Formation of a fist for the purpose of punching is the most basic knowledge taught in the sport of boxing. Fists are taught in martial arts like karate, kung fu, and taekwondo for the process of punching and striking.[4] Fight 100% says "more than 90% of the people actually don't know how to make a fist correctly", and adds that correct formation means the user "won't break [their] hand", "won't strain their wrist", will "be able to launch very powerful punches", and "be able to knock someone out in one punch".[5]
