I agreee and disagree. The snap side kick in Kenpo is like a jab. This kick should be with the lead leg. I disagree that the kick is chambered. You described it correctly relating it to a boxers jab, but again, a boxed does not chamber their jab. The jab comes from the point of origin from where the lead hand is. The same with the "snap" or jab side kick. The leg comes straight up from the floor and swings out. I may have a different view of chambering than OC does. If by chambering you mean that you bring the kicking foot to the supporting leg knee before you kick as snap kick, that I totally disagree with.
The snap side kick should be done just like it is taught, (maybe I should say how I was taught and how I teach it) in Long 2. You lift the leg straight up from its point of origin from the stance you are in, and the kick hinges out from the knee at that point. You do not chamber the kick to the supporting leg knee before you throw the kick END QUOTE....
On the whole I agree with teej's Idea for teaching and training the side Kick in LF2, before I teach the "kick" I make sure that stance transition from A Neutral to a Horse stance is worked Then introduce the kick.
I am /used to be an OK kicker ( which I brought from my Wado Ryu days) there is a statement which I first heard some 25 years ago in Kenpo, which I had to discard... If you learn to Kick "high" then Kicking "low" will take care of itself.... baloney, there are a different set challenges when kicking effectively below the waist, that's why I like teej's reference to a boxers jab, eliminating chambering, executing the kick and then quickly re-establishing a base.
