The Cubii Jr is a device that lets you excerice while at your desk. It's a mini elliptical machine that you can place under your desk and use while you're sitting down. It's great for keeping active while working long hours, and also works great for using while just sitting on the couch. It's able to connect to your phone via Bluetooth, so you can track your exercises, and compete against friends. The under-desk elliptical machine has 8 different resistance levels, and a built-in screen that displays workout times, calories burned, and more.
