Performing the: A Step-by-Step Tutorial Roundhouse Kick. Kickboxing
Shift your weight to your front foot and pivot on it, turning your body sideways while you lift your back leg off the ground.
Swing your back leg towards your target, making sure your knee is slightly bent and your foot is flexed so that you're hitting your target with the top of your foot or the lower part of your shin.
As you make contact with your target, your body should be almost sideways, with your hip turned into the kick to add power.
After the kick, quickly retract your leg and return to your initial stance, ready for the next move.
