Place a cushion, blanket, or yoga mat beneath you to cushion your knees. You can cross the front of the one ankle over the back of the other (with feet pointing out to the sides) if that feels better. If kneeling doesn't feel good to you, take any other comfortable seated pose. Palms can be placed firmly against your knees with fingers splayed out. Draw breath through your nostrils until your lungs are full. Lengthen through the crown of your head and draw your shoulders back as you inhale to ensure your lungs are completely expanded. Close your eyes as you inhale. After you inhale, open your mouth wide as if you were at the dentist. Stick out your tongue and lengthen the tip out and down so that it extends towards your chin. For a more intense option, open your eyes wide at the same time that you open your mouth and bring your gaze upward. The breath should pass over the back of your throat and make a distinct "haaaa" sound. Imagine you are trying to fog up a window with your breath. You should feel the muscles in the front of your throat contract. Press down through your palms as you exhale. Since the exhalation of simhasana is meant to release negative energy, it is important that it remains powerful throughout your practice. Therefore, it is best to repeat Lion's Breath only a few times in a row so that you don't lose the strength behind the breath. If the strong exhalations make you feel at all dizzy, take a break from the pranayam and breathe normally for a few minutes. You can place one hand on your chest to help regulate your breath pace.
