iFit Live Wiring: This NordicTrack is wired for an iFit Live module. The module, which is sold separately for $99, adds significant value. It connects your treadmill to the Internet for interactive workouts and advice. You can download personalized routines, virtually exercise with the famous personal trainer Jillian Michaels, and virtually compete in 5K races with other real treadmill users. Console & Quick-Start Programs: The console’s 6” window is readable from any trainee’s height and displays a constant stream of exercise data. Twenty workouts are included. These have preset speeds, time limits and distance goals and were designed by a certified personal trainer. You can focus on speed, intensity or incline training. Space-Saving: The treadmill folds vertically to save space. Motor: The T 5.7 has a 2.5 CHP DurX motor, which is equivalent to motors rated 2.75 HP. The motor has a 25-year guarantee and is spin-balanced to minimize noise. iPod Audio: This treadmill has a port for iPods and other MP3 players. You’ll also get two built-in speakers that are each 2” tall. Motorized Incline: A 10% incline can be adjusted electronically at any time during workouts. Training at a 10% slope could triple your rate of calorie burn and help you burn stored fat instead of carbs during workouts. Heart Rate Monitors: Stay in the right zone by monitoring your heart rate during workouts. Pulse sensors are built right into the handlebars. Additionally, the T 5.7 is compatible with wireless telemetry. Wireless heart rate chest straps are sold separately. High Weight Capacity: The NordicTrack T 5.7 treadmill can safely accommodate up to 325 pounds.
