Servo technology is being used in treadmills to smooth out the ride by automatically adjusting the belt speed and incline based on the user's weight, stride, and speed. This new technology measures the user's impact with each step and makes micro-adjustments to the treadmill using servo motors to reduce vibration and impact on joints. The smoother ride provides a more comfortable experience for users and better mimics what it feels like to run outside on a soft surface.
