the lower stomach V

What should I train to get the “V” around the lower abs? I see it in some intermediate and nearly all advanced BB. I have the abs, but not much of a V, even though my obliques are pretty ripped.
-on a side note, I’m not really new to t-mag, i just forgot my login name. Whoever said more T increases short-term memory must have remembered the study wrong…
thanks,
adam
