Backbends tend to be hard (but important!) because daily life has us rounding forward much more often than bending back. Anything that involves your hands and arms encourages rounding of your upper back and shoulders; and sitting tends to tighten up the front of your hips and compress your abdomen. For a comfortable backbend prepare your body by opening the front of your hips, lengthening your abdomen and side waist, stretching your chest, and lifting your upper back.
