Here are some helpful steps that you can follow in order to tie a karate belt. First, make sure your belt is not twisted.
Then put the end of the belt through one of the holes in the buckle. Then cross the right side over the left side with about two inches of overlap.
Then use both hands to pull on opposite ends of the belt, stretching it tight. Finally, pull whichever side feels tightest with your dominant hand and gently push against with your other hand until it reaches a point where it will stretch no further.
So this is how to Tie a Karate Belt.
