Change and technical adjustment should be inspired by a desire for improvement, not just as a reaction to failure.

Recognize that water is a variable environment. Training should force micro-adjustments in every stroke to build an adaptable kinetic chain.

Introduce "perturbations" (small changes in pace, load, or stability) to teach the body to self-organize under pressure. :

Consistency and early discipline are the most effective ways to avoid extended struggles with technique later in a career.

Practice high-hand, elbows-up positions to ensure efficient propulsion and stay "on top" of the water. :

Focus on "mechanical tension" and the "early catch" (scapular elevation) as vital components of a powerful stroke.

Avoid a passive approach to training. High standards are necessary to prevent reduced skill development.

Target the "late breath" in young swimmers by teaching them to breathe while keeping their hands in front.
