A Martial Art can be referred to as Internal, External or both. This classification or characteristic is defined by what the Martial Art develops and cultivates in the Martial Artist.
If regular practice in the Martial Art develops the physical attributes of the practitioner, such as speed, strength, agility, and stamina, then this Martial Art is referred to as an External Martial Art.
By contrast, with regular practice a Martial Art may improve the mental, intuitive, and Spiritual aspects of the Martial Artist. The Martial Artist may become more sensitive to the flow of their own energy and may be able to overcome brute force and aggression with efficiency and calm. This Martial Art is thus classified as an Internal Martial Art.
