Review your approach to training
Every senior grade will reach a point when it seems difficult to make improvements. The obvious solution then is to change your approach to training because you cannot expect a different outcome by keep doing the same things. There is no danger of me falling into this trap during 2011, following my coaching sessions with Andre Bertel, who like Shihan Kato, teaches Asai-ha Shotokan-ryu Karate. This varies significantly from the Shotokan generally taught in the UK, it is not sport karate and it is not a hard style that emphasizes kimi. Rather, the student has to go back to basics to understand junansei (softness), effective use of koshi (the hips), and using the arms and legs like whips.
