Sonobazuki is the most basic punch there is within Karate. This Japanese writing その場 means Sonoba, which translates into "on the spot". The Kanji 場 itself means place.
Although you can use several different kind of stances for practice, I have chosen to use Naihanchi dachi, which is the standard choice for Wado techniques and internal development.
In this blog I would like to share a trainingmethod with you, which empasises squeezing the elbow. Have a look at the pictures below, where you can see the transition between the punches clearly. Trainingwise, you can actually do the transition, so that you can emphasise squeezing the elbow. I demonstrate this method in the video where I also mention the keypoints.
