It involves muscles that rotate and turn the femur, attached to the back of the pelvis, muscles that attach to the pelvis, with opposite muscles on the other side. Also for CB the side muscles and spine ribs to hip connective muscles help with CB. Unilateral contraction of the psoas muscles causes rotation of the torso away from the side of contraction and sidebending toward the side of contraction (as if leaning to one side and looking over ones raised shoulder); abdominals assist that movement. The Quadratus Lumborum is also involved in CB to tilt the upper body.

Femur rotation is a totally different area of movement. The Gluteus Maximus moves the femur back under the hip, the rotators of the femur under the pelvis are Gemellus Superior, Gluteus minims, Quadratus and Piriformus. They create the femur countering movements on one side.
Knowing all this is great, but it really doesn't help much, you still have to know how to move all this in unison and in some ways antagonistically to create CB and CA.
I have had plenty of massage therapists and physic therapists in classes before and many did not know how to create CB and CA on the correct side. They did know where the muscles were and what they were supposed to do.

I know from my experience that CA is hard to get correct, I have been working on it for many years. Two things that helped me this year was to relax more, becauses if you lock out the muscles of your upper back you block CA. The other great tip our coach Walter told us was to turn the little zipper first before the upper zipper of the jacket. This great tip helped for me to remember to also CA with my pelvis. I spent three days on our mountain working with this using the drills for CA in the essentials videos.
