How to choose a good fitness ball?
Ball size determines the effectiveness of a workout. The ball size is represented by the diameter (often in centimeters). You should pick up a ball that fits with your height. To double-check that you have chosen the right one, you should also sit on the ball and feel if it’s OK or too small/too big for you.
Below are some statistics to help you choose the right fitness ball size. This information includes the exercise ball diameter (in cm) and person’s height (in inch):
The right ball makes you sit comfortably like on a chair sitting near a working desk. Your hips and knees should be at a 90-degree angle, and your thighs parallel to the ground.
If you use the ball for yoga or stretching exercises, you have long legs, or you have any back problems, you should choose a larger ball size. The pressure is the second criterion you should notice when buying a fitness ball.
At its maximum diameter, a fitness ball is firm. If you plan to use this ball for yoga and stretching exercises, a solid ball elevates the difficulty of the exercises.
