What is veiny arms attractive?

Veiny arms are often considered attractive in the fitness and bodybuilding communities. This is because prominent veins in the arms indicate low body fat and increased muscularity. Veiny arms also give a more defined and chiseled appearance to the arms and can add to the overall aesthetically pleasing look of the body. However, it's worth noting that excessive veiny-ness may also be a sign of dehydration or other medical issues that should be addressed by a doctor.
