Style < technique <<<< fitness
Sorry but even if all you guys "studied" martial arts online the big mean bully is still going to trample you at school. If you actually did study in real life you'll still likely get trampled anyways unless you yourself are huge, that's how it works. It doesn't matter if you studied some magical martial art that somehow makes you impervious to, say, a kick between the legs, you'll still get thrashed.
All those rules about "Size doesn't matter" and all that other junk only apply to adults, sadly.
