This guide explains how to approach knee and leg exercise safely and when to seek an assessment, with recommendations grounded in public-health guidance.
Why muscle strength and balance matter
Stronger muscles around the knee, including the thigh muscles, can support movement and help absorb impact. The health guidance below provides general context; it is not a personalized treatment recommendation.
What health sources support
- The World Health Organization recommends that older adults who are able to do so build up moderate-intensity aerobic activity and include strength and balance activities, adapted to their ability and health conditions.
- Strength and balance activities can help maintain the ability to carry out daily tasks. A single exercise is not a vaccine against falls and does not treat joint disease.
- Consider an assessment before increasing exercise intensity if there is sudden pain, swelling, a locked joint, repeated falls, or unsteadiness while walking.
How to apply the guidance
- Start with activity you can do safely and increase it gradually. Ask a physiotherapist or doctor for guidance if you have limitations.
- Choose movements that work the leg muscles, balance, and everyday function. Use a stable support if you may fall.
- Also consider footwear, home surfaces, medicines, eyesight, and fall history. Fall prevention does not depend on one exercise alone.
