Found a video that demonstrates a proper traditional/historically authentic martial art. Cannon Fist form from Islamic Long Fist Kung Fu. This style dates back to the 10th Century and was actually used by Muslim warriors during the Crusades (1095-1291C.E.). The style travelled along the Silk Road from China to the Middle East, where its moves were honed on bloody battlefields against Crusaders before returning to China.

A lot of demonstrations of Long Fist these days, including the photo and general description on Wikipedia , aren't authentic Long Fist, but rather the Modern Wushu version, which is effectively created as a form of martial arts based acrobatics (Wushu Long Fist video).
