Interesting the two concepts mentioned Capacity (gas tank) & Power (miles per gallon). Even more interesting is the fact that power is not defined solely by 'strength' but by efficiency (technique). I keep coming back to this because in my view, as a masters swimmer (without competitive background), you quickly learn that a good swimmer is not made by a body type (or relative age) but by the skill in moving through the water efficiently.
Wow this was awesome! One of the best episodes so far. He describes the work at Carmel with great confidence and clarity. It's great to have some insights on US club teams
