I have been doing it for a few weeks, i also do hip hop/street dance, eat healthy, have low body fat percentage, and good fitness, i’m also planning on going on a 1-2 month intensive Kickboxing course in thailand
How long do you think it will take me?
Okay, first of all muay thai – which is a different art to kickboxing – does not have a ranking system such as white to black belt. Kickboxing does not have a traditional ranking system either, it is a sport. So I am assuming your club is a relatively modern style which your instructor has added a belt system as an incentive.
But as to the grading system itself, it is the same in any art, the honest answer is almost a lifetime! There is no time period.
A lot of the crappy McDojos out there will put new starters through a grading every couple of months, collecting the fees each time, and in a years or two will have a fully fledged black belt with about as much skill and understanding of their art as a moronic ape.
Sorry if that sounded insulting. But it is true.
A true Dojo will nurture an artist throughout their training, often taking many years at each stage, making sure the students understand each and every aspect of their grade before advancing them.
I myself for example spent roughly a couple years per grade, purely because I wanted to spend as much time as I could learning everything I could at that level and I really enjoyed my training at each stage!! I think the longest I spent on one grade was roughly 5 years, maybe a little less as a Blue belt in Judo, purely because I just enjoyed the training and felt no need to progress up until the point I did. (I now have my 1st Dan in it, plus my other ranks).
Just enjoy your training and forget about rank.
