One of the most important aspects of martial arts that many people overlook is having a proper fight stance. Having a good stance allows you to stay balanced and deliver perfectly executed techniques.
There are many downfalls to not having a balanced and well developed fighting stance. An improper stance makes you become off balanced which can cause you to fall while while performing techniques and leave you open to counter attacks.
Movement in the correct stance is also vital. While moving, it is important to have the correct footwork. Improper footwork can also lead to you becoming off balance while attacking or dodging.
