Which comes first offence or defense?

[BCBUD]

Punching technique and how to move your feet. When you train defense, you always train with the counter so you have to know how to punch and move your feet.
And many defensive moves are the exact same move as throwing a particular punch. The inside slip is the same as throwing a straight right; the outside is the same as throwing a left hook.

Yeah! Making sure that the shoulder touches the chin with the follow through is an excellent defense against the counter.
