I went to the seminar taught by Leo Vieira on Saturday 5th June 2010 at the Combat Sports academy, Rochester, Kent.
He taught half the seminar with the gi and the other half without. He demonstrated why he was rated by Graciemag as one of the top 3 grapplers in the world with his fantastic understanding of BJJ coupled with his world class ability to convey the skill to mere mortals like me!!
The seminar was well attended - 6 Black Belts including yours truly with only one being non-Brazilian, also yours truly hehehehehe!!
We had a private session the next day but i'm keeping that to myself ;)
