#273--When working out unilaterally, always begin with the non-dominant side. This allows you to give more neural drive to the side which needs it more before movement-related fatigue degrades motor learning and performance. Non-dominant is defined as the side which is weaker, less coordinated, or injured. For example, a person who is right side dominant but comes in with a hurt right knee should begin training on the right leg before training the left. So don't move around the gym on auto-pilot. Think about why you're there and have a reason for every detail in your program, including which side you exercise first.
