Makiwara (Striking board / Hitting post)
In Okinawa it was common for the machiwara (as it is called on the island) to be used by males who were not even martial artists. Miyazato Eiichi Sensei relayed stories about his uncle who was well known in Naha as a strong fighter. Although he did not practice Karate, he regularly used the machiwara and chishi in order to make himself strong, advising the young Miyazato Sensei to do the same.
The machiwara is the number one tool for developing punching power, and learning how to link the limbs to the ground. Traditionally bound in straw and rope, modern variations use a leather pad to simulate skin over bone.
The makiwara is the “number one” tool in Okinawa. You cannot do enough with it.
