In the past few years, we have encountered several phenomenon of home gym treadmill running boards broken. Generally speaking, the phenomenon of running boards breaking is relatively rare. From my work experience, the breakage of treadmill running board is mainly due to the following reasons.
1. The weight capacity of home gym treadmill is small while runners weigh higher than limit.
The maximum load of the treadmill does not refer to the runner's weight, but his maximum load. We all know that the pressure we generate when running is far greater than the runner's actual weight. When we buy treadmills, many businesses mislead consumers for competition, making consumers mistakenly believe that the maximum load refers to the maximum weight of the runner, causing misleading. Often the load exceeds the load of the treadmill, causing the treadmill to break.
2. Runners don’t maintain the treadmill.
Treadmills need regular maintenance. The same is true of cars. The most basic maintenance is to add treadmill lubricating silicone oil. Treadmill lubricating silicone oil can not only make the treadmill motor run normally, but also increase the toughness of running board and prolong the life of the treadmill.

If you do the above two points, the running board of treadmill will not be broken.
