In the case of self-defense or legal self-defense, mastering some techniques to make the opponent lose balance can effectively protect yourself. The following are several common methods, but it is recommended to learn and practice under the guidance of a professional coach to ensure the accuracy and safety of the movements: 1. **Low posture**: - Lowering the center of gravity and adopting a stable standing posture, such as lunge or horse stance, can increase your own stability and make it easier for the opponent to lose balance when confronting you. 2. **Center of gravity disturbance**: - Make it difficult for the opponent to predict your movements by moving the center of gravity of the body quickly. For example, suddenly leaning to one side or changing direction quickly can disrupt the opponent's balance. 3. **Limb leverage**: - Use the elbow, knee or wrist as a lever to apply appropriate force to force the opponent to lean or retreat. For example, the wrist lock technique can effectively control the opponent's movements. 4. **Push and pull movements**: - Use both hands to push and pull at the same time, one hand pushes the opponent's shoulder or chest, and the other hand pulls the opponent's clothes or arms to disrupt the opponent's balance. 5. **Foot control**: - Cut off the opponent's support point through fast foot movements. For example, taking a step back or sideways can force the opponent to adjust his pace and increase the possibility of imbalance. 6. **Use the environment**: - Make good use of the surrounding environment, such as using walls or obstacles to limit the opponent's movement direction and reduce the space for him to maintain balance. **Notes**: - **Safety first**: When actually applying these techniques, be sure to ensure the safety of yourself and the opponent to avoid causing unnecessary harm. - **Legality**: Understand and abide by the self-defense laws in your area to ensure that you protect yourself within the legal scope. - **Professional training**: It is recommended to participate in formal self-defense or martial arts courses, systematically study and practice under the guidance of professional coaches, and improve your skills and adaptability. Self-defense skills are not just physical confrontation, but more importantly, they enhance your own alertness and ability to respond to emergencies. Through systematic training, you can effectively protect yourself at critical moments.
