Power A form is a self-defense scenario against imaginary opponents. Therefore, your movements better be effective. Strong kicks, punches and blocks are essential. It's better to have a strong low kick rather than a weak high kick. Don't give up power for flash.
Balance Stumbling during a forms routine is a major error.
Don't think it's impossible to lose your balance, especially if you're throwing advanced techniques. Therefore, demonstrate good balance and show that you are in control during the entire routine. Some basic, traditional forms do not require much speed from strike to strike. However, even in a simple form, show great speed in a single kick or a single punch. In the more advanced forms, showing a quick combination of movements is important.
