arthritis and exercise

adnil17

I suffer from arthritis in my knees, wrists and chest area. Normally I can do anything with minumal pain and stiffness. But in this cold weather it is getting too sore. i try gentle walking and try not put too much stress on my knees.

What can I do to keep exercising so i do not gain weight. I am not confident about swimming as i look awful in a costume.
