The area you use to run, jog, or stroll on a treadmill is called a treadmill belt. It plays a crucial role in the treadmill's operation with the motor, deck, and rollers by producing a steady and fluid motion. It is mostly used for cardio training. The Treadmill Belt requires regular maintenance. The belt is driven by an electric motor and spins from front to back. The user feels as though they are traveling at the same speed as the belt as a result.
