I move to the center of the car. Of course this only works if you are already on the car. This is the one that I favor and use. Here you have to be at least three hundred pounds. It is so simple, you just stand by the door and lean in.
Women have their techniques too.
You get yourself a bag so big that it weighs three hundred pounds then apply the refrigerator technique. Here you need to have very large bust. Somehow that bust out front seems to part the crowd at the door like Moses at the Red Sea. Once in the subway car, you try to get a seat or at least a good standing spot. The easiest technique is to be a smelly, crazy, homeless person.
