Walking stairs and uphill:
how many calories and what the benefits are

Why climbing burns more

On a flat surface, you're only moving your body forward. On stairs and hills you add work against gravity: every step lifts your entire body weight up by the height of the stair. That vertical work is the source of the extra calories

In terms of intensity (MET): easy walking is around 3.5 MET, while climbing stairs is 8–9 MET. Put simply, in the same amount of time on the steps you spend 2–3 times more energy. For the full calorie math, see our piece on how many calories 10,000 steps burn

What it gives you

• More calories in less time. When you're short on minutes, hills and stairs are the fastest way to raise your burn
• Strong legs and glutes. Climbing specifically loads the quads, glutes and calves — it's almost strength work
• A heart workout. Your heart rate jumps quickly on stairs, so even short climbs do a great job building stamina and VO₂max
• Stronger bones. This is weight-bearing load against gravity — it stimulates bone density
• Gentler than running. Climbing has no hard, jarring landing like running does — the load is high but the impact on joints is low

Going down: where the risk to your knees hides

Climbing loads your muscles, but going down loads your joints. On the way down your muscles work in a "braking" (eccentric) mode, and the impact load on your knees is higher than on the way up. This doesn't mean descending is harmful — you just need to do it more carefully:

• Go down slowly and under control, don't "drop" from step to step
• Bend your knee slightly, taking the weight softly
• If your knees are sensitive — take the elevator down and walk up

Walking itself, stairs included, isn't harmful to healthy knees — we debunked that myth in our piece on whether walking is bad for your knees

Technique

• Place your whole foot on the step, not just the toe — it's more stable and puts less strain on your calves
• Push off through your heel and engage your glutes, rather than pulling yourself up by the railing
• Keep your torso upright, with a slight lean forward from the ankles and your gaze ahead
• Breathe steadily. If you're really out of breath — slow down, that's normal for a beginner
• The railing is for safety, not for shifting your weight onto it

How to fit it into your day

• Stairs instead of the elevator. The simplest start. Even a couple of floors several times a day add up — especially with a desk job
• "Stair snacks." 2–3 times a day, climb a few flights briskly — like in the study above
• A route with a hill. Plan your walk over a bridge, an embankment with a climb, or a hill in the park
• An inclined treadmill. On the treadmill, raise the incline — your burn goes up without running
• In the metro and malls, take the steps instead of the escalator

In spirit this is a "neighbor" activity to rucking and Japanese interval walking — different ways to add intensity to ordinary steps

Who should be careful

Climbing sharply raises your heart rate and blood pressure, so it's worth starting gradually, and if you have heart disease, uncontrolled blood pressure, problems with your knees or hips, or if you're pregnant — check with your doctor first. Knee pain on the way down is a signal to ease off, not to "push through"

Bottom line

Stairs and hills are a free way to get the most out of walking: 2–3 times more calories, strong legs, a trained heart and strong bones — all at low impact. And short 20-second "stair snacks" several times a day genuinely improve your fitness, as the research shows

The main thing is to build up gradually and protect your knees on the way down. Start with one rule: always take the stairs up. That alone is enough to make an ordinary day noticeably more active
