i've been invited to watch hokama sensei's students warm up. let me repeat, this is only the warm up. that does not look like fun. the exercises are designed to repeatedly punish your hands and feet. building up stronger, larger, more protective deposits around the bones. basically weaponizing even your weakest and smallest extremities. and it hurts even to watch. brutal. >> james: it's bad, it's bad. >> anthony: james pankiewicz, brit and black belt in shorin-ryu karate, moved to okinawa in 2009 to study budo, or "the way of martial arts." he acts as translator for most of the karate sensei on the island.
