I've practiced at South Boston Yoga since 2009, and it is my home away from home in Boston -- incredibly welcoming community, fantastic classes, and a beautiful space. You can find range of high quality classes at all times of the day (vigorous vinyasa classes, aerial classes, pilates, hot yoga, meditation, ball rolling, yoga teacher trainings!), it is right on the redline, the studios have high ceilings and huge windows, there are great showers and lavender lotion, and it is filled with kind, talented, and thoughtful people. David and Todd (studio owners) in particular are two of the kindest, most committed people I have met, and have created a safe, welcoming, and warm space -- along with some seriously sweaty full body workouts. Highly recommend!
