Let's say I wanted to find a place where I can train BJJ at the intensity and with grappler's of a similar caliber and athleticism that one would find for Olympic medalists in wrestling or Judo. In other words, if I was looking for a BJJ training center where someone could train BJJ at the intensity and find athletes as tough and explosive as the Olympic medalists in wrestling or Judo, what training centers in the United States would qualify? If I was going to look in Brazil, what training centers would qualify there?
