I didnt watch the video before replying. The problem is Marcelo. You cant stop him from doing what he want yo do. LOL so he's bicep control you and you cant get double underhooks, its a fight. You have to fight for that underhook. If you cant it just mean he's better than you. However you can always let go of the lockdown and start playing your other game such as your overhook game, stomp pimp arm, straight into meathook or even rubber guard. Lockdown is great but you have to be flexible with your game.
