I could write a dissertation on why paying some attention to your breathing matters, but in this video I explain one reason.
The diaphragm is connected to the lower part of the rib cage, and really starts the abdominal cavity. Emphasis on the word cavity here, it is just an open space. In order for us to not be floppy we need to create pressure into that space. Proper breathing techniques can help to create proper pressure.
In this day and age we tend to breath all upper, and not lower. So use my quick exercise to occasionally to get some movement in the lower rib cage and help create more core control with your breathing.
