Why are these exercise balls more suitable for gym workouts?

The bumps and lines on the surface of the exercise ball offer increased friction on the body and more grip on the floor, thus keeping your moves safer and more stable.

How do I choose the right size for me?

Here’s how to choose the right size: go for M if your height is between 4'5''-5'1'', L for height between 5'1''-5'9'', XL for height between 5'9''-6'3''. If you are between sizes, please size up.

Do these exercise balls come with pumps?

Yes, they do. Size M (55cm) and L (65 cm) exercise balls come with hand pumps, and Size XL (75cm) balls come with foot pumps.

What are included in the exercise ball package?

One exercise ball, 1 pump, 1 measuring tape, 2 plugs, and 1 plug remover.

What does it mean that the exercise ball is ANTI-BURST

''Anti burst'' means when the exercise ball is punctured by any sharp object about the size of 1*4mm while bearing any weight up to 330 lbs, it deflates quite slowly instead of popping suddenly so as to prevent injuries while use.
