One concept the CrossFit Level 1 Training Guide spends a lot of time on is deceptively simple: “What is fitness?”
At first, it seems like an easy question. You might say it’s about being strong, having endurance, or just “being in shape.” But once you really start to unpack those terms, you realize how vague they are. What does strong mean? What kind of endurance? Compared to who?
Greg Glassman, CrossFit’s founder, pointed out that despite the size and influence of the fitness industry, there was no universally accepted, working definition of fitness. No way to objectively say, “This person is fitter than that person.” It was often based on looks, arbitrary metrics, or specific sport performance.
CrossFit changed that.
