just in case anyone gives a rip.. ive been training in the gi for about 20mo now. i have taken some breaks due to injury (4wks for an elbow injury and ~3mo when i blew my knee out in september). i'm just getting back to the mat and though my knee isn't 100% i have noticed marked improvement now that i'm training on a regular basis again. anyway, during the break another local gym closed and we picked up most of their members. that gym had a strong no gi program, so we now run 2 no gi classes per week. after last night i have now participated in 2 no gi classes. the instructor is a 10th planet guy so there's a lot of weird terminology that i'm being exposed to, but the positions all make sense after we go over them and drill them. here are my impressions.. -no gi seems to be a lot rougher, at least at my gym. most of my training partners are MMA guys (we don't train striking at my gym) and that mindset definitely shows itself. they crank submissions harder and the rolls are really intense. they aren't being jerks, it's just the way it is. i'm not complaining - i just realize that the mindset is different and i need to be prepared when i show up for the no gi class. -i'm learning many details that i haven't had to worry about in the gi. i think this will help my gi game, and i think the lessons learned in the gi help with no gi. grips are important, and without a gi there i'm learning fresh. i have no wrestling experience so this is all new to me. -leg locks are new to me. we train straight ankle locks in the gi, but calf slicers, knee bars, and toe holds are new territory. after a recent knee injury i'm a little paranoid, but i need to learn it eventually anyway. they are powerful tools. luckily the rougher guys still go slow with the leg locks - they know from experience that they might hurt someone badly.. RNCs on the other hand, they bring it hard. -i am much better at no gi than i thought i would be. our higher level guys still tool me, but i have been eating up guys with whom i am evenly matched in the gi. i do very well with lower level guys who can usually beat me in the gi. it's a confidence booster. overall i like it. i still think i like training in the gi more, but no gi adds a new dimension to my game, will help me with my gi training, and offers additional opportunities for training and development.
