Iron Fist Liniment helps to protect callouses on the hands and feet. Continued practices will make the hands and feet powerful and insensitive to pain and increase the strength of the bones internally. 
 
The herbs in the Iron Fist Liniment formula are absorbed deep into the skin to help protect it from the jarring force produced by hard breaking techniques.
 
Iron Fist Liniment is for external conditioning needed for improved hard breaking techniques, as are used in Kung Fu, Karate, Tae Kwon Do, and mixed martial arts.
