Exercise ball sizes can have a great effect in your workout because during exercise you are using them in various positions. While smaller balls can improve the effects of certain exercises and larger balls can provide support to your body weight if you have a bad back, choose the right ball depends on your personal height and arm size matters a lot.

In using your height in determining the right exercise ball sizes, the equipment should be level or slightly above the knees. The best and easiest way to measure the right exercise ball is by sitting on it. When doing so, bend your knees at a 90-degrees angle, and your thighs shoud be level with the floor.

Sitting position is the best positition to check if the new ball is for  appropriate height. At an angle of 90-degrees, your hips are level or slightly higher than the knees. When the exercise ball is too small, you might compromise the position of your hips and pelvis when sitting on it. On the other hand, a ball that is too large will not provide opportunities for your feet to touch the ground, putting you in an unstable position. This is exactly why it is very important to get the right ball size to have the right workout.

By calculating the length of your arms from your fingertips to the shoulder, we can also determine the right exercise ball size. Since the length of your leg may vary from that of other people, the arm span can accurately measure the right ball for you.

If the exercise ball will be used for several aerobic exercises and need to hold onto it, the arms cam also provide a better fit for your situaation. However, using this methhod might be a bit tricky (and require more time) as most people usually have more knowledge of their height than their arm span.
