Step your left leg to the back of your mat and bend your right knee for a deep lunge. Try to bring your bent knee directly over your ankle so your right thigh is parallel to the floor. Feel free to place hands on blocks to bring the floor to you.
Keep the left leg straight and strong with your heel reaching back. If this is too intense, you can drop your left knee to the mat instead. Stay five breaths before returning the left foot to the front of your mat next to the right one. Then repeat the lunge with the left foot forward and the right leg back.
