Challenge your cardio routine with the SF-T7878 Magnetic Training Treadmill by Sunny Health & Fitness. With a weight capacity of 300lbs, feel confident when you dash on the running surface (47.5L x 17.5W in). Take advantage of the two, 11-pound flywheels that maintain running belt momentum and adds additional resistance to your exercise. Quickly control workout intensity by using the manual incline adjustor tool, which allows you to switch between three fixed levels of incline. Grab the slip-resistant multi-grip handrails, which you can use as support during dynamic cardio exercises, including high-intensity interval training. Use this cardio machine to practice controlled movements like sled-like training exercises that target muscles in your shoulders and improve your speed. Want even more resistance? Cycle through 16 levels of adjustable magnetic resistance that makes it progressively harder to maintain your running speed. Grab the convenient hand pulse grips to monitor your heart rate throughout your workout. Track essential workout data such as speed, distance, time, calories burned, and heart rate, on the performance monitor. Fold your treadmill running deck upward to conserve space when not in use. Easily move your treadmill with the included transportation wheels.
