Describe common posture problems.

Almost everybody exhibits bad posture during some parts of the day. Among the most common problems are flexed or sloping shoulders, a rounded upper back and a chin that juts too high or forward. Many people tend to extend their necks like turtles (especially when doing computer work), which can really stress the neck.

breathe deeply from your lower lungs - imagine a rubber ring around your waist (your diaphragm)

breathe in and try to push the ring outwards.

breathe in through your nose and out through your nose and mouth.
