I really pity those of you who train with an instructor who does not teach anything about Qi!
The one big difference between Wenhsiuquan and Jeet Kune Do is that Qigong is expressly part of Wenhsiuquan's training regimen.
It goes like this:
Standing in an upright posture (yoi for the karate people), feet flat on the ground, shoulders relaxed, and so forth (Taijiquan people know the drill...) you begin to stretch your neck upwards so that all the vertebrae have a space between one another. This is not done by straining, but rather in a relaxed posture and while breathing slowly.
The next technique was called, very simply, but still aptly, "Lengthening the limbs with the imagination".
Now- Wu Taijiquan's high stances and techniques are not something I would choose to practice, but hey, I love my high kicks! So- after learning this technique I immediately applied it to my splits! Instead of visualising the muscles softer and longer I actually imagined my legs growing longer! Now THAT really does wonders! In no time I ended up a lot more limber and kicking for the skies!
I am still not as flexible as Chloe Bruce, and really also do not want to be. Still- the increased flexibility I have gained is welcome. I really see no point in kicking beyond your own head's height (and in earlier years some fighters would not even bother going beyond their own waist-level) and I would therefore not spend too much time training to do so. If you, however, want to be the next Chloe Bruce (no- I do not mention Jean-Claude van Damme in my posts) then I hope this tip is of at least some help.
Enjoy your training!
