Body alignment is the optimal placement of the body parts so that the skeletal bones are efficiently used, so the muscles have to do less work for the same effect.
A good posture requires good body alignment.
Famous quotes containing the word body:
“Men hear gladly of the power of blood or race. Every body likes to know that his advantages cannot be attributed to air, soil, sea, or to local wealth, as mines and quarries, nor to laws and traditions, nor to fortune, but to superior brain, as it makes the praise more personal to him.”
—Ralph Waldo Emerson (18031882)
