This Exercise Ball from Live Infinitely is perfect for working your core. You can use it for Pilates, Yoga, or in place of a chair to really work your core. It comes in a variety of sizes including 55cm,65cm,75cm, and 85cm so you can pick based on your height. It comes in gray or purple. It is anti-burst tested.
I've used my exercise ball while sitting instead of a chair. It helps work my core and gives me better posture. I've also used it for various exercises. This one feels very durable and well made. It comes with a hand pump which made it quick and easy to blow up. It also comes with an extra air plug and a valve remover tool.
You can find this Forever Flex Exercise Ball on Amazon.
