The water makes them move erratically. They'll challenge every muscle in your body while testing your concentration. Lose focus and the H2O Ball becomes an untamed monster. You're forced to learn to lift correctly or you won't be able to hold onto it.

And don't worry about dropping it. It won't break and the cushion of air easily absorbs the impact so you won't damage the floor.

H2O Balls are safe and effective way of training every muscle in your body.

H2O Balls come in three sizes:

Small – up to 33lbs
Medium – up to 55lbs
Large – up to 88lbs

Pump included.
