Knee exercises for runners

These knee-strengthening exercises will help with your running, strengthen the muscles around the knee and prevent knee pain.

The exercises strengthen all the muscles supporting the knee and stretch out the iliotibial band, known as the ITB, which runs down the outside of the thigh.

They can be done as part of your warm-up before a run or as a cool-down routine after a run, outside or indoors, or whenever is most convenient.

Typically, you should start to see some benefits after 2 weeks of doing these knee exercises every day.

You should not feel any pain when doing these exercises. If you do, stop immediately and seek medical advice. These exercises are not suitable for people with an existing knee injury.
