I personally find that it takes a lot of love and patience. Try to stay in the pose for at least 3 mins. Focus on taking long inhales - with inhalations think of expanding the chest and the sides of the ribs, creating space. And work towards long exhalations - think of sinking and relaxing into the space you’ve created. After every back bend practice, make sure you spend time doing some counter stretches to keep the spine mobile and healthy.
