Get the results you want whether you're in training or trying to shed a few pounds with the Livestrong LS8.0T folding treadmill. The LS8.0T is equipped with a 2.5-horsepower continuous-duty motor, powerful enough to deliver speeds of 0.5 to 12 miles per hour and an incline range of 0 to 12 percent (in 0.5-percent increments). As a result, you don't have to compromise when working out--a must when training hard. The treadmill is also extremely comfortable thanks to the MaxComfort cushioning system. The system's adjustable cushioning technology allows you to customize your workout with a softer or firmer feel. With more support for each part of your stride, you'll recover quicker between workouts.
