Slowly and cautiously step onto the balance board with one foot, holding on to a wall or sturdy object for balance if necessary. Take your time adjusting your balance until you can stand upright with your other foot lifted off the floor, abs engaged, and arms extended at your sides.
EXHALE: Keeping your balancing leg still, abduct your other leg out to the side. INHALE: Slowly return the leg toward the midline of the body to complete one rep. After one set, switch the balance board placement to the other side to perform another set.
Master the "Single Leg Standing Balance with Isometric Abduction" exercise before trying this. Only lift your leg as high as you can while maintaining balance and control. Try to keep your standing leg straight and your back flat at all times. Do not lock out your knees. Engage your abs and stare at a focal point in front of you to help with balance.
