Q: HOW CAN I GET A V-CUT??

A: There're a couple areas that people call 'V-cut'. One is the wide upper back tapering to a narrow waistline, creating a 'V' when looked at straight on from the back. Accomplishing this is a combination of wide upper back and slim waist. Wide upper back is built by exercising lats with pullups, pulldowns, and rows of all sorts. Of course, as is the case with any muscle, it'll grow the fastest when you are bulking up and eating a lot to gain weight (slowly!) in parallel with exercising. Narrow waistline requires the opposite -- losing fat from the stomach which will really only happen when you lose weight. to build a really good 'V' in the back will probably require a few cycles of bulk (when you build up muscle) and cut (when you lose weight and fat), but it's certainly very doable.

The other 'v-cut' is what people sometimes call the upper groin/inner hip/lower abs area. Here the definition can only be accomplished by having very low body fat (read the same article as above for that). Genetics also definitely play a role -- some people will naturally have that v-cut be more prominent than others, even with same body fat.
