You heart yoga but want to kick it up a notch now that swimsuit and strapless-dress season is here. Challenge yourself with a month of unlimited classes at Indigo Studio. With more than 15 different types of classes incorporating cardio, yoga, and calisthenics, there's truly something for everyone.  The most popular class is Yoga Booty Ballet, an hour-long fusion of yoga, sculpting, and cardio dance designed to work your abs, lift your booty, and burn calories and fat. Owner Jaclyn Jones discovered Yoga Booty Ballet while living in LA and fell so in love with the class and the results that she decided to bring it back to Chicago exclusively at Indigo Studio. "People who get bored easily with their workouts won't get bored with this," Jones says. "There's a great mind-body component, so you feel great when you're done. I want women to feel good and have fun in their bodies."

The spa-like setting includes two studios where 15 instructors teach 40 classes per week, a changing room, and a shower. Try instructor Jessica Ortega's cardio striptease or core ballet classes or Angela Gusman's Yoga Booty Ballet. "Angela's awesome," Jones says. "She's a little funky and does a good job with combining the spiritual with the athletic and aerobic." Clients are welcome to drop in for a single class, purchase packages, or sign up for single- or multiple-month memberships. Just come prepared for the sexiest sweat fest you've ever experienced.
