Moving Gently
Stairs are the cheapest training in the building
A flight of stairs demands more effort per minute than almost anything else in an ordinary day, and it is already there. The barrier is the lift beside it.
What follows is the working version of using stairs: the decisions in the order you actually meet them, with the reasoning attached.
Before you start
- Climbing stairs is a high-effort activity available without equipment or time set aside.
- Descending loads the muscles differently and is where most soreness and most slips come from.
- Short bursts accumulate, which suits buildings where nobody has ten spare minutes.
Why a flight of stairs is unusually demanding
Climbing lifts your entire body weight against gravity repeatedly, which is a considerably higher demand per minute than walking on the level. The effort concentrates in the largest muscles in the body, and those muscles respond to being loaded regularly even in very short doses.
Because the effort is high, the useful dose is measured in flights rather than in the half hours associated with formal exercise. Breathlessness on stairs is one of the most common everyday markers people use to notice a change in their own fitness. It is also one of the few forms of activity that requires no clothing change, no equipment and no separate time in the day.
Going down is a different exercise
Descending uses the same muscles while they are lengthening under load, which is a different demand from the shortening contractions used going up. That kind of loading is strongly associated with the muscle soreness that shows up a day or two later, particularly after unaccustomed descents. It is also the direction in which most falls happen, because balance is harder to control and momentum is working against you.
A handrail is worth using habitually rather than only when needed, since the habit is what makes it available at the moment a foot slips. Anyone with knee pain will usually notice it more going down, which is a common pattern and one to raise with a clinician rather than push through.
Accumulating rather than scheduling
Two flights taken several times a day amount to a meaningful weekly total, and none of it requires a decision to exercise. The accumulation model suits people whose days have no available half hour, which describes a great many people who are told to find one.
On an ordinary week, stopping the lift a couple of floors early converts a habit into a smaller and much more sustainable change than banning it entirely. The effect fades when the building changes, so anyone who moves office or home should expect to rebuild the habit deliberately. Counting flights for a week is a useful diagnostic, and the number is usually either surprisingly high or surprisingly close to zero.
Building it into the day without theatre
The decision happens in the lobby, so it is settled far more reliably by a rule than by intention at the moment of arrival. A rule of the form "up to three floors is always stairs" removes the negotiation and adapts automatically to different buildings. Carrying a bag makes the climb harder and is not a reason to avoid it, though it is a reason to hold the rail on the way down.
Put simply, doing it in ordinary shoes is fine, and shoes with a very high heel or a loose fit are the exception worth respecting.
People often stop because they arrive somewhere warm and slightly out of breath, which is worth planning around rather than treating as a defeat.
Using them deliberately
For anyone who wants more than incidental benefit, repeated climbs of a few flights with a walk down between them is a genuinely demanding session. The intensity is easy to adjust by changing pace rather than distance, which makes it usable across a wide range of fitness levels.
In practice, taking two steps at a time increases the demand on the hips considerably and is worth adding gradually rather than immediately. A stairwell is free, weatherproof and available at odd hours, which are three practical advantages over most alternatives. Building up slowly matters, since stairs feel manageable during the session and produce soreness afterwards in people unused to them.
Where caution is warranted
Anyone with a heart or lung condition, significant joint pain or balance problems should get specific advice before increasing stair work substantially. Chest pain, unusual breathlessness or dizziness on stairs is a medical matter and not something to work through gradually.
Poor lighting, worn treads and carrying items that obscure your view of the steps are the ordinary hazards, and they cause more injuries than exertion does. Older adults benefit particularly from maintaining stair capacity, because losing it changes which homes and which places remain accessible. Where stairs are genuinely not an option, the same principle applies to any short repeated effort, such as walking up a slope.
The takeaway
The lift saves you ninety seconds. The stairs are the only training in the building.
The version you keep doing is the version that works.
Questions readers ask
How many flights a day is worth aiming for?
There is no established figure, and the useful approach is counting what you currently do and adding a few flights rather than chasing a target from a poster.
Why are my legs sore the day after stairs?
Descending loads muscles while they lengthen, and that pattern is the one most associated with delayed soreness, which settles as the activity becomes familiar.
