Wing Chun Curriculum Forms and san sik Forms 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. What's commonly seen are six Wing Chun forms: three empty hand forms, one "wooden dummy" form, and two weapons forms.
