Identity Crisis: 15 Names for a Yoga Ball

Identity Crisis: 15 Names for a Yoga Ball

What’s in a name? We call it a yoga ball, but it’s so much more. For a tool as versatile as our favorite giant rubber spheres, it’s only fitting that there are as many as 15 recognized names for them, but how did it all start?

1. The Pezzi Ball

Whatever you call them today, a plastics manufacturer made the OG in 1963, intending it to be used as a toy. It wound up in Switzerland as a tool for patients with neuromuscular issues, where therapists and patients achieved great results.

 2. The Swiss Ball

When American physical therapists saw the benefits of the ball and brought it back to the US, they gave credit to the country where they first saw it in action.

3. Balance ball

Using a yoga ball promotes an enhanced sense of balance as you make small corrections in position to ensure you don’t roll over!

4. Stability ball

Balance and stability go hand in hand, so it’s no surprise this handle made the list. It’s also why so many people have started using yoga balls in addition to their office chairs.

5. Birthing ball

The yoga ball has helped usher thousands of baby yogis into the world, as many moms have started to turn to more natural positions and environments for the births of their children.

6. Body ball

It’s certainly not a football! The yoga ball’s size and intended use are for the health of the entire body, not just one part.


7. Fitness ball

Whether you use the ball for yoga, office furniture, or just a good old fashioned workout, the yoga ball is a great tool to help you stay in shape!

8. Gym ball

For those who opt for a more traditional gym setting, you’ll still often find a yoga ball among the free weights and other essential fitness tools.

9. Gymnastic ball

Not to be confused with the shorter “gym ball,” many gymnasts and tumblers make use of the yoga ball as well.

10. Physioball

One of the two closest links to the ball’s origin, the name physioball is a throwback to the yoga ball’s first days as a physical therapy tool.

11. Therapy ball

The other nod to the yoga ball’s origin. Of course, when you combine the two, you get physiotherapy ball!


12. Pilates ball

We may be yoga nuts over here at Global Groove Life, but we have lots of love and respect for our fellows who opt for Pilates!

13. Sports ball

Many athletic teams have found ways to incorporate the yoga ball into their routines to ensure strong, well-balanced athletes take the field on game day.

14. Swedish ball

Honestly, we did a lot of research on this one, and our conclusion is that this name just happened after enough people mistakenly said “Swedish” instead of “Swiss.” If you’ve heard otherwise, please share your knowledge in the comments!

15. Yoga ball

Our personal favorite, of course! We use the yoga ball in many of our exercises, and we love stepping up our style with Global Groove Life yoga ball covers!

As if the “Who am I “ question wasn’t enough, I sometimes, oftentimes am compelled to truly consider what Global Groove Life is.  Over the years, I’ve examined our motives, especially when folks ask us questions about the GGL “brand”. I’ve never thought of us as a brand, I’ve always thought of us as a team. Our family, volunteers, artisans, loyal patrons; Team GGL.

Ball Covers FAQs

Before you Order your Yoga Ball Cover:
How can I measure my ball?

We urge you to double and triple check the size of your ball before you order! Do NOT trust the ball package.  Measure it, please. It is quite common for folks to not inflate their ball to the specified size and since we often design in small-batches, we don’t want you to miss out on your favorite design due to a time lapse postal delay due to mismeasurements!

45cm, 55cm, 65cm or 75cm is the height of the ball when correctly inflated but this is quite difficult to measure. A more accurate measurement is the circumference;

45cm ball (height); circumference = 56 inches (142.2 cm)

55cm ball (height); circumference = 68 inches (172.7 cm)

65cm ball (height); circumference = 80 inches (203.2 cm)

75cm ball (height); circumference = 92 inches (233.6 cm)

This is the size the ball needs to be for our cover to fit correctly. All of our covers are checked to fit balls of the specifications above.

PLEASE NOTE: Our 55cm ball covers will fit the 52cm balls sold with the classic ball chair. 

After you Receiver your Yoga Ball Cover:
How can I get the best fit?

We now include instructions and a length of cord to make measuring your ball easier. Our covers are tailor-made to fit your ball snugly leaving no loose fabric.

Use the pre-cut string provided with your ball cover.  The string should wrap around the circumference (the middle of the ball) snugly without any extra length for a correct fit.

To double check you have purchased the right size:

Our strings are cut to 68” for a 55cm ball, 80” for a 65cm ball and 92” for a 75cm ball.

PLEASE NOTE: Our 55cm ball covers will fit the 52cm balls sold with some ball chairs. 

Now place the full circular piece of fabric at the top of your ball. This is the end WITHOUT the plug.

Wrap the cover around the ball gathering loose fabric towards the zip and then start closing the zip while continuing to smooth out loose folds of fabric towards the zip. When you get close to closing the zip completely, you may have some room to inflate your ball a little more for the most snug fit possible.­­



What are our covers made of?

All of our covers are 100% cotton and include a heavy weight YKK zip which wraps around 3/4 of the ball. This makes a close fit over a fully inflated ball possible.

Most of our covers are now made with non-stretch cotton but our cover pattern does allow for some give in the fabric. Our stretch cotton covers provide a little more flexibilty for inflation of your ball.

Who makes our covers?

Our covers are made by a co-op that we set up in Chom Thong, northern Thailand. Each ball cover includes a personal producer tag, giving you a short introduction to the face and personality behind the sewing machine : ).
