He first defines CrossFit as “constantly varied, high-intensity functional movement.”
Says Glassman: “One of the things that we’ve done that I think is critical to our success and perhaps unique to our effort even is that we’ve been very, very clear about, from the outset, defining terms.”
Glassman expands his explanation by defining functional movements through scientific means: “universal motor-recruitment patterns.”
“These things are unique in their ability to express power,” he says.
The importance of functional movements, says Glassman, is that “they will determine in no small measure the quality of your life moving forward.”
Glassman, however, has always preferred demonstration to explanation and tries to get people to experience CrossFit for themselves.
