dedicated to the discussion of the chinese internal martial arts of xingyiquan, baguazhang, taijiquan, related arts, and anything else best discussed over a bottle of rum
From what I have experienced I think this is a good illustration of alignment and what is often termed "internal".
I am certain there is far more to the training and from my understanding of bajiquan, the da qiang exercises also play a very critical role in this development (I don't know enough about the Chen training to conclude the same).
