Hourglass (anatomy)

The hourglass shape in human anatomy refers to the natural narrowing of the waist area between the ribcage and hips, creating a balanced, curvy silhouette. This shape highlights a well-defined waistline that contrasts with the broader shoulders and hips, contributing to a proportionate appearance. It results from the distribution of body fat and muscle, as well as bone structure. The hourglass figure is often associated with fitness and good health, but individual body shapes vary widely and are influenced by genetics and lifestyle.
