Why does swimming twice as fast require four times the energy?

In this episode, Marina and Finn break down the brutal physics of water resistance. We move beyond "just pull harder" and explore the invisible forces holding you back.

Topics covered:

• The "Square Law" paradox (Why muscle loses to physics)

• The "Broomstick vs. Tree" analogy for body position

• Why the 2009 "Super Suits" were banned for being too fast

• The "Wall Test": A simple living room diagnostic for shoulder mobility

• A wild theory about future nanotechnology in swimming

This is a "Deep Dive" conversation based on 360swim's extensive library of coaching articles. It’s designed for background listening while you drive, work, or stretch.
