Why don't I have blue veins in my muscles and others have blue veins in their arms?

Hello, for us bodybuilders, we like to burst blood vessels. Some people have big muscles, but they can't burst out because their body fat is high and not obvious. You are right to have strong arm muscles. I believe you should have low body fat. It's actually good to have muscles bursting blood vessels. Look at those bodybuilding champions, their blood vessels are bursting.
