Mama wants: A tight core! 'Coregeous' DVD delivers wealth of benefits

The first time you meet fitness guru Jill Miller, you feel the energy radiating off her fit and toned frame. Her always full-to-capacity classes at the Equinox clubs across the country are one of the best investments you can make.

Miller uses medical terms in familiar context to explain what you are doing in class, and by the end of a session, you feel smarter, immersed in a great educational experience and certainly more aware of what you're doing with your body at any given moment. She teaches you to respect your spine, health and precious mobility.

Jill Miller's tutelage in the art of pain management and core strength (her coined term "core-so" will work its way into your vocabulary) will readjust how you approach your fitness routine. Miller will have you preaching her Gospel of Proprioception, the body's ability to sense movement within joints and joint position, mastering your body's blind spots, to your Yoga and Pilates instructors who may not be aware and pushing too hard to do the "pose" instead of understanding the inherent dangers of an aggressive workout.

She believes you don't have to beat yourself up to get fit, and her new DVD, 'Coregeous,' is one exercise tutorial that every Yoga, Pilates and fitness trainer should have in their arsenal of continuing education.

It's revelatory, and done in the classic Jill Miller style of taking big, complicated subjects with hard to pronounce words, breaking them down in completely easy to follow instructions.

Equal Parts Sweet And Seductive; Spotlight on Singer-Songwriter Casey K.

It takes Los Angeles singer-songwriter Casey K. two hands to count her music influences: jazz, Motown, musical theater, reggae, Joni Mitchell, Sarah Vaughn, Janis Joplin and more.

She's also been compared to Nora Jones, Fiona Apple, Colbie Caillat and Erykah Badu. But somehow she makes this myriad mix work in "In Tine," her tightly produced new debut album, that showcases her smoky, sexy vocals that are equal parts sweet and seductive.

The video from the record's first single, "Maureen," shot on location in Paris, already is burning a trail on YouTube. The video explores the notion of love at first sight, an imagination running wild, mesmerizing until the very last scene:

Her first club date in support of the record, at Los Angeles nightclub The Mint, elicited this critique from Corey Irwin of Music Connection (the highly regarded music industry publication):

"A true vocal talent, Casey K.'s voice is remarkably dynamic. She has an enviable ability to belt out emotive lyrics, then quickly drop down to quiet, hushed tones for a somber moment in a song.... At the end of the set, the audience rose in unison for a standing ovation. If she can keep performing at this level, Casey K. should get used to them.... A talent like this doesn't stay hidden very long." wrote Irwin

That, my friends, is called hitting it out of the ballpark.

Chris Christie's interview with Brian Williams, top bariatric surgeon lauds Governor

Governor Chris Christie of New Jersey is beloved and reviled for political reasons, but even his biggest detractors admit the take charge style he exhibited during Hurricane Sandy made him a hero to all in the afflicted area.

And now he is a hero to his family, thanks to the medical action the overweight politician took to knock serious weight off his 50 year-old frame.

In an exclusive television interview today, New Jersey Gov. Chris Christie opened up to NBC's Brian Williams about his decision to undergo lap-band weight reduction surgery shortly after his 50th birthday.

Williams' extended interview with Gov. Christie about his political future and the Jersey Shore's recovery in the aftermath of Superstorm Sandy will air this Friday, May 10, on "Rock Center with Brian Williams" (10pm/9C).

BRIAN WILLIAMS LIVE INTRO: The Republican Governor of New Jersey, Chris Christie has undergone lap-band weight reduction surgery. The story broke in this morning's New York Post.. its not known when the Governor was planning to say something himself, but there has been a noticeable reduction in his weight just in recent days.

Today we sat down for an exclusive interview with the Governor alongside the newly re-built boardwalk in Seaside Heights, New Jersey, mostly to talk about the Sandy recovery -- and it turns out Sandy forced a delay in his surgery until President's weekend of this year, when he checked himself into the hospital on a Saturday morning under an assumed name.

CHRIS CHRISTIE: Last fall I was turning 50 and it really was a moment of reflection for me. And so I really just felt like for Mary Pat and for the kids that I needed to take a more-- a more significant step to try to get my weight under control so that I could have a really active next half of my life.

BRIAN WILLIAMS ON TAPE: The Governor sought the advice of Dr. George Fielding at the NYU school of medicine in New York, a pioneer in the field of weight-loss surgery.
