When you have depression or anxiety, exercise often seems like the last thing you want to do. But once you get motivated, exercise can make a big difference.

Exercise helps prevent and improve a number of health problems, including high blood pressure, diabetes and arthritis. Research on depression, anxiety and exercise shows that the psychological and physical benefits of exercise can also help improve mood and reduce anxiety.

The links between depression, anxiety and exercise aren't entirely clear — but working out and other forms of physical activity can definitely ease symptoms of depression or anxiety and make you feel better. Exercise may also help keep depression and anxiety from coming back once you're feeling better.
