How to Tie a Jiu‐Jitsu Belt
To tie a jiu-jitsu belt, start by holding it flat against your stomach and wrapping it around yourself so the ends cross at your back. Then, bring both ends back in front of you, and cross the right end over the left end. Next, pass the end that's on top underneath all of the layers, passing it through the bottom so it comes out of the top. Finally, take the same end and pass it through the gap at the front of your belt before bringing it up and looping it through the belt to form a knot.
Hold your belt in both hands and place it flat against your belly. Check that the label of the belt is facing outward away from you. Space the belt evenly between your hipbones and your belly button. Adjust the belt as necessary such that both ends of are a similar length. Pull the belt tight around your body as you cross the sides in the back. With one side of the belt in each hand, create tension as you pull each side of the belt back. Feed each side into the opposite hand so the belt crosses once in the back. Pull both ends of the belt back in front of you. Extend your arms in front of you creating a snug fit in the back. Adjust the belt as needed so that both ends are of equal length. Cross the right-hand belt over the left-hand belt. Readjust your grip so that each hand is holding the side of the belt now in front of it. The side of the belt that was the right side should now be in your left hand. Similarly, what was the left side will now be in your right hand. Feed the side of the belt on top underneath all the layers. Tuck the top overlapping strap of the belt (in your left hand) underneath all the layers of the belt around your waist. Do this so it comes in from the bottom and out of the top. It will now be the closest strap to your body of all the wraps around your waist. Loop the bottom belt in your right hand around the other belt. As you loop, thread the bottom belt through the gap created by the two belts crossing. Take one end in each hand, and pull the sides away from one another tightly to form a knot. You're ready for action! Hold your belt in front of you. Line one end of your belt up with the right-hand side of your Jiu-Jitsu lapel. This will make it so your right hand is at the end of the belt by the lapel, and your left hand is holding a side with much more slack. Face the label side of your belt away from your body. Your Jiu-Jitsu lapel is the bottom corner of your Jiu-Jitsu shirt. It is different than a suit lapel. Loop the long, left-hand side of the belt around your waist twice. Take the free length of the belt, and wrap it around your body two times. Bring the wrapped end back in front of your body. After wrapping, you should be holding the side that wrapped around your body in your left hand and the side that remained at your lapel in your right hand. Tuck the left side underneath all layers of your belt. Coming from the bottom through the top, thread the left side of your belt under the belted layers around your waist. Adjust the belt as necessary so the two loose ends of the belt are roughly around the same length after tucking. You may need to loosen and tweak things. Cross the left side of the belt over the right side of the belt. Double check that you are crossing the higher side of the belt over the lower side of the belt. The left should be highest. Doing this will create a small gap between the two belts. Feed the right side of the belt under and through the gap you’ve created. Taking a side in each hand, pull both ends of the belt tight to create a knot. You're ready to go!
