Staying active can help to reduce stiffness in your joints. You should move around often during the day and avoid staying in one position for too long.
Set yourself a target to move during the day. If you're sitting at a desk, take a walk around the office/garden for a few minutes every hour. If you're at home watching TV, walk around the house every time the adverts come on TV.
Adding in a little bit of movement during the day will really help your joints.
