Stand at one end of your mat and take a giant step forward into a front lunge with your right knee bent and directly over your right toes. Slowly straighten your left leg and use your core muscles to gently twist your left elbow toward the outside of your bent right knee. (If this is too intense, drop your left knee to the mat and continue twisting.) Contract your abs, and avoid sinking your body weight into your right hip or knee. Look down at your toes (or up to the sky, which is more challenging). Hold for 3 to 5 deep breaths and lengthen the spine to deepen the twist at your waistline. Continue breathing through the nose and push up to standing. Switch sides and repeat.
