Some people have two small circles formed on the lower back, where two bones connect the pelvis. Maybe you have already seen them on your back or in other people.
They can appear in both, man and women. In women they are called Venus holes and in man they are called Apollo holes.
These holes appear only in people who are genetically predisposed and have appropriately sized ligaments in the back. We cannot choose whether we have them or not, because it’s genetics.
They are sign of good circulation and a healthy body. If you already have them, it means that you can easily achieve sexual satisfaction, because good circulation is crucial for a healthy sexual life.
They can’t be created with exercising, because they are in the area of no muscles. However, they can become visible if you eliminate some extra fat.
