wushu vs Kung fu.
here we go 
contemporary wushu, that is to say the competition forms that were created in teh 70’s and then recreated again later to conform to the governing bodies ideas about how wu shu should be done in order to compete in a governed and structured format is actually highly athletic and demanding of it’s practitioners.
It requires great flexibility and as well strength and athleticism to be able to perform.
However, it is incorrect in a kinetic energy sense and the alignment of the body is also incorrect in terms that map across to power generation principles assoiciated with traditional or classical “Kung Fu”.
The arms and legs are often hyper extended in wushu, this is a no no in combat styles.
the back is arched on many a wushu performer and the long term benifits that one acquires with trad practice is not available in the modern wu shu curriculum.
the weapons are absolutely useless martially as they have no weight or tenacity to them.
also, in modern wu shu, power generation is not even comparable to that found in classical styles.
so, in my opinion, contemporary wu shu is great for providing general awareness of chinese martial arts, it is seeking to validate itself via san shou which is chinese kickboxing and is practiced by wu shu players as a way of applying skills martially even though the principles and tenets are obviously quite different.
wu shu has it’s place, wu shu is the correct term for “chinese martial arts” but to equate it to classical methods is like comparing the stopping power of a bb gun compared to a colt 45.
wu shu has it’s place, but many practitioners recognize that it does not provide much in the area of martially applicable skill until the players makes the bridge into the traditional principles and concepts that are driving the actual “fighting” arts as opposed to “performing” arts.
wu shu is to kung fu what balet is to boxing. Both require skill, but both have very different application.
Don’t get me totally wrong, I like wu shu, I like to watch it and I think the performers work very hard, but to make it martially usable, the player has to map that information over into the correct body mechanics that are recquired to make it so.
