This is a really awkward move that I’m still perfecting. The best advice that I can give is make sure that the yo-yo rolls in between your arms. You’ll also have to curl in your throwhand index finger to make sure that string doesn’t fly off during the roll. It took me a while, but study that video and I promise you’ll get it. It took me quite a few repeat visits over a few week span but I finally just “got it” one day ;D
