It is a scientific method to measure by self-weight, because people with different weights can't compare their own strength base. A man's body structure can certainly push up his own gravity. If he can't push it, it can only show that he lacks exercise or nutrition and his physical function has deteriorated.
If you are an athlete, it is not enough to put yourself on the bench. In the United States, the requirement for explosive athletes is always 1.5 times the weight of bench press. This is a common law in American sports, so American high school students who join the school team will be asked to practice bench press.

Precautions for novice bench press
Beginners have limited control over barbells when they just practice bench press, and barbells tend to tilt and their bodies sway from side to side. This is because the muscles of pectoralis major, deltoid and triceps brachii feel poor, and the supine posture of practice will also be affected to some extent.
So you can experience the action with the weight of 12- 15RM first. Hold your horses, don't panic, concentrate, deepen your breathing, and reduce the speed and rhythm of your movements. When inhaling, lower your chest, imagine that pectoralis major is stretched and hold your chest to the limit. At the same time, keep your muscles tense and continue to exert your strength so that the bar can only touch your chest.
