If you refer to the Focus on the Spine , (that you all already diligently read of course…;)), maintaining a good posture (neutral spine) helps you to breath and feel better. Good posture also involves good breathing and chest flexibility.
As we spend long hours working at desks or staring at computers, the tendency is to stay into a hunched position. So, our chest tends to be very tight. With time, chest tightness might alter or shorten your breathing. A flexible chest is actually a powerful ally to good physical and mental states!
How to gain flexibility in your chest?
In Yoga, the Bridge, among others, is a great beginner pose to work on chest flexibility and heart opening. In general, to open your chest, while performing a pose, squeeze your hands together behind your back, arms straight, and pull your hands up to the ceiling. While doing this, your shoulders are opened; your shoulder blades are squeezed; your chest is fully opened (please refer to the pics below). That is more challenging, but you feel so much better afterwards!
