If you've been following my posts you know I'm new to Bjj and im a big guy. I've been at Bjj for 3 weeks now and I am taking gi class 2 nights a week and no gi once. Last night in no gi we went over the prayer choke (I think that what it was called) and a guillotine type roll choke when the opponent shoots for the legs and a kind of guillotine under hook choke. I'm sorry I forgot proper terms. Anyway for some reason I have trouble getting the chokes locked in tight or getting the right amount of compression or something. My coach helps me but I get it 2 out of 5 times. One guy in class has no neck and he helps me but it's harder on him lol. Am I just being a frustrated newbie? Are my forearms too big? Am I stressing over nothing? Help! Lol
