Yoga provides a gateway to deep meditation, much like Rodin’s sculpture The Thinker or the hypnotic sound of Pat Sajak's voice. Cogitate sans puzzle-solving with today’s Groupon: for $39, you get one month of unlimited yoga (up to a $149 value) at Ember Hot Yoga in Woodstock.

Ember Hot Yoga helps students pose, sweat, and meditate their way to health through a limbering line-up of heated and unheated classes. The studio sets the thermostat at 95–105 degrees for each hot class, maintaining a 40% humidity level capable of transforming tree poses into saguaro cacti and wheel poses into sweaty tumbleweeds. As the temperature rises, yogis become more limber, inching closer to pose-nirvana with each sizzling stance. At Friday’s reggae-fueled Hot Power class, posture posses sculpt core muscles as they eject toxins and stress, while a seasoned teacher serves as the guide to Gumby idolatry, showing modifications for moves in order to make the class accessible to students of all abilities. In similarly steamy style, the Hot Flow Candlelit class turns up the heat as it turns down the lights, exploring advanced standing poses amid tea lights, tapers, and trick birthday candles. Unheated classes––such as Saturday morning’s Dharma II––focus on tepid stretches, twists, and backbends developed by Sri Dharma Mittra, an eminent New York City yogi. The advanced group also ventures into headstand territory, preparing practitioners for future careers as coatracks.

Ember’s 4,400-square-foot studio teems with positive vibes and deluxe accoutrements, including cork flooring and a high-tech heating system that filters and circulates air as it infuses the room with steam. Paper lanterns and rays of sunlight line the standard-temperature Zen Room, while the spa-like locker rooms welcome guests with Aveda shampoo, sparkling vanities, and shower-singing talent shows.

Though Ember Hot Yoga sometimes features a discounted price online, this Groupon still offers the best deal available.
