All fast swimmers create propulsion with the same key principles, but they use different positions to make that happen.
That’s even true of individual swimmers.
They may execute effective pulling skills on both sides but do so with different positions.
Check out this swimmer.

He’s doing a great job holding water with both arms, but they’re not identical.
Which one is deeper versus shallower?
Which one is straighter versus more bent?
Which is wider and which is narrower?

This asymmetry can arise from the effects of breathing and rotation, or just because of differences in range of motion in the upper body.
It’s not about the positions, it’s about the principles.

Swimmers have to create a big pulling surface area, they need to hold that surface area, and they need to accelerate throughout the stroke.
When swimmers make that happen, they go fast, even if the positions don’t look exactly the same.

One of the biggest values in creating a skill development system is that it creates clarity.
Clarity leads to action.
Action leads to results.
Coaches know what needs to get done.
The skills and fitness to be developed.
