Xes and the body

ninevirtuesSo, it turns out that your body is elegantly braced and intricately rigged with muscle.
Your spine, for example, has spinal muscles (multifidi, rotatores) that cross between vertebrae-- two or three vertebrae, depending, so that diagonal stabilization occurs at several different angles.
And, in large, your latissimus dorsi (latin for "really big back muscle") and gluteus maximus (needs on translation; for some reason, everybody seems to know that one) on opposite sides work together and reinforce each other to stabilize your trunk... like a big X.
So do your external obliques and hip adductors, on the front.
And finally, if you look at yourself from the side... your abdominals (rectus abdominis, internal and external obliques, and transverse abdominis) and glutes (gluteus maximus, again) cooperate to tilt the top of your pelvis back behind you. Your hip flexors (quads, and some internal pelvic muscles) and low back muscles conspire to tilt the top of your pelvis forward, in the general direction of your nose.
Wow.
