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:
“No self in the mass: the braver being,
The body that could never be wounded,
The life that never would end, no matter
Who died, the being that was an abstraction.”
—Wallace Stevens (1879–1955)
