Stand straight with your back against a wall, slightly pressing your back so you can feel your whole back against the wall.
Then, raise your arms and bring them back against the wall.
Slide your arms up and down against the wall, going as high as you are comfortable.
While doing the wall slides with the back of your head still against the wall, bring your chin down and tuck it into your chest.
Repeat this chin nod at least 2 to 4 times while in the same posture.
Return to the starting position, relax, and repeat the above steps.
