Waves tumbling across sand is one of the most relaxing sounds. It is appropriate, then, given the name of her studio, that instructor Sue Wattenbarger has a soothing voice that doesn’t disturb the sense of calm in a room full of yogis. She calls on that calm demeanor, along with more than 200 hours of training, to guide students through restorative yoga classes. Sue specializes in lymphatic classes that help circulate fluids in the body and strengthen the immune system. The staff there is also experience with guided relaxation massage and yin yoga, which uses longer poses to increase mobility in the joints or make hiding in the National Mannequin Museum all day easier.
