One thing that always makes me skeptical about schools teaching animals forms is I think they are not properly doing it.
I know people who used to train, and still train the 7 animals of shaolin. They train hard, and I mean hard with iron body training, qigong, hard physical work outs and conditioning to build those needed attributes to properly execute the animal forms of kung fu. Then on top of that you have to abandon all human emotion and all human thought and become the animal.
Tigers never push their prey away, they are constantly clawing them and pulling them in with strong effective techniques.
Monkeys are play but dangerous and once they hurt you they go back to being playful again.
Mantis is emotionless, still and attacks when it needs to destorying what ever comes in first and climbing its way up its opponet.
Leopards are fast and kill their prey fast and effectively usually bitting and clawing the neck. They climb up trees and haul their prey up with them, so larger predators cannot take their game away. Which does happen, in Africa lions have been known to steal leopards prey from them.
Snakes strike with percision at vital areas of the body and inject their venom into their target. Snakes are also arrogant and know how deadly they are. Almost all other wildlife can feel their intentions and will not cross them. Elephants in Africa will not cross spitting cobras because they can feel the offensive intentions of the cobra. The black mamba is feared amongst all wildlife in africa and is also heavily feared by humans.
I could go on and on about animal behaviors, but I don't want to turn this into some short nature channel novel I don't formally train animal boxing but a few of my brothers do, and I happen to know a southern dragon form and practice its techniques in class. I have seen demos put on by schools that claim to teach the animals of shaolin and I see lots of lack of intent in their forms and lots of physical attributes lacking as well. They have no "jing" in their movements and they look to be weak and ineffective. Now, when I watch someone who really knows animal boxing their forms have power and intent of that animal and I know it would hurt if I got hit with that type of technique or strike. I can see and feel it is effective when the right practitioner executes their form.
Just my thoughts...
