The procedure for level 1 of the internaliron palm coconut break, in time and conjunction with the other Panther tapes, will create a well rounded fighter. In authentic Five Elder martial arts of White Tiger, White Eyebrow, Northern Shaolin, Plum Flower and 18 Daoist Palms, two person forms are included with each solo form. Traditionally one had to wait 15 years before learning two person forms. This is a safe way to spar unless you are too slow.
Nothing is subsonscious without repetition.
Anything less than subconscious is too slow. This two person form will teach you how to effecively use your iron palm skill against the different body types of taller and stronger, taller and weaker, shorter and stronger, and shorter and weaker. These were the original forms of sparring in Kung Fu. You will learn to stay in the eye of the hurricane without breaking from the action. By working with differnt body types in differnet terrain, weather and clothing, the finer points of adjustment or range and angle are finely tuned.
