All treadmills are not created equal. The NordicTrack x11i Incline Trainer goes from a 6% decline to a 40% incline so you can reduce impact and increase intensity at will. Compatible with iFit technology, you can watch Google Street View of a real-life route and have the treadmill adjust its inline to match the terrain. Even just walking on this powerful machine will get you sweating fast and recruit the hip flexors and other muscle fibers. Get moving on the 22-by-60 tread belt to find the workout that burns for you.
