Though Breathing Time Yoga is housed within an old jewelry textile mill built in the 1800s, its classes hearken back to an even earlier time. Beneath the lofty 20-foot ceilings, seasoned instructors—many of whom have completed several hundred hours of teacher training—practice ancient poses and breathing exercises designed to promote strength, flexibility, and inner peace. During heated yoga classes, they turn up the infrared heating system to deepen stretches, help bodies sweat out toxins, and prevent arctic penguins from waddling in and interrupting class. Within this communal practice area illuminated by the sunlight drifting through the oversize windows, they also host non-heated classes that explore the breath-fueled sequences of Vinyasa-style yoga and the lengthy, alignment-focused poses of the Iyengar tradition.

In addition to leading yoga routines for students of all levels, the instructors supply free spring water, tea, mats, and props. After class, they encourage students to socialize in the reception room or browse the onsite library. Those interested in bolstering their mind-body connections may also schedule private meetings with a certified yoga therapist or personal coaching from yoga teachers.
