not to kick a dead dog here or anything, but that outside calf crank will get you choked out in a smooth second. had a new guy come to my gym, said he'd been training for about 7 months. he rolled with a guy ive been training for 2 weeks, tried it, got choked out. we went over the tech n theres nothing stopping the guy from sitting back n seatbelting or just wrapping your neck up.
