Forging general physical capacity—and the will to earn it
In this 2009 conversation with Tony Budding, Coach Glassman discusses “primal fitness” as the development of broad, general physical capacity for real-world tasks—like swinging a hammer or sledge. While he would prefer these efforts be precisely quantifiable, he notes the current lack of tools to accurately measure such work, imagining innovations like force plates to capture output and accuracy. At the same time, he reflects on his training culture of hardship, arguing that meaningful achievement—in fitness or any domain—requires sacrifice, discomfort, and commitment. CrossFit, he suggests, naturally selects for those willing to endure rigor rather than seek shortcuts. Looking ahead, Glassman maintains that the CrossFit Games will continue to reward athletes best prepared for the “unknown and unknowable,” and that the core prescription of constantly varied functional movement remains sound.
