Hi all, I've returned to karate after a 15 year hiatus and I'm struggling with my roundhouse kick. Practice will make it better, but for some reason this kick is really eluding me. Part of the problem is that my leg is heavy and I need to build more muscle and lose some weight. However, part of the problem is that when I studied karate years ago, we hit with the top of the foot, whereas now I need to hit with the ball of my foot. It makes sense why the ball of the foot is more effective. However, there is something about the foot position that is making it difficult for me to do the kick and I don't know why. If I angle my foot to hit with the top, I have good aim and speed and I generally feel balanced. However, if I angle my foot to strike with the ball, I have trouble getting my foot high enough and I am thrown off balance. I feel like this shouldn't make a difference. Is it related to muscle memory? I feel like my muscles shouldn't be at all conditioned anymore due to the long time lapse. Any tips for working on the kick would be welcome. Maybe this is just an instance of doing it again and again until it's right.
