Being new to the GKR style I found it interesting that it contained kata's from both Goju ryu and Shotokan.What I am surprised about is the exclusion of Sanchin kata which is the main power source of Goju ryu.I was taught this kata a few years ago from a Goju ryu practioner and its is very good for generating ki and helping to build up the physique.Its also a good way of preparing the body to take blows which can happen by accident in kumite.After a couple of rounds of the kata first thing in the morning I am awake and charged with energy.
Perhaps its the dangers in doing the kata wrong that have led to its exclusion from GKR but it is one of karates treasurers and is worth exploring.If anybody else is practicing this kata I would be interested to hear of their experiences both positive and negative.
