DO NOT SIT WITH SHRUGGED SHOULDERS
Make sure your work station does not force you to sit with shrugged shoulders (SEE ABOVE). If you use a keyboard, it should not be elevated so that your shoulders are in a perpetually shrugged position. Likewise, do not use an elevated desk or rest your elbows on the desk or arms of the chair, as this forces shrugged shoulders. The desk height cannot typically be altered, which is why it is important to use an ergonomic chair that can be raised and lowered accordingly.
