What progression is characterized by "Thumb, pinky, pull" in the backstroke?

In the context of backstroke technique progression, the phrase "Thumb, pinky, pull" emphasizes an important aspect of the stroke mechanics where the thumb enters the water first, followed by the pinky finger, and then the actual pulling motion through the water. This concept is essential for teaching swimmers the correct hand entry and recovery phases of the backstroke to ensure efficient propulsion and minimize drag.

The progression of 25 yards is typically associated with a more advanced skill level in swimming, where learners have developed enough strength and coordination to implement the full mechanics of the stroke over a longer distance. This distance allows instructors to help swimmers practice and refine the timing and rhythm of their strokes, making it beneficial for reinforcing the "Thumb, pinky, pull" technique within the context of longer-lasting endurance and efficiency in the water.

Shorter distances, such as 7 yards, 15 yards, or 50 yards, might not provide the same opportunity for learners to properly apply and maintain the technique over a sustained effort, as 25 yards strikes a balance between distance and skill mastery necessary for effective instruction in backstroke.
