Have you ever used a Stability Ball (Swiss Ball) as part of your Workout? Most gyms have them nowadays. If you're using one for the first time you might be thinking about which size ball to use and whether the sizes make any difference.
Well, the size does matter and here is why.
If you use the wrong sized Stability Ball for your height, then you're in danger of, firstly, performing your exercises with poor form which can lead to injury. Secondly, your range of motion (e.g. your ability to bend your back over the ball) during the exercise may be impaired which won't allow you to get the most out of each repetition.
So given your height which size Stability Ball should you be using to get the most out the exercise and to avoid injury?
Here are the measurements that will help you choose the right stability ball?
If you are shorter than 5'2" then choose a 45cm ball
If you are between 5'2" and 5'8" then choose a 55cm ball
If you are between 5'9" and 6'2" then choose a 65cm ball
and if your height is 6'3" to 6'9" then choose a 75cm ball
If you're doing complicated exercises with heavy weights on a Stability Ball I'd always recommend that you have a training buddy to help you.
