What does a "sway back" posture typically look like?

A "sway back" posture is characterized by a specific alignment of the spine and body segments. It typically involves an exaggerated lordosis, where the lower back curve is enhanced, causing the hips to push forward and the upper body to lean back in a way that can appear as if the person is leaning backwards.

This posture can lead to an imbalance, often requiring adjustment of the head and neck to maintain visual alignment with the horizon. The description of a man leaning his upper body back accurately captures this concept, highlighting how the upper body compensates for the forward position of the pelvis. Understanding this posture is crucial for trainers and fitness professionals, as it can affect movement patterns and the risk of injuries.
