Look at your elbows. Are they bent?
When we flex the elbows, the connection they have through the upper arm causes the shoulders to rotate slightly forward, which causes the Collarbone and chest to drop, the head to move forward, and a forward flexion of the spine occurs. The result is that deep and full breaths are replaced with more shallow breaths…not good for us narrators if we want to achieve breath control to get through long passages without gasping.
Try this: when you’re not bending your elbows to type or scroll, let your arms hang loosely at your sides. Feel how there is an openness and the chest and throat feel more unlocked.
Practice this in your daily life and enjoy the ease that comes with relaxed elbows
