Which of the following is not a postural defect?

Endomorph is not a postural defect. Endomorph refers to a body type characterized by a soft, rounded physique and a tendency to store excess body fat. On the other hand, flatfoot, kyphosis, and lordosis are all postural defects. Flatfoot is a condition where the arch of the foot collapses and the entire sole of the foot comes into complete or near-complete contact with the ground. Kyphosis is a postural defect characterized by an exaggerated outward curvature of the thoracic region of the vertebral column, giving rise to a rounded upper back. Lordosis, on the other hand, is a postural defect characterized by an exaggerated inward curvature of the lumbar region of the vertebral column, leading to an increased arching of the lower back.
