Fourteen steps up from the dock

THE 30-SECOND VERSION

Coming down stairs is harder on a knee than going up. The step-up, lowered slowly, trains exactly that. Use the bottom stair and hold the rail.

TODAY’S MOVE

Making peace with the stairs

Back to the knees, and to the complaint more of you named than any other.

There are fourteen wooden steps from the dock up to the parking lot at our marina. I have climbed them a thousand times. These days I notice them, and here is the odd thing I noticed: going up is fine. Coming down, carrying a cooler, my right knee complains the whole way.

That struck me as backward. Going up is the effort. Going down should be the easy half. When we last covered knees, more of you picked achy going down than any other answer, so plainly I am not alone in this.

There is a good reason for it, and once you know the reason, the exercise makes sense. Here it is.

Which is usually harder on a sore knee: going up stairs, or coming down?

Coming down

Going up

About the same

01

Pick a low step and a rail

Use the bottom stair of your staircase, with the handrail beside you. Keep a hand on that rail the whole time. Never do this on a wobbly stool or a loose box.

ⓘ Lower is better to start. A taller step raises the load through the knee sharply.

02

Step up with one leg

Place your whole foot on the step. Press through that heel and rise up, letting the other foot follow. Keep your knee pointing over your toes, not falling inward.

ⓘ Easier version: lean more weight through the handrail while you learn the pattern.

03

Lower yourself slowly

This is the important half. Step back down over a slow count of three, letting the leg still on the step control the descent. Do not drop or thud onto the floor.

ⓘ If you rush any part, rush the way up. Never the way down.

04

Build slowly, both legs

Start with five on each leg. Over the weeks, work toward two sets of ten. Do both sides, even if only one knee troubles you.

ⓘ Stop if the knee sharpens, buckles, or catches. Tired thigh muscles are fine.

✓✓ Some ache in the thigh the next day is the muscle working, and that is what we want. Sharp pain inside the knee joint is not. Lower the step, cut the number, and build back up.

THE WHY

Why down is harder than up

Going up, your thigh muscle shortens and lifts you. That is the ordinary way a muscle works, and it feels like effort. You get out of breath, but the knee is fairly happy.

Coming down is a different task. Gravity is pulling you toward the next stair, and something has to stop you falling into it. That something is the same thigh muscle, working while it lengthens. It acts as a brake. In other words, your thigh is paying out rope, slowly, with your whole body weight on the line.

Braking is the harder job, and it is the first thing to fade. Research on people with knee trouble finds exactly this pattern: the thigh does not brake as well on the way down, so the descent gets slow, careful, and sore. That is my cooler-carrying trip down the dock steps in one sentence.

So train the braking

That is the whole reason we lower slowly. Stepping up builds the muscle. Stepping down slowly teaches it to brake, which is the skill stairs actually demand. It is also why step height matters so much. Descending a taller step raises the load through the knee by roughly a third, so a low stair is not timidity, it is sense.

⚠ WHEN TO STOP

When to stop and call your doctor

These are uncommon, but they are signals to get checked rather than work through:

● A knee that locks, catches, or gives way under you, especially on stairs.

● A knee that is hot, red, and swollen, or a fever alongside the pain.

● Pain shooting down the leg, or new numbness or weakness in the leg or foot.

When in doubt, get it checked. PainFree adds to your doctor’s care. It never replaces it.

THIS WEEK’S QUICK WINS

Three ways to make stairs kinder

🛑 Lead with the sore leg going down

Going down, put the sore leg down first, so the good one does the braking. Going up, lead with the good leg. Some people remember it as up with the good, down with the bad.

Free • Works from the next flight on

🪛 Use the rail, and free your hands

Carrying a full laundry basket down a flight is the worst version of this. Make two trips, or use a bag over your shoulder, and keep one hand on the rail.

Every trip • A hand on the rail

⏱️ Practise on the bottom stair

You do not need a gym or a special box. The bottom step of your own staircase, with the rail right there, is the safest place to do today’s exercise. Five slow ones each leg.

2 minutes • The stair you already own

RESEARCH BRIEF

The braking muscle, and the step height

Studies of stair walking in people with knee arthritis find the same thing again and again. The thigh muscle does not brake well on the way down, so descent becomes slow and painful. Step height turns out to matter a great deal too. Research measuring joint forces found that coming down a step about half again as tall raised the peak load through the knee by roughly 30%. That is why we start on a low stair. And when researchers tested which measures best captured improvement in people with knee and hip arthritis, a step-up test did better than the familiar 30-second chair stand.

30%

more load through the knee coming down a taller step

25%

of adults over 55 live with persistent knee pain

3

seconds is the count that turns a step-down into training

A low step, lowered slowly, trains the exact job your knee struggles with. The height and the pace do the work.

MOVEMENT OF THE WEEK

The shallow wall sit

Where the step-up trains the thigh through movement, this builds its staying power while the knee barely moves. Good on days when the joint is grumpy.

1.	Stand with your back flat against a wall, feet about a foot forward.

2.	Slide down only a little, bending the knees just slightly. Do not go near a deep squat.

3.	Hold for 10 seconds, slide back up, and repeat 5 times.

HOW TO PROGRESS

Starting out

Tiny bend, 10 seconds

Building

20 to 30 seconds

Stronger

A slightly deeper bend

Keep the bend shallow. Deep knee bends load the joint hard and are not the point here.

WHAT THE EVIDENCE SAYS

Three ways to handle bad stairs

Strengthening the thigh

The best-backed answer, and free. Guidelines put exercise first for knee arthritis, and the thigh is the muscle that both lifts you and brakes you.

Technique and a handrail

Underrated. Leading with the right leg and using the rail cut the load on the sore side today, while the strengthening catches up over weeks.

Avoiding stairs altogether

The instinct that costs you. Skip stairs entirely and the braking muscle fades further, which makes the next flight harder still. Reduce, do not abandon.

Check with your doctor or a physical therapist before starting, especially after a knee replacement or a recent injury.

WORTH KNOWING

60%

Even after a knee replacement, around 60 in 100 people still find going down stairs difficult. That tells you something useful. A good deal of the trouble is muscle control, not the joint alone, and muscle control can be trained.
