What does a kettlebell or training with a kettlebell have to do with data modeling?

Nothing, right? Or does it?

Kettlebell - Whether you're a regular person who's tired of being weak and soft, an athlete looking for a kick, or a professional with extreme physical and mental demands, you've come to the right place. (StrongFirst)

Data Modeling - Whether you're a regular person who's tired of being stuck with inaccurate and erroneous data, an analyst looking for a thrill, or a member of a profession with extreme demands for data quality, consistency, and integrity - you've come to the right place. (Dirk Lerner)

A not-so-serious analogy between a piece of sports equipment and data modeling to translate the benefits of sports to the world of data modeling.
