Armbar from S Mount 

When you get to mount always work to climb to high mount. All good things come from there. One way to create submission opportunities is to transition to S Mount.
The idea is to squeeze their shoulders together while keeping nearly all of your weight on them. Pay attention to your base so you don’t lose the pin. Finishing the armbar from here is actually pretty intuitive. I prefer finishing with my weight on them rather than falling off.
I see submissions as the natural conclusion to gaining dominant positions (usually pins) and training the details that allow you to keep control. #bjj #grappling #jiujitsu #mount
