Lie flat on your back. Bend both legs at a 90-degree angle and let them fall to the right. With knees stacked and hips level, slide one or two pillows between your thighs. Extend your arms straight out at shoulder level and turn your head to the left. With eyes closed and jaw and belly relaxed, focus on feeling the breath flow all the way up into your collarbones. Stay for as long as you’d like and then switch sides, twisting to the left and turning head to the right.
