Today, just a quote from another article. This is important enough to stand here alone. You'll find the article

" Distorting the back, either by crunching the lumbar vertebrae and splaying the rib cage open or by hunching the shoulders forward and tucking the pelvis under, affects every other part of the body. Since the proper placement of the torso is the foundation of any movement, a dancer with a misaligned spine will develop other deadly technique sins. Problems can ripple all the way down to the extremities and upward to the neck and head. The core will be loose, and unable to provide essential support. A pelvis that either tips back or tucks under will limit the range of motion in the hips. Christine Spizzo's students at the North Carolina School of the Arts constantly work on their placement. The one directive I give in class more than any other she says, is tailbone down, navel muscles lifted. She emphasizes that the tailbone lengthens downward without tucking under, and the navel muscles lift upward, not inward. This opposition allows the external rotator muscles to be actively engaged at the top of the thigh. Spizzo uses the expression
the Four T's - no tucking, tipping, tilting or twisting of the pelvis - as a reminder for the students. "
