What does it really mean when your veins stick out?
I am a small guy that goes to the gym like everyday I used to run and stuff id say I'm very healthy, my heart beats 48-54 times a minute I'm 5'9 about 140 in weight, I have been going to the gym and recently have started to notice a few more veins sticking out here and there. I already had them in my arms but I'm starting to get one on each side of my chest right below my collar bone and I got one on both sides of my lower stomach and today I noticed one sticking out on my top left ab, what does this mean? I've been told several a things,
1. Low body fat
2. Spider veins or whatever
3. Because my muscles are expanding causing my veins to push out a little more
Explain please? Thanks :) (hopefully the last one though)
