Which specific muscles are primary for generating the explosive hip rotation needed for a strong ura-mawashi-geri?

The primary muscles responsible for generating the explosive hip rotation needed for a strong Ura-Mawashi-Geri (spinning back kick), are the Gluteus Maximus, the Gluteus Medius, and the hip rotator cuff muscles (Piriformis, Obturator Internus, Obturator Externus, Gemellus Superior, Gemellus Inferior, and Quadratus Femoris) of the kicking leg, along with the Obliques of the core. The Gluteus Maximus is the largest muscle in the buttocks and is the prime mover for hip extension and external rotation, providing the initial power for the spinning motion. The Gluteus Medius, located on the outer surface of the hip, assists in hip abduction (moving the leg away from the midline) and also contributes to hip rotation, ensuring stability and control during the spinning movement. The deep hip rotator muscles fine-tune the rotation and provide stability to the hip joint. The obliques (internal and external) stabilize the core during the rotation and transfer force between the lower and upper body. The coordinated action of these muscles generates the rotational force necessary to execute a powerful Ura-Mawashi-Geri. The supporting leg's hip abductors (Gluteus Medius and Minimus) and quadratus lumborum also play a role in stabilization during the dynamic movement.
