The makiwara is used by karate practitioners to practice strikes in much the same way as a boxer uses a heavy bag. The makiwara develops one's striking ability by letting them experience resistance to punches, kicks and other strikes. A poor punch will bounce off the makiwara if the body is not in a position to support the energy generated by the strike. It also develops targeting, and focus, which is the ability to penetrate the target (i.e., opponent) to varying degrees of force.
