The core posture and core palm methods of Yin Style Bagua, are foundationally one of the most crucial structures for a fluent understanding of the eight animal languages in the system. The muscle group rotations in between transitions of the core posture determines the rest of the methods within the system. The snake core posture resembles a coiling of two arms, forming a two-headed snake. The lower arm is capable of trapping while the upper arm is ready to strike, or the lower arm is ready to strike, while the upper arm is trapping or defending. Both arms constrict inward yet remain taut with outward force. Base training application methods of the Snake System utilize the rotations and extensions of the core posture or guard position. For example the lower guard arm thrust strikes at an opponent, upon bridging, the upper guard arm binds to the opponent's left arm, and then underhooks, the lower guard arm then grasps the opponent's neck and pulls diagonally inward, returning to the core posture, setting up the next strike or attack.
