The Importance of Choosing the Right Size Stability Ball

· 4 Comments

The best piece of home gym equipment for improving core stability is the stability ball, also called the exercise ball, balance ball or Swiss ball. Stability balls come in a variety of colors and sizes. Generally, certain colors pertain to the particular height of the ball. So, it is important not to make your decision on a exercise ball based on your favorite color but, on the correct size that accommodates your height.

If your stability ball is too small, your core center is not as active as it should be and you will have the tendency to lean forward if lifting weights while sitting on the ball. If you are positioned too high, then you are working at a much more unstable position. This is fine for some that would like more of a challenge but I would not recommend it for beginners or those who are lifting heavy weights. Just imagine rolling off the back of the ball with heavy weight in your hands.

Choosing the right stability ball for your workout is pretty simple. There are usually 3-4 sizes to choose from for heights ranging from 4′ 7′ to 6′ and taller. You can pick the correct size ball by checking the angle of your knees while seated in the middle of the inflated ball.

For example, while sitting on the ball, your hips and knees should be close to parallel with the floor (at a 90 degree angle). If you do not have access to an already inflated stability ball or you are ordering online, you can check your seating position by squatting with your back against a wall and lowering down until your knees are at a 90 degree position. Mark the wall and measure the height that you need.

Here’s a handy chart for you:

Stability Ball Size Chart:

User’s Height Ball Diameter

under 4’10″ 16″ or 42cm
4’11″ – 5’4″ 21″ or 55cm
5’5″ – 5’11′ 25″ or 65cm
6′ and taller 29″ or 75cm

Order the correct size ball and don’t waste money on one that is too big or too small. A good stability ball should pump up firm and not feel flimsy or mushy while sitting on it. These fun exercise balls are made of PVC and are burst resistant. If you are using weights on your ball, it is usually better to use a “slow deflate” ball. These “slow deflate” balls, will slowly deflate in the event of a puncture. SPRI makes excellent balls that accommodate this need.

Stability balls are fun and versatile additions to any workout program. I have found few fitness devices that offer as much deep layer conditioning of your abdominal muscles. The stability ball is not just a fad and I see it as an effective piece of equipment for every fitness enthusiast

Now that you know how to find the perfect ball for your height, get started today with a stabilty ball today and be on your way to feeling better about yourself and your fitness future.
