Roberto Cyborg Abreu has been working on his own version of inverted guard called Tornado Guard since he was a blue belt and running his own BJJ school. His creativity has taken this move from bottom half guard and developed it into a global position even used in todays UFC. We have been working the Tornado Guard in class over the last few months since we picked Cyborg's training methods of Tornado Guard from the BJJ Camp in 2016. This technique works against bigger people but you have to be patient when implementing it into your BJJ game.
Cyborg has a warm up routine that you can try at home or before your BJJ class to lose the joints and hips for jiu jitsu especially before you try playing this inverted guard type of game that Cyborg plays.
