When I was younger I didnt understand why Kyokushin fighters fought the way they did. Why no face punches ( because they would do serious head trauma due to no gloves and power) Not block more? Probably power as blocking kicks with direct head on blocks instead of redirecting/parrying or moving away would weaken arms. Why not head kicks? Because they train vigorously to counter them, as soon as they recognize a high kick they low kick the grounded leg. Why leg kicks? Because its equal to a baseball bat swing. Karate is very powerful. I still think some kicks like say the round kick from Muy Thai is extremely powerful as well, as is the fully trained American boxing jab cross hook. I admire Okinawan Karate and Mas Oyama Kyokushin deeply.
