How do world class BJJ fighters like Roger Gracie, Kyra , Jacare and Leo Viera crosstrain to learn takedowns? Has Roger always trained BJJ and just picked up wrestling techniques and Judo techniques? WHat about Jacare and Kyra? Have they always trained takedowns, wrestled in HS, wrestled on the side, or Judo on the side? Did they take wrestling or Judo classes along with their busy BJJ schedule??? Answers would be appreciated Thanks
