(HealthDay News) -- Although exercise should help improve your health, a medical checkup before you start an exercise program can help ensure a safe beginning.

The womenshealth.gov website offers this list of potential risk factors that should be evaluated by a doctor before you start exercising:

• If you are at increased risk of cardiovascular problems, especially if you've had a stroke or heart attack.
• If you're at increased risk of developing or worsening diabetes.
• If you're overweight or obese.
• If you're pregnant.
• If you've recently become injured or have had chronic pain.
