You may not typically think about strengthening your wrists and ankles, until they start to cause problems. Performing a few preventive moves at your desk can help prevent injury and improve joint function.

Knuckle Knead: Intertwine your fingers and knead your hands together through the palms and finger pads. This increases blood flow to the area.

Wrist Circles: Extend the arms and rotate at the wrist about 10 times in each direction to improve mobility and deter stiffness.

Forearm Stretch: Extend your arms and cross your right wrist over your left. Intertwine the fingers and push the hands downward toward your body and allow them to loop up through the circle made by your upper arms. Attempt to fully extend at the elbows. Hold 20 to 30 seconds and then switch sides.

Ankle Circles: While seated, extend one leg and rotate at the ankle 10 times in each direction. Repeat with the other leg. Also try drawing the alphabet with your toe when your leg is extended. This helps improve blood flow, foot and ankle strength and foot dexterity.
