Collegiate wrestling (Folkstyle) is the traditional style of wrestling exclusive to the United States. In Collegiate wrestling the objective is to control your opponent in both the standing and partier (down) position. This is the style of wrestling you will see in middle school, high school, and college competition.
Freestyle and Greco Roman styles are both the international styles of wrestling. These styles focus more on the standing position and are considered a more explosive form of wrestling. In all of the above styles, the ultimate goal is to pin your opponent by forcing both shoulder blades to the mat.
