“What Is Fitness?” Part 3: Hopper Model

In Part 3 of this six-part series on CrossFit’s definition of fitness, Seminar Staff Head Trainer Jenn Hunter-Marshall explains the Hopper model of fitness.

The essence of this model is the view that fitness is about performing well at any and every physical task imaginable. Picture a hopper loaded with an infinite number of physical challenges, where no selective mechanism is operative, and being asked to perform feats drawn at random. 

“He or she is fittest that statistically performs the best on these things,” Hunter-Marshall says. “Here we’re looking for a balance of skills and drills, and also a way to test who’s fittest.”
