Begin in a low lunge with your left foot forward. You want your front knee directly over your heel and your back knee lifted off the floor. Make sure your front knee and toes point in the same direction. Bring both hands to the ground, one on either side of your left foot. This is your starting position.
Take a deep breath in, and as you exhale, lift your left arm up and twist your torso until your shoulders are stacked and your chest faces your left knee. Push your weight through your front heel, and keep pulling your abs in to make your hand on the floor feel light.
On your inhale bring the lifted arm down to the inside of your left foot.
Walk your hands to your right foot, bending your right knee, and shifting weight into the right heel. Straighten through your left leg, feeling a deep inner-thigh stretch.
Walk your hands to your left foot, coming back to the low lunge position again. This completes on rep.
