Nice little video of Kokyu-ho from Aikido Italia. The difficulty for most beginners in performing this technique is that they tend to fight Uke along their strong line. In the video, the sensei focuses on an upwards cut to extract balance and then the use of hips and entering to finish the technique. For beginners he demonstrates slowly how the technique should be performed on the head in order to make the technique a) Work b) Safe.
I cant count the number of times someone has tried to rip my head of attempting this technique, so if you want your Uke’s to love you then pay close attention on how the movement is done.
