Why you should include backbends/ heart openers in your yoga practice? Through heart-opening asanas you gain new strength, not only physically but mentally. Backbends bring the chest into alignment, train your spine and relieve neck and neck muscles. In short: Backbends have a positive effect on your digestion and your immune system and increase the oxygen supply in your body. You should definitely work very mindfully, consciously and concentrated to strengthen your body awareness, but also to avoid injuries.
Have fun on your yoga mat!
