Starting Position: Stand with both feet together or spread a few inches apart (2-3"), and parallel with each other. Pull your shoulder blades down your back and engage your abdominal muscles to stabilize the spine. Bend your knees slightly and keep tension in your inner and outer thigh muscles. This will help control the tendency to shift sideways during the single-leg stand. Movement: Slowly lift one leg 3-6" off the floor; find your balance on the standing leg. Avoid any sideways tilting or swaying in your upper body and try not to move the standing foot. Hold for 10-15 seconds before returning the foot to the floor. Perform an equal number of repetitions with each foot.
