CorePower Yoga is offering residents and shoppers in the South Loop a way to leave the stress of the workday behind and get a great, detoxifying workout. Located on the roof of the 555 W. Roosevelt building (the most noticeable resident is a Best Buy), CorePower Yoga is practically unnoticeable to the condo inhabitants, mega businesses and passersby on the ground below sans for a small sign announcing the name.

With locations throughout California, Colorado, Minnesota and Oregon, the 6,000-square-foot space with two studios, a retail boutique and locker rooms for men and women is the first in Chicago. The dark, muted tones and dark woods give the place a sophisticated feel, almost like a modern gym, but this warm and comforting spot is no Bally's.

Fans of Forrest and challenging vinyasa classes will love it here. CPY classes are a form of hot yoga, with the room getting up to 103 degrees for their hot power fusion classes. That may sound daunting, but from the moment class starts instructors encourage you to find your inner strength and listen to your breath and your body, so you're hardly aware of those around you. Besides the signature classes, all of CPY's offerings are an amazing workout. Try the hot fusion class, hot power and yoga sculpt which combines free weights and traditional hatha poses.

Regardless of which class you're testing out, be sure to bring a change of clothes. After a hot yoga class, you'll appreciate the showers, super clean locker room and basic toiletries like you never have before.

CPY is just getting started in Chicago. The South Loop location will be offering boot camp and following suit with workshops and nutrition counseling. Keep an eye out for the Gold Coast location in 2009.
