performed striking with the shin in a similar manner to the Muay Thai version with most of the power coming from the body pivot. This kick is usually used as a finisher at closer range, targeting anywhere between the ribs and the back of the knee, this kick can also become a knee at close range. Other kicks include a stamping kick (Mook Jong) for very close range and a sweep performed with the heel in a circular fashion.Every kick is both an attack and defence, with legs being used to check incoming kicks or to take the initiative in striking through before a more circular kick can land. Kicks are delivered in one movement directly from the stance without chambering/cocking. Uncommitted techniquesWing Chun techniques are uncommitted. This means that if the technique fails to connect, the practitioner's position or balance is less affected. If the attack fails, the practitioner is able to "flow" easily into a follow-up attack. All Wing Chun techniques permit this. Any punches or kicks can be strung together to form a "chain" of attacks. According to Wing Chun theory, these attacks, in contrast to one big attack, break down the opponent gradually causing internal damage. Chained vertical punches are a common Wing Chun identifier.[citation needed] Trapping skills and sensitivityThe Wing Chun practitioner develops reflexes within the searching of unsecured defenses through use of sensitivity. Training through Chi Sao with a training partner, one practices the trapping of hands. When an opponent is "trapped", he or she becomes immobile.Chinese philosophy:"Greet what arrives, escort what leaves and rush upon loss of contact"- Yip Man[attribution needed] Close rangeWing Chun teaches practitioners to advance quickly and strike at close range. While the Wing Chun forward kick can be considered a long range technique, many Wing Chun practitioners practice "entry techniques"getting past an opponent's kicks and punches to bring him within range of Wing Chun's close range repertoire. This means that theoretically, if the correct techniques are applied, a shorter person with a shorter range can defeat a larger person by getting inside his range and attacking him close to his body. Curriculum Forms and san sikForms are meditative, solitary exercises which develop self-awareness, balance, relaxation and sensitivity. Forms also train the practitioner in the fundamental movement and the correct force generation of Wing Chun.San Sik (translated as Separate Forms) are compact in structure. They can be loosely grouped into three broad categories: 1) focus on building body structure through basic punching, standing, turning, and stepping drills; 2) fundamental arm cycles and changes, firmly ingraining the cardinal tools for interception and adaptation; and 3) sensitivity training and combination techniques.It is from the forms and san sik that all Wing Chun techniques are derived. Depending on lineage, the focus, content and intent of each form can have distinct differences which can therefore have far reaching implications. This also means that there are a few different ideas concerning what constitutes progression in the curriculum from form to form, so only a general description of overlap between different schools of thought is possible here.The most
