Mawashi-Geri, commonly known as the roundhouse kick, is a versatile and powerful kicking technique in martial arts. This move involves a circular motion of the leg, allowing the practitioner to strike with various parts of the foot. The shin is often used for its strength and impact, while the instep can deliver a more controlled strike. The ball of the foot is suitable for speed and precision, and although the toes can be used, it is generally discouraged without extensive conditioning due to the risk of injury.
