I tried a Wing Chun class last year, and found the stance very uncomfortable. Turning both knees in so much was quite a bit painful (I do have past knee problems, so that might be part of it), and the manner in which the pelvis was tucked to the point of created a backward slant (rather than leaning forward or keeping a straight line from head to floor) seemed extremely impractical not to mention uncomfortable. Is it beneficial in ways you don't notice at first? What's the reasoning behind it? Other than that, I like the system, and was thinking about giving it a second shot once I can get my knees a bit stronger.
To be more specific about the training, the teacher is of Moy Yat lineage, and he said he's not yet a "sifu" rank (basically he's teaching at a local community center, but is technically under the supervision of one of Moy Yat's disciples). Was told in the stance that the knees should be close enough together to hold one of those fat striking pads between them... but I just can't do that
