Introduction:

Fitness balls, also known as exercise balls or stability balls, are an excellent addition to any workout routine. These versatile pieces of equipment can be used for strength training, balance improvement, and physical therapy exercises. One crucial aspect of using a fitness ball is ensuring that it’s properly sized and inflated. This article will cover three methods to measure a fitness ball accurately.

1. Diameter Measurement:

The most common way to measure a fitness ball is by determining its diameter; this usually corresponds to the ball’s size. To do this, follow these steps:

a. First, deflate the ball completely.

b. Then, measure the distance from one end of the deflated ball to the other end using a tape measure.

c. Once you have this measurement, inflate the ball until it reaches the measured diameter.

Remember that exercise balls typically come in five standard diameters – 45cm, 55cm, 65cm, 75cm, and 85cm – which correspond to various height ranges.

2. Wall Squat Test:

This method helps determine if your fitness ball matches your height and provides proper support while using it during wall squats – an essential stability ball exercise.

a. Position the fully inflated fitness ball between your back and a wall while standing with your feet shoulder-width apart.

b. Lower yourself into a squat position until your thighs are parallel to the floor.

c. Check whether your knees align directly above your ankles – this signifies that the fitness ball is the correct size for you.

3. Sitting Test:

Another approach to measuring a fitness ball is by evaluating its effectiveness when you’re seated on it at rest.

a. Sit on an inflated fitness ball with your feet flat on the ground.
