Less is definitely more when it comes to the 3G Cardio Lite Runner Treadmill. As with all 3G Cardio Treadmills, each model is carefully designed for a specific type of user and environment, and the Lite Runner is no different. Because not everyone wants to sacrifice an entire room for their treadmill, the 3G Cardio Lite Runner is the perfect size for smaller rooms and offices. Also, the Lite Runner is actually small enough to fold up and roll through a standard doorway without having to disassemble. Built solid like a tank but made small to squeeze into a tight spot, the 3G Cardio Lite Runner is the perfect fit for your lifestyle.
