Total Workout: Cardio

Ask any cardio junkie and they'll 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 — especially not when you've got the supa-dupa strains of your own personal rap trainer Akon commanding you to get busy "Right Now (Na Na Na)", or the right-and rowdy sounds of the Prodigy's "Warrior's Dance" to inspire your inner workout trooper. So, go ahead and surf the surging pop wave of Christina Aguilera's "Not Myself Tonight" and pound it with the LLG vs. GLG Radio Mix of Lady Gaga's "Poker Face".

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

There's nothing like hitching a ride on the beat — be it down-and-dirty, like Beatbullyz sinew-stretching "Skills" or bright-and-bouncy, like Wham!'s "I'm Your Man" — and riding it hard 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 the Crazy Cousin remix of Aggro Santos & Kimberly Wyatt's "Candy", or kept it moving for all eight-plus minutes of "Release Me" by Agnes (Cahill Club Mix) 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, out, and breathing heavy — let Deep Cuts help you help yourself, with the organic chemistry of dance-floor scientist DJ Zinc's "138 Trek", the sax-n-stomp of the Dave Clark Five's "Glad All Over", and the rebooted new wave workout of Blondie's "Atomic" as mixed by Diddy. The Farm helps you keep your body in motion with "Groovy Train" while Afro Celt Sound System's "Anatomic" reminds you of all your gorgeous cardio results, and Talking Heads' "Road to Nowhere" proves itself the ideal treadmill anthem — sure, you're a wheel-spinning human hamster, but you feel great.

Oh, cardio, how do we love you? Let us count us 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 for that rush. But most of all, cardio, we love you because you go so groove-for-move perfectly with music. Music like Dizzee Rascal's cardio kickoff "Dirtee Disco (Club Mix)" and Lena's sexy steam engine "Satellite". If all you want is to "Lose Control" with Missy Elliott, that'll work, but challenging yourself feels so much better when funk-soul brother Fatboy Slim is standing by with the big-beat adrenalin pump of "The Rockafeller Skank" and workout goddess Pixie Lott is ready to spritz-up your energy levels with her "Boys and Girls Remix".
