To choose the right aerobic ball requires finding one that is of good quality and is the right size for your frame. Using an aerobic ball that is not very durable can lead to injury, as can using a ball that is too large or too small. Spending time determining the appropriate size and style of ball that's right for you can help you avoid wasting time and money.
Aerobic balls are used for a variety of exercises, and can often have a different name that reflects the particular exercise being performed. For example, a ball used for abdominal and back exercises is often called a stability ball. Other names for an aerobic ball include Swiss ball, physio ball or exercise ball. Although the names are different, the balls are usually made of the same material and come in the same sizes.
Size is an important factor in choosing an aerobic ball. If the ball is too big for you, it can be hard to use as well as unstable, possibly leading to injury. An aerobic ball that is too small can be hard to use because it affects your posture and can lead to poor from, which can result in injury or cramps. An aerobic ball is a good fit if you can sit on top of it when it is fully inflated with your feet flat on the floor; your legs should be bent at a 90° angle.
In addition to size, the second most important factor in choosing the right aerobic ball is quality. If you are going to be using the ball for exercises that involve putting a lot of pressure on the ball, you want the ball to be firm when it is inflated. Most poorly-made balls are flimsy when inflated because they are made of a cheap material, such as plastic. Higher-quality aerobic balls are usually made of polyvinyl chloride (PVC), which is very durable. Aerobic balls made of PVC tend to keep their shape longer than those made of other types of plastic and are less likely to burst.
Although you might find aerobic balls at a thrift store or yard sale, it’s usually better to buy them new. A used aerobic ball is often less expensive, but it is more likely to have holes in it or burst than a new ball. Aerobic balls are available in a variety of places, including sporting goods stores, exercise studios, gyms and online.
