I also watch my kicking motions to see if I am kicking too soon or too late. Unlike Krasnoo, Chaturantabut watches the video immediately. When you immediately recognize a problem, it makes it easier for your mind and body to relate to the solution. Chaturantabut and Krasnoo both agree that watching video is better than watching yourself in a mirror. When you're spinning and doing acrobatics, it is too easy to lose sight of yourself.
Fighters can benefit from videotape, too.
It has been very helpful for me when preparing for the next contest. I like to be sure I'm doing the things that help me win. The video builds that connection between tendencies. I then tailored my moves to defeat them. For the most part, videotaping is a great way to improve your skills.
