Both the full-sized ball and the half ball each offer a lot of great benefits, but determining which type is the best exercise ball for you really depends on how you will be exercising. I would say the traditional full-sized ball is better for basic core training, so if you’re strictly looking to build up the strength in your core muscles (abs, obliques, etc.), then the full size is for you. The constant instability of the ball is much more challenging on the core than the flat-sided half ball. However, if you’re looking for a wider variety of options to train the rest of your muscle groups in addition to your core, then I think the half ball is a much better option. The dual-platform design gives you twice as many options to use the ball in conjunction with strength training, weight lifting, and more advanced workout routines.
You can fight the crowds, lines, and poor customer service at your local sporting goods store. If you want a more civilized way to get your exercise balls you can find the best exercise balls online at quality, trusted vendors.
This guide is about 98% accurate in helping you determine the best exercise ball size for you. With that being said, it is important to note that everyone’s body type is different. Just because two people are both 5’6″ doesn’t necessarily mean they have the same torso length and leg length. The sizing guide above was created by (a reputable medical and fitness website), and takes into account average body sizes as well as variations in torso length and leg length. However, if you know you have considerably longer legs than what is average for your height, you may want to consider going up in size.
As I said in the introduction to this post, there really isn’t much variation between different exercise ball brands. Choosing the best exercise ball comes down to who’s got the best quality and durability, at the most reasonable price. Since most exercise balls are in a similar price range, quality and durability were my top priorities when comparing each exercise ball that I tested.
