I can't stand your fake posing, with which you've contradicted yourself many times.
Don't talk about martial arts like you know it, "3rd dan".
As far as I know it's unfeasible to get a 3rd dan at the age of 15/16, whichever you've decided on this time.
That is, unless you've been training since you could stand.
I'm pretty sure that's more than "basic karate".
I taught my friend's little brother again today, and I have to say a few months without steady training has really taken a toll on my muscles.
My back and legs aare sore now hahaha.
I'm hopefully joining the Taekwondo and Kickboxing club, although from what I've heard the TKD club is quite a bit worse than I am, so I'm not sure if that can really help me.
I'm looking forward to trying to get back into Judo though, and hopefully jujitsu and muay thai, since they are both at the same Dojo near my place.
