There’s some other magical way to gain GS expertise than to compete
In my opinion, the only way to learn the sport is to do it, and it means competing or coaching someone to compete. The only way to show expertise is to get better or make someone else get better. And by better I mean getting better competition results, not gym results or fuzzy feelings. You can’t suck in the expertise by watching videos, or living in a country with big GS traditions or by claiming to have expertise on the internet. It’s just the sport, and the competitions. No way around it. Check the facts, because the facts are in the results. It’s so easy. The iron doesn’t lie.
