For those that don't do Wado Ryu karate, and even for those that do, gyakuzuki no tsukkomi is a strange beast.

Nobody punches like that... people will say. What are we doing, punching midgets in the face?

Personally I think there is a lot more in it.

In Wado Ryu karate we have a range of basic punches that we practice which are related.

My feeling is that we start with Junzuki, then Junzuki no tsukkomi and then that leads to Nagashizuki.

Same with Gyakuzuki, Gyakuzuki no tsukkomi and then Nagashi gyakiuzuki.
