It is very important throughout the form/fundamentals we keep our hip-joints relaxed but level at all times, Do not collapse your hip joints. Often when we are in transition we collapse into the Kwa we are going into rather than maintaining the integrity of level hips and turning cleanly into it.
I've noticed this often when we are going transitioning from ward-off right into roll back we shift our weight rearward collapsing into the left Kwa. When we shift back and forth keep the hips relaxed and level. When we sink there is a tendency to collapse the hip-joint and becoming stuck rather then keeping the two hip-joints level and sinking in sink and evenly with the joints led firstly by the lower body (feet).
When rising there is often a tendency to raise the hip-joints a little faster then the rest of the lower body and disconnect ourselves from the ground, we float. Keep your hip-joints relaxed, level and maintain their integrity at all times. When sitting be mindful of your hip-joints, are they even, are they collapsed?
