Usage: When running, the clamp is clamped on the clothes. In case of emergency, the magnet is pulled off and the machine stops urgently, which plays a role in safety protection.
In terms of safety, the only thing we need to pay attention to when running on a treadmill indoors is the balance of people. Some people feel dizzy after running off the treadmill. In addition, because the width of the running belt of the current treadmill is roughly 40CM, 45CM and 47CM, even if it is 47CM wide, people should pay great attention to the balance of their bodies when running. If their feet accidentally step out of the running belt, they may fall down because of their unstable center of gravity.
When running outdoors, most people rarely find a stadium to run, but usually run back and forth along the road. When there are many people on the road, there may be safety accidents. In addition, a lot of oxygen needs to be inhaled when running, and the exhaust gas exhausted by outdoor cars is very harmful to human body after inhalation.
