Introducing the Signature Fitness SF-S2 Sprint Demon, the ultimate motorless curved treadmill for high-intensity workouts. Designed for HIIT training, circuit training, sprints, short distances, and walking or power walking, this treadmill will take your fitness routine to the next level. Lightweight: Unlike traditional motorized treadmills, the SF-S2 Sprint Demon uses ultra-thin and flexible slats to offer cloud absorption, making it extremely lightweight and promoting less stress on joints and more activation of muscles. In fact, it can burn up to 30% more calories than a motorized treadmill! Customizable: With 7 levels of resistance, you can customize your workout according to your fitness goals. Start with low resistance for sprinting, move to medium resistance for walking, or crank up the intensity with high resistance for power walking or running while holding the handrails (which imitates a sled push). Multiple hand grips make it convenient to change hand positions when using the treadmill like a sled push. Portable: The SF-S2 Sprint Demon is also incredibly easy to move thanks to its lightweight nature and mobility wheels on the front of the treadmill, allowing you to move it within your home gym with ease. Trackable: The digital display shows calories burned, heart rate, and speed, allowing you to track your progress and adjust your workout as needed. There’s also a large device holder for cell phones and tablets, so you can stay entertained while you train.
