The Cubii GO is one of my favorite seated exercise machines. It fits under a desk and gets the blood flowing in your body. The Cubii GO Aqua is the upgraded version. It has 10 resistance levels for you to choose from. It comes with a long telescoping handle and built-in wheels, so you can easily move it around.
The Cubii Go Aqua has a ZeroGravitii Flywheel for quiet, smooth operation. It has max weight recommendation of 300lbs. It weighs only 21.8lbs.
