A common belief in bodybuilding is that a beginner can make progress lifting rocks. This is not to offend the brutally huge strongmen you see on the MET-Rx World’s Strongest Men on ESPN who lift those 350-lb. Atlas Stones but is to emphasize the point that beginners can make progress on just about any program, using just about anything for resistance, even small Flinstone pebbles. But just because beginners can have success with minimal effort and nonspecific workouts, this doesn’t mean that their training protocol will also work for an experienced athlete, or for someone who wants to go even beyond a “slightly visible” 6-Pack!
Genetics is another unchangeable factor that affects your ability to develop a six-pack, says Holly Herrington, a registered dietitian at Northwestern Memorial Hospital's Digestive Health Center in Chicago. "We get things from our families," including our musculature and build, Herrington says. The offspring of volleyball star Gabrielle Reece, who is 6 feet, 3 inches tall and muscularly lean, with well-defined abs, will almost certainly have a different build than someone who is short and stocky, for example. "It doesn't mean you can't strive [for defined abs], but some of it is genetic," Herrington says.

"There's this notion that carbs are bad and that you need crazy amounts of protein to be lean and fit," says Alcantara, who disagrees, and eats just as much carbs as protein, although the ideal ratio varies based on your goals. "Whatever you eat to get the results you want has to be sustainable, otherwise you're going to end up right back where you started with the same habits that got you there."
