I recently attended a yoga class in which the instructor had us flow through this twisted backbend variation on high lunge, and I just loved it! Start in high lunge with the left leg forward and right leg back, making sure the left knee is right above the ankle pointed toward the second toe of the foot. Keep the back leg long without locking the knee, and press back through the back heal. Breathe.
If this next bit feels a little awkward, you’re probably doing it right. Keep your base strong and on an exhale, lower the arms to shoulder height, extending the right arm forward and left arm back, thumbs up toward the ceiling. Twist the chest toward the left, and turn the gaze toward the back hand, if that’s available to you. Keep contracting the obliques (the side abdominal muscles) and resist the urge to lean forward. Breathe.
Contract the abdominals, and on an exhale, lower the left hand down to the back thigh and turn the right palm skyward. Inhale, extend the hand upwards so that the palm of the hand faces the back of the room. As you exhale, begin to back bend to your degree. Keep breathing.
To get to the same sequence on the other side from here, inhale out of the backbend, exhale to windmill the hands all the way down to the floor, and cycle through a two- or one-legged vinyasa. From downward facing dog, step the right foot forward and inhale the arms up into high lunge.
