What is v lines on a guy?

V lines, also known as the V-cut or Adonis belt, are the diagonal lines that run down from the hips toward the groin area, creating a V-shaped appearance. These lines are caused by the convergence of the pelvic muscles, including the obliques and rectus abdominis muscles. They are more pronounced in men who have low body fat and well-defined abdominal muscles. These lines are often considered a desirable physical trait and can be achieved through proper diet, exercise, and bodybuilding. However, genetics also play a role in the shape and appearance of V lines.
