In "Power Position," Coach Rardin explains the proper position for the pitching elbow by comparing it to arm wrestling. People don't arm wrestle with their elbows extended. Instead, they keep their arm at a 90-degree angle because it is the natural position for the body to generate the most power. This is the type of simple, easy-to-grasp examples that makes Coach Rardin's pitching drills and skills training course so effective, memorable, easy to learn and easy to execute.
