Who ever questioned the reward of makiwara training should be invited to watch the following video by Ippei Kamae. Ippei is a makiwara enthusiast and trains regularly on it. This constant training has given him huge punching power combined with tough nucles.
As a result, he to break wooden board poses no challenge for him. To test his strength he accepted the challenge in the Aoyama Karate Club to break two thick wooden boards during training a few weeks ago. The thickness was judged by his cat, named Oss.
As you can see in the video, Ippei has no difficulties to break the two boards. After a brief preparation and positioning, he goes strait to the punch. Two karateka had to hold the boards so that he could break them. He punched from a very relaxed posture with a smooth gyaku-zuki. Without much force the punch hits the target with high efficiency and accuracy. His constant makiwara training has, therefore, resulted in an excellent punching technique and power.
