I wonder if there are any HN-ers actually practicing bjj? Purple belt here
EDIT: If you really want to know it could be put in as a poll. Ask which martial arts (if any) people here participate in.
(I never had an MMA fight, but many of the guys I trained with did, and I helped them prepare.)
Nah, it's the attitude from BJJ that ended up in MMA culture
(Purple belt here, currently training both BJJ [Gracie Academy] and Judo)
In fairness, though, it could just be selection bias since at least in the US BJJ training tends to be fairly expensive, while community boxing gyms are cheap or free.
