Each instructor of Nirvana Yoga has had her falling-in-love moment with yoga. Jessica Fill turned to the ancient art after a shoulder injury stopped her swimming career, Melissa Pilat found yoga a useful complement to her 18 years of ballet and modern dance, and Abra Goldman began practicing yoga to augment the fitness cultivated through her lifetime dedication to running. This band of experts leads fluid classes, drawing from the Baron Baptiste style of flowing from pose to pose in a manner that creates a rigorous, strength-building practice linking movement to breath. The team also teaches Power Vinyasa classes in an 88- to 90-degree studio, the warmth coddling muscles and helping to increase flexibility and release toxins. Jessica, Melissa, Abra, and company also impart fundamental postures in a pressure-free atmosphere during Power Yoga Basics held in a cooler studio, where they correct stances with hands-on adjustments, like science teachers who correct physics homework by actually becoming a human cannonball launched at a 45-degree angle.
