The Yoga Tree's passionate practitioners guide fledgling yogis and veteran gurus as they coax limbs into exhilarating asanas in vigorous Vinyasa classes. With the studio's accommodating class schedule, students can stretch sinews seven days a week during early-morning, evening, and weekend sessions. Within The Yoga Tree's tranquil practice room, students unroll personal or studio-provided mats while sunlight streams through windows that open onto views of the Merrimack River. Alarm clocks find new purpose in Sunrise Flow sessions, bleating their morning greeting to ensure pupils gather on time to loosen joints and center psyches with a vigorous series of Vinyasa postures.

The holistic Restore and Renew class calls on the therapeutic powers of Yin yoga and the subtle shifts of slow-flow Vinyasa to soothe the senses and assuage mental anxiety. Yogis and yoginis with limited mobility may lengthen limbs with the full support of props including blankets, bolsters, and marble busts of motivational speakers.

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