Working from breath, allowing breath to be deep, breath to move the body
Bhujangasana (Cobra) - Intended to broaden the chest area through breath, cobra is a great asana for opening the heart chakra. Not only does it promote spinal strength, but it also invigorates the circulatory system.
Garudasana (Eagle) - The arm and leg positions that make up eagle pose not only build strength and balance, but also open the fourth chakra.
Gomukhasana (Cow Face) - Like cobra, cow face pose strengthens the spine and stretches the arms, shoulders, and hips opening the chest and heart chakra.
Marjaryasana (Cat) - Cat pose is a great way to release back tension that may be keeping your heart chakra from opening.
Matsyasana (Fish) - A tremendous pose for improving spinal flexibility and strengthening the back, you might want to use a bolster for this one. When practised correctly, fish pose expands the chest cavity to allow the Anahata chakra room to fully open.
Urdhva Mukha Svanasana (Upward-facing Dog) - As it strengthens the spine, upward-facing dog also stretches the lungs and chest to open the fourth chakra.
Ustrasana (Camel) - This backbend asana strengthens the lower back, thighs, and legs while opening and invigorating the heart chakra.
