Ski Muscle of the Week #10: The Semispinalis, Multifidus, and Rotatores

More spaghetti muscles in this group, but they are shorter than those muscles described in Week #9.  Did you have a turkey for the holidays?   Did you cook the turkey neck?   I usually boil it to make the gravy base, then take the meat off for the cats.  If you use the neck meat, then you know that these muscles are very short and thin.   Not surprising--they anchor the vertebrae to the hips or head, and also anchor the vertebrae to each other in small groups, a few vertebrae at a time.
They also flex and extend the trunk in small segments, plus rotate the trunk and neck at the spine.   (Next time you have a raw turkey neck in your hands take a closer look.)   So they help us stand tall when we ski.  But most importantly, they help us rotate our trunk and neck at the spine. They help us turn our head to the left or right to look for traffic on a busy slope without turning our shoulders—or we can activate these muscles to help us keep our shoulders facing down the slope while our feet turn under us.  Therefore, they are essential to that counter-rotation that is the mark of advanced skiers.
How to get them in shape:
Same exercises as mentioned in Ski Muscle of theWeek #9, with one very important addition:
Prone side bends: Lay on your back on the floor.  Move both legs about ten degrees to the right. Press your shoulders in the same direction, so that your body tries to form a crescent to the right, and hold for a few seconds.  Release and repeat on the left.
