  Stability balls, also known as balance balls, have become a very popular piece of home exercise equipment. A stability ball is a large rubber ball that is sturdy enough for an adult to sit on. The idea behind balance ball exercising is simple: By keeping the body off balance, the core muscles must work harder to stay upright. Stability ball exercising is recommended by the American Academy of Orthopaedic Surgeons as a safe and effective way for seniors to exercise at home.
  
  

Wall Supported Squat

• Place the stability ball between your back and a clear, unobstructed wall. Keeping your feet shoulder width apart, bend your knees and allow the balance ball to roll up your back. Stop the squat before your knees pass your toes. Return to an upright position.
  
  

Stability Ball Supported Leg Lifts

• Sit on top of the balance ball so that your hips and knees are bent at 90 degree angles. With feet spread hip width apart, slowly lift one leg so that the knee is almost straight. Hold the leg out for three to five seconds. Slowly return your foot to the floor and repeat with other leg.
  
  

Seated March

• Sit on top of the stability ball with your back straight and your knees and hips bent at 90 degree angles. Slowly lift one leg until the knee gets as close to your chest as possible. Hold for three to five seconds and slowly bring the leg down until your foot is back on the floor. Repeat with the other leg.
