In previous posts on youtube, Luimarco boasted that his arms are 18" when warmed up. I call bullshit since his bitch-ass forearms create the illusion that his arms are larger than they really are! In his new video he backs out and comes up with some excuse about how it doesn't matter and that he measures his progress visually. Right... I guess that's one way to run around your 16" arm measurements.
