The short answer
- Stairs count as real exerciseThe NHS counts walking up stairs as vigorous-intensity exercise, and it is weight-bearing, which is the kind that helps keep bones strong.
- They ask more of balance and joints than flat groundA recent fall, unsteadiness or a knee or hip that flares on stairs are reasons to take more care, not reasons to give up the stairs altogether.
- A few changes make the same staircase saferA handrail on both sides, good lighting at both ends and a clear tread are the changes that matter most, and none of them cost much.
- There are good alternatives if stairs are not right just nowWalking, light weights and swimming all build the same strength and fitness with less strain on unsteady balance or sore joints.
None of this is medical advice for a specific person. If you are not sure whether stairs are safe for your parent, the GP or a physiotherapist can say so after seeing them, and that is worth asking for rather than guessing.
What stairs are good for
Why climbing stairs can be worthwhile exercise
Stairs use the legs to lift the whole body weight upward, over and over, which is harder work than it looks and asks more of the muscles and bones than a flat walk does.
Leg strength and bone health
Weight-bearing exercise
A workout for the heart and lungs
Counts as vigorous intensity
No equipment, and it is already there
Free, at home
It keeps a daily task manageable
Practical, not just fitness
None of this means more stairs is automatically better. The next section covers who should be more careful, and why that is not the same as saying stairs are a bad idea.
When to be more careful
Stairs ask more of balance and joints than flat ground
A flight of stairs is one of the more demanding things an older person does in an ordinary day, because it needs strength, balance and steady footing all at once. That is exactly why it is worth knowing the signs that call for more caution, rather than finding out from a fall.
Worth a closer look before stairs become a regular exercise

Balance and falls
Joints and breathing
None of these signs mean stairs have to be avoided altogether. They mean it is worth asking a GP or physiotherapist what level is safe, in the same way you would before starting any new exercise, and being more deliberate about the safety points in the next section.
Making the stairs safer
The changes that make the biggest difference
Most stair falls trace back to a handful of things: poor lighting, nothing to hold onto, something left on a step, or a loose mat at either end. Fixing those does more for safety than anything about how the stairs are climbed.
- Top and bottom
A light switch at both ends
So nobody starts down, or steps off at the bottom, without seeing the step clearly first.
- Both sides
A handrail the whole way, on both sides if you can
One rail is enough to start with. A second on the open side gives a hand to reach for at every step, not just the ones nearest the existing rail.
- Every tread
Nothing on the steps, and worn carpet or edges fixed
Shoes, post, laundry, a trailing cable. One item left on a step is enough to cause a fall.
- Top and bottom
Rugs and mats moved well clear
A loose mat at either end is one of the most common causes of a stair fall in the home.
- On your feet
Proper shoes or slippers with a back and a grip sole
Socks alone, or backless slippers, are worth changing before the stairs become the daily exercise.
A carer's visit can also cover this without it becoming a separate task: staying nearby while your parent uses the stairs, prompting the handrail, and noticing early if the stairs have become a struggle rather than exercise. Hourly carers on PrimeCarers who help with this charge £18 to £25 an hour with our fee included, against £28 to £35 an hour through most agencies. Personal care covers what else this kind of visit usually includes, and mobility and falls care goes further into reducing falls risk around the whole home.
If stairs are not right
Alternatives that build the same fitness more gently
If a GP has advised caution, or the stairs simply do not feel safe yet, the fitness stairs offer is not exclusive to them. These build similar strength and cardiovascular fitness with less demand on balance and joints.
Walking on the flat
Lower impact, still counts
Light weights or resistance bands
Seated or standing
Swimming or water exercise
Almost no joint strain
Tai chi, yoga or a chair-based class
Balance and steadiness
Whichever of these fits best, the NHS guidance for people over 65 is 150 minutes of moderate activity a week, or 75 minutes of vigorous activity, plus strength and balance work on at least two days a week. Stair climbing counts as vigorous intensity under the NHS's general activity guidelines. If poor posture is making stairs feel harder than it should, how do I stop stooping in old age? covers exercises for that specifically.
Questions
Questions families ask about stairs and exercise
Yes, for most people who are already steady on their feet. Stairs are weight-bearing exercise, which helps keep bones strong, and the NHS counts walking up stairs as vigorous-intensity exercise, meaning it gives a real cardiovascular workout in a short time. It asks more of balance and joints than walking on the flat, so it suits some people better than others.
Stairs can make existing osteoarthritis pain feel worse, because bending the knee under load is one of the movements that tends to hurt, but this does not mean the stairs are damaging the joint further. A handrail, and going up leading with the stronger leg, both make it more comfortable. Anyone with joint pain that stairs make noticeably worse should mention it to a GP or physiotherapist.
Stairs are one of the more common places for a fall at home, alongside loose rugs and poor lighting. Around a third of people over 65, and around half of people over 80, fall at least once a year according to NICE guidance, and a handrail, good lighting at both ends of the stairs and a clear tread are the changes that reduce that risk most.
Not necessarily, but it is worth asking a GP or physiotherapist first rather than deciding alone. A fall often means something has changed, whether that is balance, medication or a new health condition, and knowing what changed matters more than avoiding stairs on principle. What to do if a fall happens covers the steps to take afterwards.
Walking on the flat, swimming, light resistance training and tai chi or yoga classes all build similar strength and fitness with less demand on balance or sore joints. Any of these count towards the same weekly activity guidance that stairs do.
A handrail on both sides if possible, a light switch at the top and bottom, nothing left on the steps, and rugs or mats moved well clear of the top and bottom are the changes that matter most. If a rail is not enough, the local council can arrange a home safety visit and advise on further changes.
