Knee strengthening exercises

How can exercises help to strengthen our knees?

Regular strengthening exercises can help to build up the muscles in and around our knees. This can help improve the support around them, which can help to prevent injury and pain.

When starting any new exercise, you should always begin slowly and gradually. And, only do as much as you can manage without feeling any pain. Speak to your doctor or physiotherapist beforehand if you have an existing knee injury, or if:

• your knee pain is severe
• you feel that your knee is locked or ‘giving way’
• the pain lasts for a few weeks

What types of exercises can strengthen knees?

Below is a series of exercises that you can try at home or in the gym. It’s a good idea to spend five minutes warming up before performing these exercises. You could try 5 to 10 minutes of walking or cycling, for example.

Bodyweight squat

• Stand upright with your feet hip-width apart and your toes pointing forwards.
• With your back straight, chest out, and shoulders back and down, slowly squat downwards.
• Don’t let your knees move in towards each other.
• Squat downwards as far as you comfortably can, then straighten your legs to return to standing.
• Aim for 3 sets of 10 repetitions.
