On the UG someone was asking about the best seminars you attended. I thought I'd post here as well:
4 seminars stand out, in no particular order:
Ryron Gracie: (at chattanoogajiujitsu.com great explanation of stabilizing and attacking from the mount, passing closed and open guard, etc.
Pedro Valente: outstanding explanation of standing self-defense moves and a very deep speech on the meaning of jiu-jitsu.
Rorion and Rener: outstanding standing self-defense explanations by Rorion, outstanding ground attacks including leglocks and north-south attacks from Rener
Relson Gracie: great self-defense based seminar, much information about defending against strikes and attacking with strikes on the ground, very enthusiastic and eager to help with any question or move.
