(HealthDay News) -- Exercise can help you live longer and give you a better body. But you can hurt yourself if you overdo it or don't exercise properly.

The Womenshealth.gov website mentions these safe-exercise tips:

• Check with your doctor before you start exercising. Start out with short workout intervals of just five to 10 minutes.
• Protect yourself with safety gear, such as a helmet or sturdy running shoes.
• Warm up before starting each workout.
• Make sure you drink plenty of fluids, even if you aren't thirsty.
• If exercising outdoors, wear sunscreen.
• Stop exercising if you feel dizzy, nausea or pain.
