Balance-training exercises are easy to do

-- Stand on one foot. You can do this anywhere, anytime. Do it while brushing your teeth. Or waiting around somewhere. The National Institute on Aging recommends that older people hold the pose for up to 10 seconds, and repeat it 10 or 15 times before switching to the other foot and doing the same.

-- Heel-toe walk: Take 20 steps while focusing on a spot ahead of you.

-- Stand, sit or kneel on a half-ball, a piece of exercise equipment with a hard, flat bottom and an air-filled, rounded platform.
