Vein size

This probably sounds very stupid but I see alot of people at the gym that have huge veins on their arms and sometimes legs.
 
Since I have been loosing bodyfat and gaining muscle I have started to notice small veins forming up arms going to my chest, but they are not big at all.
 
Are the size of the veins you have relative to the size of your muscles or are they just like muscles that take time to grow from pumping more and more blood through them.
 
Any tricks on making this happen or is it just loose body fat and gain muscle?
 
Sorry this question sounds so vain....lol......sorry bad joke...

I dunno but since i started lifting more frequently i got viens on the outside of my forearms when i used to have them just on the inside.  I hope they dont get too big.

huge veins =

bodyfat % ya - gaining muscles ya - genetics

i'm 19
incline bench press 160lbs 100reps
incline dumbells curl 100lbs 2 reps
stiff leg deadlift 220lbs 100reps

Hmm genetics is a major factor....but it is natural to assume they would grow at the same time as the muscles.

I'd say genetics is key, I've had pretty big veins all my life, even when I was way out of shape.  Don't know if muscle contributes to it, but they are lot more noticable with lower body fat.

I LOVE LEG DAY!!

i have about one vein in my right forearm that is hardly noticable, the only ones you can see are in my hands

Didn't have many veins when I was a fat a** but, boom lose the weight, new veins every week. 1st on the inside of my forearms, then on the outside, now I have the one from my bicep going across my chest, it makes you feel kinna good, lets you know your doing something right.

thats awesome, yea i would like to have some more to maybe show some progress, the only thing i dont mind having are the stretch marks on my bicep, they also show progress, even though they are ugly

Mine are about as big as a dime......lol jk jk...
 
I noticed mine start popping out a long on my forearms...chicks dig veins...haha...well ok...I showed my fiance' Ronnie Colemans arms on the back on the NO-Xplod and Cellmass tubs...yea she about puked LOL...

If you're going for bigger veins, try using Nitrix or NO-Xplode.  I noticed mine getting bigger after about 2 weeks on both.  I'm getting more vascularity in my muscles too.  But like everybody else says; genetics, body fat, and muscle size all play a role.

Well...over the past few days I', starting to see vein sign.....got alot comming out on the bottom of my forearms, and the cool one (Note im such a dork for saying this) that everyone has on the side is starting to show some blue lines and almost stick out......
 
To get to the true root cause of my concern.....
 
I guess what is bugging me is my wifes veins are showing much more than mine....and that just inst right......especially when she knows it gets me and is like "Ohh look at my veins sticking out, they are so ugly" at the gym....laughs then walks to the next machine...

vein sticking out is about the muscle size aswell, bigger muscles push the veins onto the skin harder, they got no where else to go.
