Shaolin Buddhist Monks are well known for their discipline in martial arts, chi control, and meditation skills. Their daily regiment requires six hours of body training starting at 4am, followed by another six hours of buddhist scriptures study. Their martial arts mastery is some of the best in the world as they practice everyday to condition their bodies to take a lot of pain.
Shaolin Monks believe that any body part can be made to take extreme force by applying that extreme force every day for hours, for years. This is a kick-ass example of a Shaolin Monk doing a handstand and flip over from two index fingers.
