Jiu-Jitsu in my opinion is never going to stop to grow,” said Royler as transcribed by Kelsey Mowatt. “This is going to be forever you know? And that’s because, in my opinion, the little kid, four years old, five years old, they can train in, and 75 years old, 80 years old they can still train in. In MMA it’s kind of a small hit you know? You can say 17, 16, to 35. After that you start getting old and before that you start to be young. That’s why I say Jiu-Jitsu is a big hit for a lot more people.
