The 3 minutes you spend waiting for the elevator is enough time to climb 5 floors. On one side is a free "stairway gym," and on the other is brisk walking, suitable for all ages—between these two most everyday forms of exercise, which one is actually more "worth it"? A 2026 meta-analysis of 480,000 people has just provided new data: people who regularly climb stairs have about a 39% lower risk of cardiovascular death. Today we put stairs and brisk walking on the same scale.

A new study of 480,000 people: stair climbers have a 39% lower risk of cardiovascular death

A systematic review and meta-analysis published in August 2026 in the American Journal of Cardiovascular Drugs (Am J Cardiovasc Drugs) screened 1,873 studies and ultimately included 9 studies with a total of 480,479 people. The pooled results showed that, compared with not climbing stairs, daily stair climbing was associated with a 39% lower risk of cardiovascular disease death (RR 0.61, 95%CI 0.48-0.79) and a 24% lower risk of all-cause death (RR 0.76, 95%CI 0.62-0.94)[1].

This overlooked "gym" in the stairwell has quite impressive data. But brisk walking is no slouch either—a pooled analysis of 11 UK cohorts including 50,225 walkers showed that, compared with slow walking, brisk walkers had a 24% lower risk of all-cause death and a 21% lower risk of cardiovascular disease death[5].

Round 1: Efficiency per unit time—stairs are about twice as efficient as brisk walking

Climbing stairs involves fighting gravity to "move" the body upward, so the intensity is naturally high. According to the MET values in the Compendium of Physical Activities (1 MET ≈ the energy expenditure of sitting quietly): slow stair climbing is about 8.0 MET, fast stair climbing about 8.8 MET, while brisk walking at a moderate pace is about 4.3 MET and slow walking only 2.5 MET[6]. In other words, in the same 10 minutes, stair climbing burns about twice as much energy as brisk walking.

For people short on time, stairs offer better "time cost-effectiveness."

Round 2: They train different things

Stair climbing = combined cardio and strength training. A randomized trial in Northern Ireland had sedentary young women climb 199 public stairs every day, 5 days a week, gradually increasing from 1 trip per day to 5 trips per day. After 8 weeks: maximal oxygen uptake (VO₂max, the core indicator of cardiorespiratory endurance) increased by 17.1%, and bad cholesterol (LDL-C) decreased by 7.7%[2]. A "exercise snack" study from McMaster University in Canada also found that climbing 3 floors quickly (60 steps) 3 times a day, 3 days a week, significantly improved cardiorespiratory endurance in sedentary young adults after 6 weeks[3].

Brisk walking = steady, reliable cardiorespiratory maintenance. Brisk walking has a low barrier to entry and is easy to sustain. Data from 50,225 people show that even if total exercise volume is not large, picking up the pace to the point of "slightly panting, able to talk but not sing" is associated with a significantly lower risk of death[5]. It has little impact on joints, making it a safer choice for people with higher body weight, middle-aged and older adults, and people with cardiovascular disease.

Round 3: Scenarios and risks

Stair climbing is high-intensity and places demands on the knee joints, balance, and cardiovascular reserve: people with old knee injuries, obvious chest tightness or shortness of breath, or unstable blood pressure control are not advised to make stair climbing their main form of exercise. Going downstairs is especially hard on the knees, so taking the elevator down is an option. Brisk walking has almost no contraindications; a 15-minute walk after a meal can also help reduce postprandial blood sugar fluctuations.

A smart compromise is the "exercise snack": when sitting for long periods, take 15-30 seconds each hour to climb a few flights of stairs. A randomized crossover trial found that in overweight adults, interspersing 8 short stair-climbing bouts during 9 hours of sitting reduced the total postprandial insulin response by 16.5% and free fatty acids by 21%[4]—something you can do in the spare moments while waiting for the elevator or coffee.

Conclusion: It's not either-or; it's about combining them

Action suggestions: After work today, get off the subway one stop early and brisk walk that stop; starting tomorrow, for 3 floors or fewer, don't wait for the elevator. After a week, notice this: has your breathing during stair climbing become less labored—that's a sign your heart and lungs are getting stronger.
