your muscles get pumped with blood when working out.

your veins enlarge because It is easier for them to carry blood around
Since you need it fast and the heart usually beats faster

If you had thin veins then your blood pressure woud go through the roof.


yeah its pretty much because after time and use the blood vessels expand from increased blood flow.

Sorry, but this is incorrect.

During exercise, you want to increase the blood flow in your body because of increased cellular oxygen demand.

Expansion (dilation) of blood vessels --> Decreases blood pressure --> Decreases blood flow --> Hypoxia (lack of oxygen)
