Equipment Features

CrossRamp® Technology (Type) Automatic
Shock Absorption Description Features Ground Effects® Impact Control System. This technology absorbs shock at the point of impact and provides maximum stability at push-off. Rather than flex like a bow, it employs a collection of individual shock absorbers to provide variable absorption, while adding important lateral stability. The rear of the deck maintains a solid surface that keeps your foot from sinking and makes it easy to push off, maintaining speed and reducing fatigue.
Special Stride Support Integrated Footplant Technology™
Special Stride Support Description Precor Integrated Footplant Technology™ makes the treadmill move the way you do by changing the belt speed to match that of your foot. As your foot slows and accelerates during impact and push-off, our technology senses it and adjusts the belt speed – up to 710 times a second at 19.3 kph (12 mph). The adjustments ensure that you feel a naturally rhythmic stride instead of the shoe and joint discomfort that come with the drag and pull of other treadmills.

Emergency Stop (Text) Magnetic safety clip, when detached, immediately turns off power, bringing treadmill to a gentle stop. Can also be used to prevent unintended use.
