A form (hyung) is a series of offensive and defensive movements arranged in a predetermined pattern and practiced by the student against imaginary opponents. There are many requirements for advancing in rank in Martial Arts, but how well a student performs his hyungs may determine if he will pass or fail.
While some hyung movements are designed to develop external strength and power, other hyungs were created to help cultivate internal strength "Ki" (pronounced Kee). External strength is developed through proper tensing and relaxing of the muscles, dynamic and rigorous body movement, and by maintaining correct posture and form. Internal strength is amplified within hyungs by means of correct breathing, centralization of power, and by way of intense concentration with a calm mind. But this is not all hyungs have to offer. They combine the internal and external forces to stimulate the timing, speed, and ability of the student to apply the techniques within the hyungs.
Hyungs stress the development of correct basics. Each block, strike, and stance must be without flaw. If correct execution of a technique in a hyung is overlooked, then the student will be off balance, thus greatly reducing the amount of power he can generate. The technique would be, to a great extent, ineffective due to lack of power and focus. Since advanced combinations consist of basic movements, the practitioner must have solid basics.
Basic forms consist of a few blocks and strikes combined with little in the way of footwork. This early integration of basic techniques helps the student develop rhythm, power, and control. As the student progresses through the ranks, the hyungs become increasingly complex. Footwork and body movement intensify until movement becomes more natural and the student's techniques become fluid. It is the coordinated effort of the mind and body, internal and external powers, and reaching for perfection.

If you do a form 1,000 times, you can see the attacker
If you do a form 10,000 times, everyone can see the attacker"
