Side kick is divided into front side kick and back side kick. Front side kick: while the right foot is moving forward, the left leg is bent and raised, and the knee is retracted to the right as far as possible, so that the sole of the foot faces to the left, and the center of gravity falls on the supported right leg, and the left front is visually observed. Then, support the heel to rotate forward, at the same time, the upper body turns right slightly, the left leg is straight, the knees strongly support the buttocks, and kick it to the left front and lower position with the sole or sole as the force point, flush with the knees. Then as soon as the left foot falls forward and the foot is firmly stepped, the right foot moves forward, and the left leg lifts the knee, and then kicks it to the left. The method is the same as the front low kick. As soon as you kick your left foot straight, you will immediately step down the steps and step on the ground, then step back to your knees for a high side kick, and then return to the actual combat posture when you step down the steps. Backside kick: while the left foot is moving forward, lift the right leg, bend the knee forward, and the center of gravity of the left hand of the upper body falls on the support of the left leg. Then, the left heel rotates forward, while the upper body turns left, and the right knee joint is slightly retracted. The left foot continues to rotate forward to 180 degrees, and the right foot is kicked to the left at a lower position, and the height is flush with the knee. Then as soon as the right foot is firmly stepped, the left foot immediately moves forward to the right foot, and then the right foot lifts the knee to the left and kicks it out in a straight line in front of the left side. The method is the same as the front low kick. As soon as the right foot is kicked straight, the right foot is pressed down immediately, then the right knee is lifted in the left step for high side kick, and then the left foot is retracted in the right step to return to the left actual combat posture.
