BJJ black belt and Navy Seal legend Jocko Willink share s his thoughts and Crossfit. Interessingly, he find parralels between the growth of Jiu-Jitsu and Crossfit:

Crossfit deserves the credit to spreading to the general population what is squatting, lifting etc…

The problem is that some Crossfit practitioners believe that their level fitness will be an asset in a match against a Jiu-Jitsu fighter. Tom DeBlass tells the story about his conversation with a Crossfit athlete that trained at his academy:

“I recently spoke to a cop and asked him about training Jiu-Jitsu. His response was alarming.
“Na man, I do crossfit.”, I looked at him and said, “what?, when arresting someone are you trying to do more pull ups than them or detain them?”
Wtf, people are so delusional. How can so many people lie to themselves?
Nothing against crossfit, I respect the strength of the athletes. In fact, one of the best to do it, Jason Khalipa, a Crossfit Games champion is my friend, and yes, Jason trains Jiu-Jitsu. Why? Because Jason understands crossfit has zero to do with self defense.
Once I had a cross fitter come into my Academy super cocky. He complained about doing the basic class and there was rumblings that in the locker room he said his strength would cause me problems. Well, I trained with him the next day, picked him up over my head like an infant, then gently submitted him about 75 times. He went back to crossfit and said Jiu-Jitsu was too g*y for him. Whatever that means. I guess lifting 100 reps in 60 seconds is cooler.”
