From Lex Fridman’s podcast, Craig Jones talks about training at other gyms as a famous person:

You can’t do it if you, if you’ve reached any level of notoriety, whether it’s in the sport or just as a celebrity. You are better off to just have three, four trusted training partners and train privately. That’s the sad situation. People used to say, oh, you could be such and such, go to any gym.

Nah, those days are over now. Now if you show up and you have any sort of name, they’re coming to kill. Honestly, you’re better off. It’s so much safer.

Training is about trusting. Trust is built from safe rounds. Strangers are scary.
