Moderate exercise is safe for most people, but it's a good idea to talk to your doctor before increasing your activity. Anyone age 65 or older should talk to a doctor before exercise.
It can be hard to be active when you feel depressed or anxious or have a mental health problem. But activity can help you feel better, so do your best to find a way to be active. It's fine to start with small steps. You can build up from a few minutes a day.
Do your best to slowly work up to moderate activity for at least 2½ hours a week. Moderate activity means things like brisk walking, brisk cycling, or shooting baskets. But any activities—including daily chores—that raise your heart rate can be included. Find a pace that is comfortable. You can be active in blocks of 10 minutes or more throughout your day and week.
If you have problems exercising on your own, ask someone to exercise with you or join an exercise group or health club.
