lol look at the dates, havent been to this section of the forum in a while!
for the hips, if you know 8 brocades, the dragon sways tail can have a hip focus.
or standing, do a 'hip opening' movement that turns the body ~45º and make the rotation
medial(medi-speak for towards center) from the hip you're focusing on. so i.e. if you're focusing on your right hip you'll be rotating to the left. keep the shoulders square with the hips. that exercise also works the gua.
another one, stand on one leg, extend the other straight, do both medial and lateral rotations of the entire leg, about the hip (make clockwise & anticlockwise circles with your foot as you do it.)
another good one is there's those smooth surface trainer things that basically give you the ability to do a speed-skating motion, also good for the hips.
and while you're trying to fix it, dont do things like full lotus!
