugar, at an intensity that remained moderate.

In healthy people, it is less clear. Breaking up nine hours of sitting with eight climbs of 15 to 30 seconds, one per hour, changed nothing in 12 normal-weight young men; in 11 overweight adults, insulin dropped by 16.5% and blood fatty acids by 21%, but not blood sugar. In 30 participants, ten minutes of ascending and descending after the meal lowered blood sugar equally in men and women. In 28 sedentary young adults, two minutes of stairs every 30 minutes after lunch altered blood sugar over the next two hours, with no effect on attention. For the same idea on the flat, see walking after the meal.

What large cohorts say

A meta-analysis of 9 studies and 480,479 participants, published in 2026, associates stair climbing with 39% less cardiovascular mortality (relative risk of 0.61) and 24% less all-cause mortality (0.76). In 8,874 former Harvard alumni followed for 12.4 years, climbing at least 35 floors per week was associated with a 16% lower risk of death than fewer than 10 floors. In the UK Biobank, in 280,423 participants, more than five flights per day at home were associated with fewer premature deaths, with the lowest risk observed between 6 and 10 flights (−9% all-cause, −12% for cancer).

Still in the UK Biobank, in 458,860 adults followed for 12.5 years, climbing stairs 11 to 15 times a day was associated with 22% less atherosclerotic cardiovascular disease than never climbing them; from 1 to 5 times a day, no difference. In adults with or at risk for knee osteoarthritis, climbing at least 7 flights per week was associated with a 38% lower risk of death over 13 years, and having difficulty climbing stairs with a 54 to 84% higher risk.

Did you know?

In the British cohort of 458,860 adults, participants who climbed stairs at baseline and then stopped five years later had 32% higher risk of cardiovascular disease than those who never climbed any. This is only an association, but it says that habit matters as long as you keep it.

The heart, precisely: studies contradict each other

The 2026 meta-analysis finds fewer cardiovascular deaths; two of the largest cohorts do not. In Harvard alumni, no link appeared with cardiovascular mortality, and in the UK Biobank neither: the authors judge the link with deaths to be weak and perhaps due to other differences between people. All these cohorts rely on floors reported by the participants. The trials themselves last four to twelve weeks and include 12 to 45 people, mostly young sedentary individuals, often women.

Weight, mood: very little

In a pilot trial on 26 overweight or obese women, four weeks of three 20-second climbs, five times a week, moved weight from 66.5 to 65.2 kg and waist circumference from 78 to 76.5 cm, with VO2max going from 31.6 to 34.9 mL/kg/min; but in office workers body composition did not budge. On the brain side, in 28 older adults, a session of interval stairs improved cognition only barely significantly, and participants felt more tired afterwards, no better mood.

Pushing oneself to take the stairs

A review of 16 studies finds strong evidence that a sign placed at the point of choice, near the elevator or escalator, gets people to take the stairs more often. Repainting the stairwell or adding music to it has not been studied enough to know if it helps.

In practice

For your breath, the protocols that work take just a few minutes: three all-out climbs of 20 to 30 seconds, or three vigorous three-flight stair climbs, three days a week, for at least six weeks. This is a form of interval training, see what HIIT does and improve your cardio. If you have diabetes or blood sugar that spikes after meals, a few minutes of stairs one to two hours after a meal have proven effective. On a daily basis, every flight counts with your daily steps. To fit these sessions into your week, the workout generator helps you; for weight, the calorie calculator decides.

In short

Your question	What the studies say
Do stairs improve breath?	Yes: 7 to 17% VO2max in 6 to 8 weeks in sedentary individuals
At what intensity?	Vigorous or all-out; at your own pace, one trial finds nothing
How much time per session?	Three climbs of 20 to 60 s, three times a week, were enough
As good as cycling?	As much or better, in much less time, in two trials
And blood sugar?	Down after meals in diabetics; less clear in young lean individuals
Do you live longer?	Cohorts suggest it, without proving it; the heart is debated
Does it make you lose weight?	Very little: 1.3 kg in one month in one trial, nothing in another

A few intense climbs a week are enough to improve your breath: fit them into your program.

Every figure in this article comes from a study you can open: the underlined mentions lead to the summary of the work it is taken from, written from the abstract alone. Mortality results come from observational studies, which show a link and not proof of cause. All-out climbs push the heart rate very high: if you have a heart condition, knee pain or if you haven't done any sports for a long time, talk to your doctor before getting into it.
