Avoid kicking your foot to the side or directly in front of yourself.
Maintain good posture—do not bend forward at the waist. Keep your supporting heel on the floor and your supporting leg straight—do not bend your knee. Point the toe of your kicking foot from the time it leaves the floor until it returns to the ground. When you execute this high kick series, you will need plenty of space to move. Practice in a gym, empty room, driveway, or yard. [1] X Research source
