Mushin One of the most overlooked aspects of true karate training is daily makiwara practice.
Constant repetition builds power and kime.
Without kime, you do not have effective karate. When I first started training at Takushoku University is was mandatory that we hit the makiwara 50 times per hand. Even though this does not seem like a high number, a senior student would place his hand two inches behind the board and count only the punches that made the board slap into his palm. This practice quickly forced us to fully commit to each punch without thinking about how many repetitions were ahead because only the focused techniques were counted. Master Funakoshi and Master Nakayama both hit the makiwara before and after training.
