In my ongoing series of threads created in an attempt to clarify and explain the language commonly used to describe things in kung fu, I’ve been through “chi” and “jin(g)”.
Next up is the concept of “double weightedness”, a frusturating term not because of obtuseness (like chi) but because everyone seems to have a different definition of it. I will go through the most common definitions I’ve seen here. These are:
The “Sam Wiley” definition: Named so not because it is unique to Sam Wiley but because he writes the longest posts in which this definition is used - according him, “double weightedness” occurs when both of your feet have an equal amount of weight on them - for example 50% on your right foot and 50% on your left. By this definition, its preferable to have more weight on one foot than on another.
The all-or-nothing definition: This one says that -any- weight on more than one foot is bad technique - that it, 100% of your weight should be on one foot, and 0% on the other. I’ve heard mantis stylists use this definition.
The Sun Lu-Tang definition: Inspired by the anecdote of Sun Lu-Tang being able to place his right shoulder and right foot flush with a wall, and lift his left foot off the ground and hold it there. Impossible for the rest of us, Sun Lu-Tang said he could do this because his body only had one center of gravity, not several. The most confusing of all the definitions, in my opinion.
The Jason Tsou definition: Jason Tsou is my sifu, and he defines double-weightedness as quite simply being off balance. In this definition, the upper body can contribute to double-weightedness as well as the feet - for example, if you are punching forward, you must have a “balancing force” going backwards, otherwise you will be off balance and vulnerable.
Do any of these look familiar to you? Is your definition one of these? If you have a new definition, please let us know what it is. Which one is right, do you think, or are they just different concepts entirely despite being known by the same name?
