The more fit you become the more your veins will pop out--blue blood being how your blood looks deprived of oxygen. Runners with really lean bodies often develop thick veins--if you're not gaining as much muscle as you'd like then the veins will become pretty prominent.

Red blood cells are always red. Since RBCs make up about 40-45% of our blood, the blood is red. Red blood cells are red because they have a protein called hemoglobin which contains iron. Iron likes to bind oxygen. Oxygen combined with iron is red. The more oxygen iron has bound to it, the redder it is.
Why some people may think that blood can be blue is probably because of the color of our veins, which may be visible near the skin's surface. They appear blue because they do not get as much oxygen as the other tissues.

I've seen that in alot of people who work out. its normal. The veins show more when muscles protrude. Our blood really is blue, but when the air touches it, it turns red. i wouldnt worry
