Parighasana (Gate Pose)

Start by kneeling with the knees and ankles together. Step the right leg out to the right and bring the foot inline with the left knee. Press through the right big toe mound, working the sole of the foot towards the floor. As you exhale, hinge from the hip to bring the torso over the extended leg and slide the arm down the leg and rest the forearm lightly on the shin with the palm of the hand facing upwards. Extend the opposite arm up and overhead and turn your gaze up towards the ceiling (or sky if you are outside!). Stay here for 30 second to a minute. Inhale to come out of the pose, step the kneesback together and then repeat on the left side.

This pose tones the oblique muscles of the abdomen, while side bending helps to relieve stiffness in the back.
