The Corsair FreeRun 100 Curved Treadmill from LifeSpan allows you to experience a more natural style of running in the comfort of your own home. The unique 15-degree curved surface imitates the effect of running or walking on natural terrain. This also gives more of your body a workout, burning up to 30% more calories than standard treadmills. Keep track of your workout data with the easy-to-read backlit LCD display and reach your fitness goals. In addition to high-intensity workouts, the curve is also designed for rehabilitation to improve form and increase posterior muscle activation. The Corsair treadmill does not use an electric motor, but instead uses you as the motor. This cuts down on electricity use and your carbon footprint. It also means that you can control your own pace at will. Enjoy a gentle warm-up, or give it your ultimate effort, the Corsair is designed to keep up with your intensity.
