|of adults DO NOT meet the guidelines for both aerobic and muscle-strengthening activities. |
|When a person misses important social or professional obligations so they can workout; feels extremely sad or guilty when they don’t exercise; doesn’t give their body time to recover after an intense workout; or continues to exercise despite illness or injury, it is called compulsive exercise, or exercise addiction. |
|of people meet the criteria for behavioral addiction to exercise. |
What is the recommended amount of exercise?

|Moderate-intensity aerobic activity (heart rate is raised, light sweating, should be able to talk but not sing)||Vigorous-intensity aerobic activity (heart rate is raised significantly, heavy sweating, can’t say more than a few words at a time) .|
2 or more days per week
|Muscle-strengthening activities that work all major muscle groups (legs, hips, back, abdomen, chest, shoulders, and arms)|

How is exercise related to mental illness?
|Sedentary lifestyle may be a symptom of depression or anxiety when coupled with withdrawal from activities that one used to enjoy or social isolation. Additionally, living a sedentary lifestyle increases a person’s risk of developing depression.|
|When compulsive exercise is used as a way to “purge” calories that have been consumed, it can be a symptom of an eating disorder. |
|Eating disorders often accompany exercise addiction. Approximately 39-48% of people who have an eating disorder also struggle with exercise addiction. |
If you’ve been living a sedentary lifestyle and want to get started with an exercise program:
- Talk to your doctor to see if there are any special considerations you should take when exercising.
- Start slow and work up to harder activities.
- Find a friend to exercise with to keep you motivated and accountable.
Take control of compulsive exercise
- Take days off from exercising or substitute your normal routine with less strenuous workouts.
- Remind yourself that a certain body type or weight will not automatically lead to happiness.
- Avoid negative self-talk like, “You’re a lazy slob if you don’t go to the gym,” or, “Nobody will want to date you with a body like that.”
- Make sure you are eating enough to fuel your body for exercise.
- Tell a trusted friend or family member about your struggles. Make plans to do something besides workout a couple of days each week.
- Know when to seek professional help.
