When performing the side kick, should the foot of supporting leg always point away from the direction of the kick? My instructor said that the foot of supporting leg should be perpendicular to the direction of the kick. When kicking like this, I experience pain in my hip joint. However, if I point it opposite of the direction of the kick, I'm perfectly fine. My questions is: which form of the side kick is correct w/regards to foot placement? I will talk to my instructor about this. Thanks!
