need help pls advice i have no idea where to start
if you don’t know already, learn horizontal all three ways: The regular way everyone learns and the one you probably know, forwards horizontal (look at paul kerbal for help), and then front mount horizontal.
Learn how to do basic things on all of them.
After, learn how to do basic behind the back tricks and modile. Then try throwing a horizontal throw and binding. Just keep practicing that. I you want to do something like Iori Yamaki then you really need to practice getting your hand behind the opposite hip until you can do it with ease.
