Improve joint health
Your knee is designed to be used. It needs movement and load to stay healthy. Movement and weight-bearing activities help to nourish the cartilage and strengthen the bone. It is fine to feel some pain while doing this.
Many people worry that they will wear their joint out if they use it too much. Research shows exercise does not wear out cartilage.
Movement is also great for the tissues around the joint and muscle strength. Stronger muscles around the joint reduce the problems of OA.
