  • When you work out , the blood flow to your body organs increases as well as heart rate and force of contraction also increases to compensate blood flow need of organs..and that's why veins dilate to drain more blood to the heart..also when you work out ,it releases some hormones known as "catacholamines" which also has effects on heart rate,respiratory rate and blood vessels..

    and you know it's actually good, many girls like veiny arms..

    too bad I don't have that much prominent veins on my biceps :(

    hope that helps ^_^
