Sit up straight, and don’t slouch is an often–heard phrase. Yet researchers have recently found that sitting upright may actually strain your back muscles. A correct posture — not too upright, not too sagging — can prevent bones from misaligning, reduce back and muscle strain, decrease stress on ligaments, and keep joints functioning smoothly. Some tips:
Stay limber: Adopt a slightly relaxed position at a 135° angle, giving your spine minimal movement
Play fair: Evenly distribute your weight on both hips; don’t favor one side over the other
Explore angles: When sitting, bend knees at right angles at hip level or slightly elevated
Pivot and spin: Use chairs with casters, so you can turn around completely, instead of from the waist
Seize opportunity: Take any chance you get to stand up and move; walking lets you stretch your limbs while stimulating you mentally.
