Start in Down Dog. Step right foot forward and place it beside right thumb, lining up right knee over right ankle. Lower left knee to floor. Raise torso and sweep arms above head with palms facing. Allow hips to settle forwards and down until you feel a stretch in front of left leg. Draw tailbone down, lengthening lower back and engaging core muscles. Stay here, or raise back knee off mat for a full Crescent Lunge. To release, place hands on mat and step to Down Dog. Repeat with left leg forward.
