From Wide-Legged Forward Bend D, plant both hands at the front of your mat, and step both feet back, coming into Plank.
Move your left hand over to the right so it's at the middle of the top of your mat. Roll over to your left side and plant your left heel down so you're balancing on the outside edge of your left foot, stacking your flexed feet.
Reach your right arm above you, gazing at your hand. Stay here for five deep breaths, trying to keep your core strong and the pose steady.
Lower your right hand to the mat and repeat Side Plank on the right side.
