Training Yin Style Bagua is hard for a variety of reasons. One reason is the sheer physical demand. Another is the amount of material that demands attention. A third is the intense mental requirement to get the techniques right. Another still is that all of this creates a nice, sticky web that tends to make training get really, really stagnant sometimes and tends to make progress feel incremental at best and invisible at worst. If you're stuck in one of these stagnant phases of training, what can you do? Go back to something you "already know" and haven't trained in a while.
