Yes I know it differs from individual to individual, however in what range of BF% does one need to be able to see vascularity in the lower abdominal and hip area (for males)?
Below 7%BF would be a good estimate, but also remember that people hold weight differently. So someone at say, 6%BF might see these veins in the lower abs, another may not. Depends mostly on genetics though, so don't stress too much on it...
