My old ball was great and I wanted to essentially get the same size as that, but I wasn’t sure how to tell which size it was (as it may have not even been the recommended size for me originally). My original exercise ball was a Christmas present, so all the hard work in choosing the right size had already been done for me.Īfter a quick cursory google search where I realized about the different sizes, I pretty much went into procrastination mode because I didn’t know which size to buy. I thought it would be a simple process, but did you know that these things come in different sizes? I actually didn’t, until I went to buy one. I was up for purchasing a new exercise ball recently since my existing one suffered an untimely fate (more on that later). Hopefully, this will make the buying process much more simple and you won’t suffer the same purchasing woes as me! My Experience Purchasing a Exercise Ball In this articles, you’ll find out why size matters, and how to choose the right size exercise ball for you. So, you’re in the market for an exercise ball (AKA swiss ball, yoga ball, stability ball, fitness ball, gym ball, balance ball… plus a few other names, but I think this list is already getting too unwieldy, phew!). There are actually a number of different exercise ball sizes that you can get, and getting the right size is important in allowing you to use the ball correctly.
