Wing Chun is a Martial Art developed in China which emphasizes on maintaining the balance of the center of mass of our body while we deliver our attacks and defend from opponent's attacks. Sifu demonstrates how one can ground (her)himself by leveraging the center of mass of one's body. The same principle is applied while one attacks the opponent by making him(her) off balance.
Understand and apply the principles from this video and apply them in your Marts Arts learning process.
