Be Nice to Your Knees

The knee is the largest joint in the body. While it gives you flexibility and stability, the number of moving parts it contains makes it vulnerable to injury.

Arthritis is frequently to blame for knee problems. Years of simple wear and tear also can take a toll. Plus, sudden movements can strain or even tear knee ligaments or tendons.

Give your knees a break with these measures:

• Strengthen leg muscles. Strong quadriceps in the front of your thighs and hamstring muscles along the back are particularly key.
• Walk to warm up, then stretch before any workout.
• Increase the amount you exercise slowly and gradually.
• Maintain a healthy weight, since every step you take places about three times your body weight on your knees.
• Wear well-fitting shoes in good condition.
• Protect knees with appropriate padding while playing sports and during kneeling activities, like gardening.
• Choose low-impact activities like swimming, walking, bicycling and water aerobics.
