TruHarmony Yoga, Chicago

Praised for their calorie-blasting abilities by Time Out Chicago and BurnThis, TruHarmony's heated yoga classes help students hone strength, flexibility, and endurance. In beginners' yoga, instructors lead newbies through flow sequences, teaching pupils how to link fundamental yoga poses with careful, balance-challenging movements and deep-breathing exercises; pose modifications help beginning yogis or those with especially inflexible spandex. For those who prefer working out at more neutral temperatures, TruHarmony offers an unheated class each week.

For a more intense workout, students can head over to yoga sculpt and boot-camp sweat sessions, which incorporate strength-training, circuit-training, and plyometric exercises into traditional yoga moves to build the endurance and strength needed to wrangle sticky-mat kites into the air. Mornings can begin in the Sunrise Flow class, and yogis can try something new in the Barre/Flow Fusion classes. A new "Kid's Corner" offers childcare during select class times for practicing parents.
