Exercise is great. It helps keep our hearts healthy and keeps our blood moving. Unless your doctor specifically tells you to avoid certain kinds of exercises, get moving. Swimming is a great way to get cardio while being low impact on your legs.
Also standing up periodically and walking around for a few minutes if you sit for long periods of time is very good to prevent clot formations. Sitting with your legs propped up is a great way as well to reduce any swelling and help move blood from your legs.
