(HealthDay News) -- There's nothing wrong with practicing healthy behaviors in moderation, and exercise is no exception. But you can overdo it.

The Nemours Foundation mentions these warning signs of being a compulsive exerciser:

• Refusing to skip a workout even when tired, injured or sick.
• Exercising out of obligation, rather than enjoyment.
• Doubling the length of a workout after missing one.
• Obsessing over weight and burning calories, along with weight loss.
• Increasing exercise to make up for eating more.
• Prioritizing exercise above seeing friends and family, and participating in social activities.
• Allowing intensity and frequency of exercise to affect self-esteem.
• Being unable to find satisfaction in physical accomplishments.
