I don't see a stark dividing line between them. I teach both from the very beginning. I teach a simple grip escape (actually, the foundation of both escapes and techniques); a simple, direct block; simple strikes; etc. as first work. In grappling, attack and defense are less obviously divided, since a block is also an attachment to the striking limb and a counter is also the beginning of a takedown. When we're talking specifically about strike vs. strike, it's a toss-up. I teach the block first, but only because I want to teach the strikes as a follow-up to the block. They happen in the same class.I was talking about this with my son today who's a brown belt in kenpo and a green belt in taekwondo. We were talking about what's more important to learn first attack or defence. Now I trained my son for years before he started training at a school with his friends then decided to do taekwondo as well but we're both different types of fighter he's a very co-ordinated fighter can work well on the inside and use footwork and timing well and has great knowledge of his stances. My styles more agressive move in and out and work the counter and pick off with kicks And we have totally different ideas.
He believes that attack should be the first thing that's taught because you need to know how to put someone away as quid as possible but I think defence is most important to learn first since if you can't defend and you get a hard hit and get knocked out your attack is no good.
Just wondering what others think.
