Yes, though I'd say kickboxing is more of a martial art than just simple boxing like we saw in the video. Kickboxing is more practical than most martial arts though, it teaches you how to actually injure somebody and you don't need to spend a long time learning it to find out how. Training just refines what you already know and makes you more effective at it. I suppose it's a bit of a hybrid. I seem to recall hearing about how if somebody was learning karate, it'd take years before they got to a level where they could use it for self defence effectively, but I don't know how true that is.

It's more than just punching the front of the face and body too, at least the one I learnt was. For example, you learnt how to spin somebody around so you had easy access to the kidneys and the back of the neck too, the move could also send them off balance and crashing to the floor, we were also taught kicks that reached around the back and dealt some damage to the kidneys, too. I recall being restrained at one point or having my arms restrained and having to break free, it was one of the exercises. I think I remember being told once that being taught kickboxing is a good foundation, but when you're in a real fight you'll use anything available to you whether it's knees, elbows, teeth or other objects, like you mentioned.
