It also reduces the size of the treadmill, making it easy to store somewhere. The T401 also features quiet motors, which run so quietly that the user can even listen to music, or watch TV while at full sprint. This also lets them run at ease, without any loud motor noises to distract them during their work-out. When compared to another treadmill by Horizon, the T701, the T401 has several disadvantages, including a lower number of programs (6 versus 10) and a slower motor (1.75 CHP versus 2.00 CHP).
