The Attitube uses water motion resistance to build core strength
If you’ve ever tried carrying an aquarium full of water, you’ll know that not only is the stuff heavy, but it’s also difficult to keep from sloshing back and forth. The Attitube, a relatively new fitness training device, takes advantage of those qualities to build core stability. Designed by Canadian former professional wrestler and present-day strength and stability coach Larry Brun, the Attitube is a simply a clear hollow tube with water inside. You use it like you would a barbell or dumbbell, with the motion of the water adding an extra challenge for your core muscles.
