The Strongest Karate Kyokushin Documentary

Old documentary about the Kyokushin style of Karate founded by Masutatsu Oyama, a style known for being full-contact, with very intense physical training.
Some well known practitioners and masters are Nicholas Pettas, Andy Hug, Azuma Takashi, Kenji Midori, Lechi Kurbanov, Judd Reid, Francisco Filho, MMA fighters like Georges St-Pierre, and celebrities like Dolph Lundgren, Michael Jai White and the late Sir Sean Connery.

A lot of the scenes shown are performed by masters with decades of training and experience so please do not try this.
