Buying a Fitness Ball? Here's What to Look For!

You can buy a gym ball in various colors and sizes. It is an excellent tool for a variety of exercises. Just make sure you buy the right ball. The color you choose is entirely dependent on your personal preference. However, the size you choose is an important factor. Finding the right size fitness ball can be calculated in two ways: arm length and body length. If you are going to use the ball as a replacement for a desk chair, we recommend ordering a size smaller. This also depends on the height of your desk.

Arm Length

Ensure your arms are straight by stretching them forward. Your fingers should also be fully extended. Measure the distance from the shoulder to the end of the middle finger. Since the middle finger is the longest finger, it is used for measuring. If the length is 55-65 cm, a 55 cm fitness ball will fit you best.

Body Length

The most common method is measuring your body length. Stand barefoot against a wall as straight as possible. Then measure your height by marking a spot on the wall or placing a book horizontally on your head. The distance from the ground to the mark on the wall is your body length.

Different Names

If you have been searching for a while, you may have come across various names. Fitness ball, yoga ball, Swiss ball, stability ball, or Pezzi ball. This can be confusing, but don't let it confuse you. They are all different names for the same product. The different names are often used to indicate different purposes. At the bottom of this page, you will find tables with the fitness balls from Matchu Sports. In the tables, you can see which ball is most suitable for you based on your arm length or body length, depending on the chosen method.
