These rules apply to the type of wrestling done in the United States in College, High School, Junior High, Middle School, and most youth wrestling. This type of wrestling is often referred to as "folkstyle" wrestling. The rules for "freestyle" and "greco-roman" wrestling, as is done in the olympics and internationally, are a little different.
