The Everyday Exercise We Keep Ignoring

In a world engineered for convenience, the humble staircase is often overlooked. We always hear through sounds of elevators humming, escalators gliding, and we instinctively choose the option that requires the least effort.

And yet behind that ordinary set of steps lies one of the most accessible and underestimated forms of exercise available to modern humans.

Extreme examples like Sean Greasley’s 2021 world record, climbing the equivalent height of Mount Everest on stairs, may seem far removed from daily life.

But scientific evidence suggests you don’t need to chase records or sprint up skyscrapers to benefit. Even climbing a few flights a day can significantly improve physical health and sharpen the mind.

Researchers increasingly describe stair climbing as an “exercise snack”: short bursts of activity that fit naturally into daily routines.

These small choices, taking the stairs at work, at home, or in public spaces, may quietly deliver outsized benefits for cardiovascular health, muscle strength, balance, and cognitive performance.

The Science of Stair Climbing: What Really Happens

From a physiological standpoint, stair climbing is deceptively powerful, unlike walking on flat ground, it forces the body to work against gravity, rapidly increasing heart rate and oxygen consumption.

This elevated demand strengthens the heart and lungs, improving cardiorespiratory fitness in a way comparable to gym-based stair machines or brisk treadmill walking.

Lower-body muscles do most of the work. The quadriceps, glutes, calves, and stabilising abdominal muscles are heavily engaged, leading to increased muscle size, strength, and endurance over time.

Importantly, stair climbing involves two distinct types of muscle contractions:

• Concentric contractions when climbing upward, where muscles shorten under load

• Eccentric contractions when descending, where muscles lengthen while resisting gravity

Eccentric contractions, particularly during the descent, are associated with greater muscle strengthening and long-term energy expenditure due to muscle repair and adaptation.

Beyond muscles and the heart, stairs appear to have a surprising influence on the brain. Studies show that climbing just two flights of stairs can improve problem-solving, focus, and mental flexibility—sometimes more effectively than climbing many more flights.

This suggests the cognitive benefits are not about intensity alone, but about short, stimulating bursts of movement.

Psychological research points to improvements in executive functions, including task switching and inhibition—the brain’s ability to filter distractions.

These functions are essential for learning, decision-making, and creative thinking. In one study, participants who climbed stairs felt more energetic and happier immediately afterward, indicating a rapid mood-enhancing effect.

Scientists believe these cognitive benefits may be linked to increased blood flow to the brain and the release of growth factors such as Brain-Derived Neurotrophic Factor (BDNF).

This is a protein based factor that supports learning, memory, and neuroplasticity.

Exercise-induced boosts in BDNF may help the brain form new neural connections, explaining why even brief physical activity can sharpen thinking.

There is also emerging evidence that stair climbing may have delayed cognitive benefits.

When combined with good sleep quality, memory improvements have been observed the following day, suggesting that movement and rest work together to consolidate brain gains.

Small Steps, Long-Term Gains

While public health conversations often fixate on ambitious targets like 10,000 steps a day, stair climbing offers a more realistic and flexible alternative.

Research suggests that climbing as little as five flights of stairs daily—about 50 steps—may reduce the risk of atherosclerotic cardiovascular disease, a major contributor to heart attacks and strokes.

Of course, stair climbing is not a universal solution. Individuals with knee osteoarthritis or mobility limitations may find stairs painful, and not all studies agree that stair climbing alone is sufficient to reduce long-term mortality risk.

But for many people, it represents a practical way to interrupt sedentary habits without needing special equipment, gym memberships, or dedicated workout time.

The greatest strength of stair climbing lies in its simplicity. Stairs exist almost everywhere, and choosing them transforms an ordinary moment into a meaningful act of self-care.

Spread across the day, these “exercise snacks” are often more enjoyable and sustainable than single intense workout sessions.

And in an age where movement is increasingly optional, the staircase quietly waits, offering stronger muscles, a healthier heart, and a sharper mind to anyone willing to take the first step upward.

So instead of taking the elevator next time, why not try climbing a few stairs.
