If you are unstable - anyone on top of you will also be unstable: When you pin someone from top position your stability is heavily influenced by the stability of the person you are on top of. If he is stable, then you’ll be stable on top of him. Once you understand this, you’ll see that one of you goals when being pinned is to make yourself unstable. This is the central insight in many forms of escape from mount. If you can make your body unstable through stance and motion - kipping, bridging, shrimping - your opponent on top will also become unstable and then you can work to complete the escape. WHEN HIS STABILITY IS DEPENDENT ON YOURS - MAKE YOURSELF UNSTABLE. Then the actual escapes will be much easier to complete
