Check out Groupon’s guide to good posture to keep backaches at bay.When sitting, the head is centered over the shoulders with its top parallel to the ceiling; the back rests against the back of chair; the feet are flat on the floor with the knees and hips at 90-degree angles; and the spine is upright, lifting the ribs away from the pelvis with every breath. When standing, the chest is high, the shoulders are back and relaxed, and the feet are parallel.

In these positions, no muscle bears more weight than it’s conditioned to handle and no ligament stretches too far. This doesn’t mean that the spine is straight. Three natural curves—one at the base of the neck, one in the mid-back, and one in the lower lumbar region—cushion movement and help bear the weight of the body stably. And although spines take the brunt of the blame for poor posture, they’re really unwitting pawns caught up in something much larger. Surrounding them, muscles act as support wires that hold the vertebrae in place.
