That twinge in the knee going down stairs or standing up from a chair — most of us know it. When knees hurt we want to move less, but weak muscles around the knee (especially the thighs) actually make the pain worse. Here are five moves that strengthen the surrounding muscles without stressing the joint.
Before you start: these are low-load moves that don't bend the knee deeply. Stop if you feel sharp pain or swelling, and check with a professional first if you have a knee injury or arthritis.
① Quad set (thigh squeeze)
With the leg straight, tighten the front-thigh muscle and press the back of the knee down. The joint barely moves, so you can safely activate the muscle even with some pain.
② Straight leg raise
Lie down with one knee bent; keep the other leg straight and lift it about 30cm, then lower slowly. You load the thigh hard without bending the knee.
③ Seated knee extension
Sit upright on a chair and slowly straighten one knee to horizontal, hold 2 seconds, and lower. Slow and controlled — no swinging — is the key.
④ Wall sit (shallow)
Back against a wall, slide down only to a shallow depth where the knees don't pass the toes, and hold. Deeper if pain-free, shallower if it hurts — match your knee.
⑤ Calf raises
Standing, rise slowly onto your toes and lower. Strong calves and ankles reduce the impact reaching the knee. Hold a wall or chair lightly if you feel unsteady.
When and how much
Every other day, 3–4 times a week is enough. Muscles get stronger during rest, so don't overdo it daily. Build up reps within a pain-free range.
Habits that protect your knees
- Going down stairs strains the knee most — hold the rail and go slow.
- Avoid prolonged squatting or sitting cross-legged.
- Extra weight means extra knee load, so keep a healthy weight.
FAQ
Can I exercise if my knee hurts?
For a dull ache, low-load moves actually help. But stop and get checked if there's sharp pain, swelling or heat.
What about stairs or hiking?
Downhills and descending stairs strain weak knees most. Strengthen the surrounding muscles first, then increase gradually.
Rest isn't the only answer for knee pain. Strengthening the muscles around it is the surest way to protect the joint.
