Question 1

What is the most important factor when selecting the correct stability ball size for a client?

Accepted Answer

The client's seated hip-to-knee angle

Answer

The correct ball size is determined by ensuring the client's hips and knees form approximately a 90-degree angle when seated on the properly inflated ball.

Question 2

Which stability ball size is generally recommended for clients who are 5'1" to 5'7" in height?

Accepted Answer

55 cm

Answer

A 55 cm ball is the standard recommendation for clients between 5'1" and 5'7" tall, promoting proper seated posture with 90-degree hip and knee angles.

Question 3

What does an 'anti-burst' or 'slow-deflate' stability ball feature provide?

Accepted Answer

It deflates slowly if punctured rather than bursting suddenly

Answer

Anti-burst (slow-deflate) balls are made of thicker, reinforced material that slowly releases air if punctured, preventing sudden collapse that could injure a client.

Question 4

What is the recommended method to check if a stability ball is properly inflated?

Accepted Answer

Sit on the ball and measure if the thighs are parallel to the floor

Answer

Proper inflation is verified when a standard-height client sits on the ball and their thighs are parallel to the floor, indicating correct height and firmness.

Question 5

How often should a stability ball be inspected for signs of wear, cracks, or damage in a commercial gym setting?

Accepted Answer

Before each class or training session

Answer

In commercial settings, stability balls should be visually inspected before each session to identify cracks, punctures, or deformities that could compromise client safety.
