When using standard wrist action, the left wrist turns and cocks. At what
point in the backswing does the left wrist turn and is this a conscious act?
The Backstroke Turn Swivel is done in the Start Up. It is mirrored in
Release by the Downstroke Roll Swivel. So, you have a Start Up Swivel
and a Release Swivel. Finally, there is a Finish Swivel which
occurs at the end of the Follow-Through and completes the Stroke.
If these Swivels are already a subconscious part of your Stroke Pattern, then
note it and move on. If not, integrate them sequentially per 1-J and 3-B.
