Vinicius Draculino is one of Gracie Barras elite. Elite because he was one of the top competitors in his prime and now has a roster of some of the top Black Belts graduated under him.
Check out this recent video published of him rolling with one hand. This is a super hard drill used by a lot of top schools in BJJ. I actually did this last night as a drill and I sucked! I can’t believe how well Draculino is at it. That takes years of practice and co-ordination on his part.
Check out his new website for more info on him Here and if you can, peep one of his instructional DVDs, they are amazing!
