Training notes – Ai hanmi katate dori kokyu ho (kosadori kokyu ho)

In the below video Sensei Andy Hathaway of the London Aikido Club demonstrates and provides key training points for the Aikido exercise Ai hanmi katatedori kokyu ho (also referred to as kosadori kokyu ho). 

Kokyu ho exercises are used in Aikido to assist in developing internal power.  They can also be techniques in themselves (kokyu nage) or form key aspects of other techniques.  At higher levels of practice kokyu ho principles form part of every technique.
