PHF1012: The treadmill is outfitted with a heavy-duty weighted flywheel and a sturdy running belt that respond to your walking / jogging speed. The faster you run, the faster the belt spins, letting you reach whatever speed is comfortable for you. At the same time, the treadmill isn't completely low tech, as it offers a single-button electronics display that tracks your speed, distance, time, and calories (includes two AA batteries). And users with small homes or apartments will love the spring-loaded pull pin, which lets you fold up the treadmill, lock it in place, and store it in a closet or garage. The Easy-Up treadmill-which is endorsed by Denise Austin, one of America's premier fitness authorities-comes with a water bottle and a Denise Austin indoor walking video. It also carries a 90-day warranty on parts and a one-year warranty on the frame. -Fold it up, lock it in place and roll it away for storage.
