Preparation: From a Forward Bend, take the right leg back so that the back foot is vertical and the front shin is vertical. Front knee should be directly on top of the front heel.
Execution: When it feels comfortable and balanced, bring the hands off the floor alongside the torso and in line with the back leg.
Notes: To work on flexibility rather than strength, simply bring the back knee to the floor and breathe deeply into the hips. Always work on squaring the hips up to the front of the mat.
