The (15 Minute) Belly Blasting Workout

Even women who are otherwise slender and fit can end up with a belly pooch due to underworked lower abdominal muscles. This workout will tap into the deep abdominal muscles—the transverse abdominis—that pull in your waistline like a corset. Do these moves one after another with no rest in between. Then repeat the circuit so you're performing it a total of two times.

7 Facts About Cellulite You Need to Know

How common it is, how it happens... and how to banish it, as well as you can...

Ah, cellulite. Like your nosy aunt, it's annoying—but also a nearly unavoidable part of life. Anybody can develop this pesky skin situation: It appears when collagen fibers that bind fat to the skin stretch and tear, allowing fat cells to expand. Learn more about cellulite and your body, especially how to get rid of those annoying marks once and for all (or at least how to make them less noticeable).

Cellulite Is Not Fat
Don’t get the two confused: Cellulite is just the dimples and bumps that are seen when fat is divided into tiny pockets in the skin, says board certified plastic surgeon Matthew Schulman, M.D. Interesting…

It’s More Common in Women Than in Men
How unfair is this? Women's skin collagen is arranged in parallel rows, like pillars. This pattern lends itself to the compartmentalization of fat, which makes cellulite visible, says Schulman. Men's collagen, however, is arranged in an X-pattern. This creates only very small fat compartments and doesn’t allow for dimpling of the skin.

BodyLove: Ways to Boost Your Confidence

 Weed Your Feed
Scrolling through a newsfeed of size 0 celebrities and models can make you feel like a figure failure. In fact, the more women are exposed to selfies and other online photos, the worse they feel about their appearance, according to a new study. But Facebook doesn't have to mess up your mojo. "The benefit to social media is the ability to curate your own content, so use that power to hide anyone who makes you feel insecure and follow friends and pages that make you feel good," says Claire Mysko, the study author and a project consultant at the National Eating DisordersAssociation. "Creating a feed that includes a variety of shapes reflects the real world and takes you away from the mind-set that there's only one size that's acceptable."

 Like -- No, Love Yourself in Photos

When a friend tags what you deem to be an unflattering pic, resist the urge to cringe. "We're typically much kinder to others than we are to ourselves," says psychologist Robyn Silverman, PhD, author of Good Girls Don't Get Fat. After all, think about how quick you are to like someone else's Facebook photo. Would you be as quick to like your own? Instead of seeking out flaws, ask yourself what your bestie would say about the picture -- maybe that your smile is gorgeous or your legs look toned. "Treating yourself as you would your best friend gets you in the habit of speaking to yourself kindly," Silverman says. "The more you say positive things, the more it becomes a natural part of what your brain thinks."

Dry Skin Remedies for Your Entire Body

It's zero degrees and zero humidity, and suddenly your precious parts have zero tolerance. Help is on the way! We called on winter skin whisperers—top spa pros and dermatologists—to help you ease the dryness and get soft and smooth all over.

 Winter Woe: Chapped Cheeks

Your flaky, flushed face is a telltale sign that you've been braving the elements. "When you're outside for long periods, the cold air extracts moisture from your skin," says Francesca Fusco, M.D., a dermatologist in New York City. The result: cracks in the skin's barrier.

Smooth moves: Because exposure to harsh detergents and even water can strip moisture from your skin, switch to a creamy, sudsless cleanser like Aveda Botanical Kinetics Purifying Creme Cleanser ($21, aveda.com) or a no-rinse formula like Perricone MD Blue Plasma Cleansing Treatment ($39, perriconemd.com). Then slather on a barrier cream, which contains ceramides that fill in the tiny cracks in the skin. Try Avène Hydrance Rich Cream ($30, aveneusa.com). Still flaky? Use a 10-percent-glycolic-acid serum twice a week (after cleansing; before your night cream). We like Renée Rouleau AHA Smoothing Serum 10% ($42, reneerouleau.com). "Acids eliminate dead skin without causing irritation and help repair your barrier," says Renée Rouleau, a celebrity esthetician in Dallas and a FITNESS advisory board member.

Hormones Gone Haywire?

They're your body's secret weapon: Hormones keep your heart thumping, your digestive system churning, and your brain sharp. "Whenever you feel off, your hormones could be the cause," says Scott Isaacs, MD, an endocrinologist at Emory University School of Medicine in Atlanta. They can get out of kilter when you're stressed, tired, or eating poorly and create all kinds of havoc. Here, five signs that your hormones have gone rogue — and how to get them back on track.

You're Tired All the Time

"If you're logging eight hours in the sack and still waking up groggy, low progesterone levels could be stealing your sleep," says Sara Gottfried, MD, the author of The Hormone Cure. Progesterone naturally plummets with menopause, but it can begin dropping as early as your thirties, when your ovaries start releasing fewer eggs. Because the hormone regulates your internal thermostat, a low level of it may cause your body temperature to yo-yo at night, resulting in night sweats that prevent deep, restorative sleep.
