From BJJ After Forty:

“Ninjas here’s a great set-up that I have been using for sometime now. I started playing with this “leg weave” from the bottom and have developed a series of solid triangles chokes and other submissions from this position. You will also notice that I use a very different hand / leg position when I finish my triangle chokes. On all my triangle chokes I position my body at a 90 degree angle relative to parter (perpendicular). This allows for a very tight triangle choke because the angle lines you directly up with both carotid arteries. You will also notice that in the first triangle choke on this video I connect my hand over and under my partners back. This connection creates a ton of leverage to finalize the choke. If your arms are shorter and you cannot connect them, you can pull on your partners side and create comparable pressure. Give it a try! I have several submissions from the leg weave and will release them soon.”
