I've only been training for about a month or so and am running into some minor problems due to my size. What submissions work best for big guys? I'd like to get a few more in my arsenal that I can work on.
Here is what I have been working on:
From guard:
Kimura
triangle (i can't lock it in but i can get in the right position. i think this is a flexibility issue.)
From top:
Americana
Arm triangle
