(HealthDay News) -- Walking is a safe and easy way to get exercise, but you should maintain proper form to prevent injury.

The American Academy of Orthopaedic Surgeons offers these suggestions:

• Swing your arms as you walk.
• Walk with your head up, and make sure your back is straight.
• Keep your abdomen flat.
• Point your toes straight ahead.
• Walk with a long, easy stride that doesn't strain you.
