gud 4 u guys! I can only see my veins when I flex really hard to the point that I am near shitting. LOL! Anyway, lemme share my story wid u. B4 I really wanted to look cut and veiny, so I sprinted and stuff. But, I still didn’t have those damn veins in my BIs [no problem with forearms, in fact my leg veins are like tree roots ;-)] so I figured must have to do with muscle contractions. I used closegrip chins (really close like 5-6 inches apart) with maximum TUT, and der ya go man! Instant veins in my BIs in three weeks!
