How to explain the classification of physical examination types in gymnasiums

You mean the body fat scale, right? As the name implies, it is to check the fat content in your body. If it is medicine, it will be accurate to the percentage.

According to your body fat half ratio, judge what stage you personally belong to. It is higher than your current weight, such as fat content, so it belongs to obesity type.

If the fat content is low, it belongs to emaciation type. I remember someone told me on the floor that bodybuilders do a lot of exercise before going to the stage to reduce the body fat content. A normal person's body fat should be half and half, but those monsters can be reduced to 8%- 15%.
