Which stability ball is right for me?

Using the correct size ball helps ensure proper form. For most exercises, determine the correct size ball using the user’s height. The size listed for each ball is its diameter.

User Size: Up to 5'0"
Ball Size: 45 cm

User Size: 5'0" to 5'7"
Ball Size: 55 cm

User Size: 5'7" to 6'2"
Ball Size: 65 cm

User Size: 6'2" to 6'7"
Ball Size: 75 cm

• Regular stability balls have a load limit of 220 lb (user + any weights) and are great for most exercises. Anti-burst balls are thicker and are burst-resistant to loads of 500 to 1,000 lb.
• If punctured, they will not burst; instead, they deflate slowly and safely, protecting the user from potential harm.
• They have a static load limit of 2,200 lb and can handle almost any exercise.

• Periodically check each ball for proper inflation and for any nicks or surface damage that may cause failure during use.
• Always supervise users under 16.
• Keep balls away from excessive heat, abrasion, or anything that might puncture the surface of the ball.
