How much you move your body often signifies your mood. For example, you may be more active when hypomanic or manic, and less likely to move when depressed. If you make moving your body a part of your daily routine, you may find that, even when you're depressed, exercise may be the one thing you complete that day, which is at least one thing you can feel good about. When you're manic, exercise will take the edge off, release some of your excess energy, and help you concentrate.
