I like it. I started training forearms directly two weeks ago and today at a barbecue I was seated, relaxed, when I noticed a surprising network of veins bulging out from them, and yesterday for the first time I noticed, also relaxed, on both legs a calf vein running all the way from my inside ankle to behind my knee. There's a myriad of other big veins that pop up during workouts (hammer curls really bring out the ones in my bis) but simmer down afterwards. What I don't like are the veins in my forehead when I work out. Last week during a conversation with my gym manager he was distracted by a "killer" vein running from my hairline to my temple (right side only) and this week suddenly out of nowhere I get a scary-thick vertical one running straight down the center of my forehead when I work out. Since they're literally the only visible lines in my face those two veins I can do without.
