Just out of my own curiosity what ranks do you guys all have? How long have you been training? At what age did you acquire new ranks (mainly blackbelt ranks)? And if you dont mind who have you trained under? I am just curious as to see how my progression matches with other people. So I hold a third Dan black belt certified with Kukkiwon, and I have trained in ITF style but also know the WTF black belt patterns. I started training at the age of 5 and I am currently 17. I achieved the rank of black belt shortly after my 9th birthday and tested for second dan at the age of 11. I then tested for my third Dan when I was 14 and am currently about one year short of testing for fourth dan. I started my training under Master Friello, head of the Taekwondo branch for the AAU. HE was my main instructor till I was about 2nd dan, after that his successor per say took over the school and I currently train under him.
