Exercise balls, also called Swiss balls or Stability balls, can be used for strengthening the core muscles, as well as a variety of exercises for arms, shoulders and legs. Or you can even use it as a chair to help improve posture and core strength.

Justsports anti-burst exercise balls are made from durable PVC material to increase strength and safety.
Anti-burst balls will not explode like a balloon, however they can still tear or puncture on sharp objects.

Choosing the right size ball for your height:
Height up to 152cm - 45cm ball
153cm to 172cm height - 55cm ball
173cm to 182cm height - 65cm ball
183cm and taller - 75cm ball
(Note that this is just a guideline, applicable specifically when using the ball for exercise. Some people may prefer to use a bigger or smaller ball.)
