Outfitted with a hard-working 4.0-horsepower motor and tons of workout programs, the top-of-the-line SportsArt T630 treadmill makes an irresistible addition to any home gym or light commercial facility. The treadmill--which also offers the most powerful lift motor in the industry--is easy on the joints, with a MyFlex deck cushioning system that automatically adapts to the runner's weight. At the same time, the treadmill's spacious 22-by-61-inch belt provides ample running space, so you can jog comfortably on the treadmill without putting undue stress on your knees and ankles. And thanks to the treadmill's dot matrix display, it's easy to monitor your workout progress. The display tracks your calories, distance, time, speed, pace, incline, heart rate, and more on its variety of LED windows.The T630 also includes SportsArt's CardioAdvisor system, the only heart rate system on the market that shows users their high-, low-, and mid-range target heart rates, as well as their actual heart rate during the workout. By accessing this data, you'll see your actual heart rate relative to your training goals, allowing you to maximize your heart rate training. The CardioAdvisor system works throughout any of the T630's multiple workout programs, which include two glute, three interval, one fat burn, three hill, one cardio HR, one weight loss HR, one ZoneTrainer custom HR, and even a fitness test. Other features include a FlowTec cooling and cleaning system and protects the drive motor and key electronics from dirt and heat buildup; a heavy-duty welded steel frame; an ActivZone icon that illustrates which muscle groups are being used throughout the workout; and a 0- to 15-degree incline range.
