-Keep your shoulders, arms, hands and fingers relaxed
-Position your wrists straight or in neutral position while typing
-Adjust your chair height and position so your feet rest flat on the floor, or add a footrest to compensate for a higher chair
-Adjust the keyboard height so that your shoulders can relax and your arms are straight in front of you
