This is a short (3:59) video showing a) fast way to tie your BJJ belt, and b) a much better, new and improved knot that’ll keep your belt on your hips much longer!
I think it’s worth the extra few seconds to tie the knot in version b, in part because it helps forestall the inevitable yardsale that occurs after a few minutes of training (lapels out, gi over your head, belt undone). But also the resultant belt knot looks a lot better!
I learned this knot from a 5th degree Judo guy, but it’s becoming the standard way to tie your belt at more and more BJJ schools.
