blue marks in skin while lifting?

[pretty ricky]

has anyone ever noticed little blue marks under skin while lifting heavy?looks like someone stabbed you with a lead prencil.my training partner and i both noticed these marks on each other while lifting and wondered what the hell?

Yeah, I get those when I'm on juice. It's veins underneath your skin, not very close to the surface. When I lift, I get those on my shoulders and back. Anywhere where bloodflow is high when lifting.
