Found a cool blog with some visual aids breaking down different high level guys and approaches to Brazilian Jiu-Jitsu from over at a new (to me) blog I'm perusing. Click Here.
I'll be flying to Brazil later today. Spending about 11 days there. Hopefully training twice a day as much as I can the whole trip.
I'll be sure to post my observations about training there while hopefully debunking some of my own pre-conceived notions about training abroad.
