The law of flexibility is the law of survival. Kenpo is unique in that it adapts to your build, personality and spirit. If you stand 4 feet 10 inches tall, it makes little sense for you to focus on kicking when your greatest strengths may be mobility and quickness.
If you are a 110-pound woman, it makes little sense for you to grapple with a 230- pound assailant. The old kenpo masters showed their wisdom when they proclaimed that in a fight for your life, you should use what you know best and forget about the sanctity of the style. Every practitioner has different attributes that can make him or her effective.
A tall person with long legs may have an advantage with kicking; a short person may have an advantage with his hands; and a heavy person may have an advantage in grappling. The law of flexibility allows them all to develop their own repertoire of techniques from within kenpo.
