Understanding the Size and Its Importance

Exercise balls come in various sizes, and choosing the right one is crucial.

It’s essential to consider weight limits. I made sure the ball I chose could support my body weight plus any additional pressure from dynamic movements. A ball with a high weight capacity ensured stability and longevity.

Inflation and Maintenance Tips

Inflating the ball properly was key. I used a hand pump and checked that the ball was firm yet had a little give. Overinflating made it too hard, while underinflating reduced stability. I also learned to store the ball away from sharp objects and extreme temperatures to prolong its life.

Versatility and Usage Options

One reason I enjoy the 21 inch ball is its versatility. I use it for core strengthening, stretching, and even as a chair alternative to improve my posture. Its smaller size makes it easy to incorporate into various parts of my routine without hassle.
