About the Commercial 2450 Treadmill: The NordicTrack Commercial 2450 Treadmill is the dedicated runner’s go-to treadmill. This smart treadmill can reach speeds of up to 14 MPH (4:17 minutes-per-mile pace), fast enough that, if you’re up for the challenge, you could run a sub-2-hour marathon. This high-speed capability makes it ideal for interval training. The adjustable 12% incline to -3% decline allows you to train with precision, mimicking the exact gradients you’ll face in your race. This specificity not only builds powerful leg strength and endurance by targeting different muscle groups but also enhances cardiovascular fitness and increases calorie burn through more efficient heart rate elevation. The 24” HD touchscreen pivots and tilts for optimal viewing, whether you’re running or following off-treadmill workouts. The RunFlex™ cushioning is engineered specifically for runners. It offers the perfect balance, ensuring you get maximum energy return with every stride, without sacrificing the support you need. The motor has been engineered for enhanced acoustics and durability, delivering a quiet, smooth performance. During your workout, the AutoBreeze™ fan keeps you cool, and a USB-C port lets you charge your phone while you move. After your workout, this foldable treadmill easily folds and rolls away to save space, perfect for your home gym.
