I've been a near-vegan for about 20 years, but have decided to become vegan after learning more about the dairy industry. I'm not super fit. I don't lift weights because of wrist, knee, and foot pain. However, I would like to try. My doctor says its nothing more than arthritis and weightlifting will help; but I don't know how to get started. If anyone has any advice I'd love to hear it. I'm a 40 year old female.
