There's nothing like the feeling you get after a good, adrenaline-fueled workout -- your endorphins are high, your body is tingling and you feel way better than you did before, even if it was a total pain to motivate.
But while falling in love with a fitness routine can be amazing, falling into a rut can be a drag -- especially if it starts taking a toll on your waistline. Sure, there are tons of incentives to join a new gym at the beginning of each year, but sometimes the holiday-fueled gusto behind your New Year's resolution wears off; other times, you're just over the gym and ready for a change of scenery. Most of the time, it's just that: time. There's not enough of it, and you don't enjoy your current fitness routine enough to make any. So bottom line, it's all about change.
Fortunately, getting out of said rut isn't as hard as it seems. There are a million (OK, 12) great reasons to put down the potato chips, drag your butt off the couch and start getting excited about working muscles you never knew you had.
In DVD, class or downloadable form, these popular new fitness routines take their inspiration from dancing, yoga, boxing, boot camp, even childhood activities. Some are the secrets behind the sculpted bods of celebrities such as Natalie Portman, Hilary Duff, Sofia Vergara and Kelly Ripa. All were created to kick your butt, improve your confidence level and make you a healthier, slimmer person. Trust us, you'll actually want to get up early after trying some of these. Check out what we deemed the 12 coolest ways to sweat off calories -- until the next great workout routines come along.
