Strong Fist is Guy's and Lee's characteristic fighting style, the purpose of which is to cause external damage and break bones. Additionally, they have learned to open at least six of the eight chakra gates, allowing them to briefly increase their physical limits in exchange for severe physical damage after the effects have worn off. In fact, the eighth gate is assured to cause death if opened, while the other seven merely cause exponential degrees of physical damage.

Trivia

 * Sasuke and Kakashi do not actually use this style, but rather use a the key elements and a few techniques that were copied with their Sharingan from Rock Lee and Might Guy.
