 A standard side kick is performed by first 'chambering' by raising the kicking leg diagonally across the body, then extending the leg in a linear fashion toward the target, while flexing the abdominals.The two common impact points in sidekicks are the heel or the outer edge of the foot, with the heel is more suited to hard targets such as the ribs, stomach, jaw, temple and chest.When executing a side kick with the heel, the toes should be pulled back so that they only make contact the heel and not with the whole foot as striking with the arch or the ball of the foot can injure the foot or break an ankle.
