How to choose Swiss balls
• One way to choose a ball for your fitness routine is to go by size or height. The taller you are, the larger the ball you should use. If you’re unsure, it’s recommended to go for a larger size and then deflate the ball slightly if it’s too big.
• Height is one important factor, but another issue to consider is weight. Ideally sized Swiss balls will allow you to sit upright, with your weight distributed evenly on the ball.
• For larger sized people, burst resistant balls are extra durable. These are also a good idea if you have pets, because they’re resistant to sharp claws.
