Most people at blue belt and above rely heavily on the elbow escape to escape the mount position. The majority only bump so they can make space, get to their side and perform the elbow escape. I used to suck at the bridge until I took my first seminar with Rickson Gracie. Some other details I picked up from Ryron Gracie on how to set it up properly and now it is my go to escape from the mount. The trap and roll puts you on top of the fight.Be on top if you can. Use the hip escape (shrimp crawl/elbow escape) to set up your trap and roll.
