As in other close quarter sports, such as fencing and boxing, range is also important in Taekwondo. Depending on the opponent, your fighting range will change. The best range for you is the range at which it is easiest for you to both block and attack, your comfort range. Range will constantly change during the course of a fight. Increasing range when attacked may be considered a retreat or it may be a shrewd move to draw the opponent off balance. Strong opponents will follow you no matter how much you retreat, so sometimes it is best to stay within you comfort range and fight to your fullest. Use range changes to draw your opponent into your attack.
Controlling range while sparring helps you avoid being hit and avoid injuries from blocking. It lets you strike the opponent and it may be used to frustrate your opponent. Controlling range also helps you conserve your energy.
