Pretty much every woman on the planet is more than a little obsessed with flattening out the region between her breasts and pelvis—and it ain't easy!
"I did a poll on Facebook asking which area of your body you struggle with most," says Jillian. "And the number one answer was abs."
We're not surprised: Sixty-two percent of you have told Women's Health that your stomach is the spot that makes you most self-conscious.
If you want to learn how to flatten your stomach, the former Biggest Loser drill sergeant—who grew up overweight but now considers her abs her favorite body part—has an awesome workout for you. But be prepared: Scoring a scorching tummy involves more than a few crunches. (In fact, it involves no standard crunches at all; they tend to isolate one muscle group, so Jillian's not a huge fan.) The best abs workouts for women take a 360-degree approach to finally get over the hump and reduce that belly bump. Think you can stomach it?"
