Beyond strength and flexibility, what specific attribute is most critical for maximizing the effectiveness of Yoko Geri?

Beyond strength and flexibility, the most critical attribute for maximizing the effectiveness of Yoko Geri, the side kick, is precise body alignment and hip rotation. While strength is needed to deliver the kick and flexibility is important for achieving proper extension, proper alignment ensures force from the entire body is concentrated in the kick. Yoko Geri involves extending the leg sideways to strike with the blade of the foot. To generate maximum power, the body must be aligned so force generated from the core, hips, and leg is delivered efficiently. This involves rotating the hips so the kicking leg is fully extended and the body is in a straight line. Without proper alignment, the kick loses power. Hip rotation is critical to effectively delivering power. The hips are rotated to create a chamber and generate power. When executed, there is a powerful rotation to drive the heel to the target. An example is if the body is leaning forward. With the alignment is off, power is diminished, and the kick is less effective.
