The two small indentations found on the lower back, just above the glutes, are commonly known as **Venus dimples** in women and **Apollo dimples** in men. Medically called sacral or lumbosacral dimples, they are a natural part of human anatomy. These dimples appear where the skin is attached to the underlying bone at the **posterior superior iliac spine (PSIS),** creating a permanent indentation.

For many years, people believed these dimples were entirely inherited. While genetics do determine the underlying bone structure and ligament placement, experts now understand that their visibility can also be influenced by body composition. As the article explains, **”the structural foundation is indeed genetic,”** but factors such as body fat percentage and muscle development affect how noticeable the dimples appear.

Because this area naturally stores body fat, the dimples may be less visible in some people and more defined in others. Building strength in the lower back and gluteal muscles can make them stand out more. Exercises that improve muscle tone in the surrounding area not only enhance their appearance but also support better posture, core strength, and spinal stability.

Although many people view Venus and Apollo dimples as attractive physical features, they are simply a normal variation in human anatomy. Their presence or absence is not a measure of health or fitness. Instead, they reflect a combination of genetics and body composition. As research has shown, **”environmental and lifestyle factors play a massive role in their visibility,”** making these dimples an interesting example of how inherited traits and physical fitness can work together to shape appearance.
