Knee Strengthening Exercises

Knee strengthening exercises are one of the best ways to cure knee pain. People who do them have less pain, recover quicker from injuries, function better and have less chance of problems recurring in the future.

Knee strengthening exercises can be used to help relieve and sometimes even prevent various causes of knee pain. Whenever there is weakness in the leg muscles, it means the knee joint is less well supported, resulting in more weight going through the bones, therefore making knee problems much more likely.

Quads Knee Strengthening Exercises

Balance Retraining

Balance / proprioception is really important to prevent knee injuries. A quick way to tell whether you should be doing balance exercises as part of your knee strengthening exercises programme is to try standing on one leg with your eyes closed. If you can’t do it for one minute, you should do some balance exerices. This exercise helps your body learn the subtle adjustments needed for good balance.

Repetition: Spend 5 minutes doing this 2x daily e.g. when brushing your teeth

Progression: 1) Close your eyes and perform the exercise as above – you’ll be surprised how much harder it is

What Next?

 As your muscles get stronger, you will be able to increase the number of repetitions of each of these knee strengthening exercises.

You will probably need to do knee strengthening exercises at least four times a week for about a month before you notice much change in your knee pain at which point you may also want to add in some knee stretches (it’s important to have enough strength before you start stretching else you can make things worse).
