"""Personally I've found it to be amazing for Ki developement """
It is beyond my understanding of Kiatsu how you find to be ``amazing for Ki development `` ...still ~ what ever floats your boat.
In the 1950s /60s all the early dan grades were taught Kiatsu by both Kenshiro Abbe Sensei and Ken Williams Sensei.
I am pleased to see from Marks comments that Sensei Williams is still teaching Kiatsu..
It is almost a lost art..........
