This is not necessarily a problem for standard users but a heavier user can place an extraordinary load on the motor and controller, causing the system to run hot. The motor and/or controller could eventually overheat and fail while you're walking on the treadmill, typically very abruptly and without warning.Mar 15, 2021
How many pounds can a treadmill hold?
Entry level treadmills tend to hold weight up to 200 to 300 pounds while higher end treadmills (including for runners) can hold between 300 to 500 pounds. To ensure safety and equipment durability double check the manufacturer's weight range before use.
What happens if you exceed weight limit on treadmill?
If a person's body weight exceeds the limit, there is a chance that the treadmill might collapse. The running deck cannot sustain the pressure that a body heavier than its carrying capacity puts on it during running. This will cause it to eventually break or collapse under the weight.
