Which drill introduces the correct mechanics for the backstroke pull, emphasizing straight arm recovery?

The Backstroke Mechanics drill is designed specifically to teach swimmers the proper mechanics involved in the backstroke, with a focus on achieving an efficient and effective pull. This drill emphasizes straight arm recovery, which is a crucial component of the backstroke technique. By maintaining straight arms during the recovery phase, swimmers can ensure a streamlined position and generate more power during the pull phase.

Engaging in this drill helps swimmers develop muscle memory for the correct body position and arm movements, allowing them to integrate these techniques into their full swim. The other drills mentioned may focus on different strokes or aspects of swimming and therefore do not specifically target the backstroke pull mechanics in the same way.
