Windy City Boot Camp, Chicago

When certified trainer Camille Finklea isn't demonstrating practical exercises, she's leading phalanxes of women on fitness forays throughout Lakeview. Like athletes in the off-season, campers lunge across open fields, blast through plateaus while jumping rope, or speed up progress with a time-altering montage. Sessions cycle through a constantly changing roster of exercises to keep muscles confused, and because routines are gender specific, they can focus on workouts specifically designed for women. The non-competitive classes foster a supportive environment, and nutritional advice keeps campers on the straight and narrow between meetings.
