Cycling keeps us healthy. It is good for our heart and mental health. Surprisingly, it is also good for our knees. A study says older cyclists have less knee pain. Researchers asked 2,600 people about their physical activity. They also took X-rays of the people's knees. The X-rays showed signs of knee problems.

A researcher was surprised by the research. She said cyclists were 21 per cent less likely to have knee problems. When we use our knees a lot, the joints wear out and become painful. Knee problems usually start when people are in their fifties. Cycling is a great way to stop us having problems with our knees.
