It has a 20" by 60" running area, and ensures the user is comfortable while they exercise by giving them plenty of space. The T6 also supports heart rate monitoring, which allows the user to continually check their own heart rate during exercise. It achieves this through built in pulse grips, which allow for constant monitoring of the heart. In addition, the user may choose to use the included Polar chest strap for heart rate monitoring if they prefer it. When compared to another treadmill by Horizon, the T901, the T6 has several advantages, including a more powerful motor (3.0CHP versus 2.25CHP), a steeper incline (0-15% versus 0-12%) and more programs (10 versus 7).
