Freestyle Hand Entry & Catch-Up Timing: Clean In-Line Hydrodynamics

Flawless hand entry establishes the anchor point for subsequent propulsive phases.

Entering middle-finger first at a 45-degree angle in line with the shoulder prevents subacromial impingement while front-quadrant timing minimizes wave drag.

Adopting a 3/4 catch-up timing sequence maintains continuous propulsion while wide shoulder-line entry cures impingement.
