Total Workout: Cardio

Ask any cardio junkie and he or she will tell you the buzz is definitely worth the work. Walking, running, hitting the elliptical — there are so many ways to get the heart soaring and the sweat pouring. Who could ever get bored? Not you, baby — not when you've got the Black Eyed Peas’ "I Gotta Feeling" or Michael Jackson's "The Way You Make Me Feel" making you feel like it’s time to unleash your inner-workout rock star. So, go ahead and surf the surging pop wave and count off with Britney Spears’ "3," or pound it old-school with Technotronic’s "Pump Up the Jam.”

It's the commitment that's good for you — get your adrenaline fix in Next Steps.

There's nothing like hitching a ride on the beat — be it a heart-pumper like Beyoncé's "Crazy In Love" or something more bright and bouncy, like the Cure's "Friday I'm In Love" — and riding it to the ultimate cardio max. It's easy, too, when you've got just the right tunes — by the time you've burned up a few hundred calories to Kat DeLuna's dancehall scorcher "Whine Up" or kept it moving to Rick James’ funktastic street classic "Super Freak," you'll be at that beautiful, super-fit place where your ticker and your own personal soundtrack are thumpin' to matching bpms.

Can't stop now! Stoke your cardio furnace in Deep Cuts.

Sometimes, even the most gung-ho cardio fiend needs a nudge to get up and start breathing heavily. Let our Total Workout: Cardio Deep Cuts help you help yourself, with the organic chemistry of dance-floor scientists the Crystal Method's "Keep Hope Alive," the big-beat adrenaline pump of "The Rockafeller Skank" from funk-soul brother Fatboy Slim, and the call-out to that supafly chick who made all the hip-hop fellas flip, "Roxanne, Roxanne" by UTFO. Björk helps you put your body in motion with "Big Time Sensuality," while Tony Humphries’ THP Remix of Billie Holiday's "But Beautiful" reminds you of all your beautiful cardio results.

Oh, cardio, how do we love you? Let us count the ways. We love you because you incinerate calories and melt away body fat, because you strengthen our hearts and lungs, because you brighten our moods and help us sleep better at night. We love you most of all for the rush you give us. But most of all, cardio, we love you because you go so groove-for-move perfectly with music. Anthems like Lady GaGa's full-flush "Poker Face"; motivators like Beyoncé's "Single Ladies (Put a Ring On It),” which will have strong, independent women out there — and all those who love them — feeling better about themselves. As you “Work It” to Missy Elliott, sweat it out to Michael Sembello's "Maniac,” and “Whip It” good to Devo, know that a new, more beautiful you will soon be in view for all to see.
