How to do Matsyasana? 

• Lie down flat on your back. Keep your feet together.
• Place your hands on the floor, palms facing downwards. Move your hands beneath your thighs, close to your buttocks.
• Keep your forearms firmly on the floor and lift your chest up by weighing down on your elbows.
• When your chest is off the floor, lower your head back till it touches the floor.
• Ensure that your elbows, and not your head, bear the weight of your torso.
• Breathe evenly as your body is now an arch. Maintain the posture for around a minute.
• To unwind from the posture, lift your head off the floor and straighten your back. 
• Now, lower your torso completely onto the floor. Relax your body.
