5 new workouts to try in 2015

We've got a fail-proof "theory" for getting in shape in 2015. Orangetheory Fitness opened in Brentwood over the summer and their heart-pumping group fitness classes (a la Barry's Bootcamp) that use circuit training (switching from rowing machines to weights to the treadmill) are gaining a huge following. We think it's because it's never boring. What makes this group class different from the rest is its focus on the heart. And no, we're not talking about mushy lovey-dovey heart stuff here. We're talking about the heartrate monitors you wear throughout the class to track your progress on the big screen (nothing like a little peer pressure and neighborly competition, right?). Tracking your heart rate ensures you're working out efficiently and making it count. Reach personal target heart rate goals and Orangetheory says you'll burn fat for hours after your class. Class packages start at $199 for 10 sessions ($20/class) and they also offer unlimited monthly memberships for those truly committed to getting in shape. Locations are opening soon in Santa Monica, Torrance and West Hollywood.

Unbreakable is a brainchild of several formidable fitness gurus: FOX NFL commentator Jay Glazer (who looks more like an MMA fighter than an anchorman), former Chicago Bears linebacker Brian Urlacher, and Olympic volleyball player Lindsey Berg. The West Hollywood gym (above Pink Taco) caters to pros but mortals are welcome too. It offers high intensity bootcamps and fitness training for those ready to break a sweat. But honestly, that's putting it lightly: this class will kick your ass. When we took a class, there were two former NFL players, two current players and a certain ripped actor who shall remain unnamed. You can only attend a class or training session here, and it's so much of an ass-kicker, the gym has a cryotherapy chamber in the locker room that blasts sub-zero nitrogen coldness at you to aid recovery. Make sure you have guts, balls and maybe a nice friend who can pick you up after class—you  know, just in case you can't walk. In the words of our editor, "it doesn't kill you so much that you don't want to go back." Unlimited private training sessions will run you $2,000 a month, but drop-in boot camp classes are $35. Unlimited classes are $300/month.

Why is this pilates class unlike other pilates classes? Well, because it's a magical marriage of the strength-based qualities of pilates plus intense cardio and muscle endurance, of course. The Studio (MDR) East’s calorie burning fitness class will make muscles that you didn't even know existed quiver in pain (that hurts so good). With bright pink hues, open concept space, floral accents, and aisles of high-tech reformers, the pristine atmosphere—the second studio just a few minutes' drive away from the first in Marina del Rey—is quite a pleasant setting to feel the burn.

Ever get home from a night of dancing and swear that you must have burned more calories on the dance floor than during any given morning's run? Enter Daybreaker, a rave at the crack of dawn. It's a thing around the world, and it's finally in LA. Who says we're not morning people? Come out when the sun rises to this wellness-focused dance party, where you can look forward to a skeeball machine, live art and performance, a brass band and DJs, and a surprisingly intense workout sesh—as well as complimentary breakfast treats and the most potent of all club drugs: coffee. Daybreaker happens about once a month and each party costs about $20. Sign up on their website to receive updates on locations and dates.
