So you thought your treadmill was cool? Wait till you see the K-Mill: it is an omni-treadmill that lets you push your body in more ways than you could on a regular treadmill. You can not only go forward but also backwards and sideways. You get to burn more calories, push your body harder, and achieve better balance in your body. Not cheap but looks like a fun machine.
