The students in Nandini Weerasinghe's yoga class are strapped to a wall a few feet off the ground, bending toward the floor and feeling the effects of weightlessness as they stretch.
"We're working on decompressing the spine," Ms. Weerasinghe tells her class. "Use your breath to move oxygen along the spine." There are dozens of places in the Washington area where one can do yoga on a mat, perhaps using a block to increase the stretch. However, Beloved Yoga in Great Falls (www.belovedyoga.com) is the only local spot where yogis can pose while tethered to a wall, allowing them to break the bounds of body weight and gravity and free the stiffness along their backs.
