BJJ Mount Escape: Upa, Elbow-Knee & Trap-and-Roll Techniques | BJJ App Wiki

Your neck likely hurts because you are pushing your head into the mat to create space, which strains your cervical spine. Instead, focus on driving your hips laterally by creating a strong base with your feet and then arching your back to lift your hips, not your head.

Against a larger opponent, you need to exploit their weight distribution. Focus on creating a tight frame with your arms to prevent them from sinking their weight, then shrimp your hips out to their armpit side, creating a significant angle and severing their connection to your center.

If your bridge is ineffective from side mount, try focusing on a 'technical stand-up' variation. Bring your knees to your chest to create a shield, then simultaneously drive your hips up and pivot on your feet to get back to your knees, creating a powerful upward and backward motion.
