Stability balls are inflatable rubber balls that resemble the old “hippity-hoppity” toys we bounced around on as children. The only difference between the two is the stability ball does not have a handle. Stability balls come in different sizes starting from two feet in diameter on up. The purpose of exercising with these balls is to enhance the body’s balance, core strength, and ability to maintain stability.
When exercising on an unstable surface the muscles that provide stability (i.e. rotator cuff, abdominals and low back) become more active. When performing the following exercises be sure to have ample space free of sharp or hard objects in case balance becomes compromised.
