Inside the box

the long version

"CrossFit® is the gritty grassroots fitness movement that is fast making converts across the globe. [It] happens in rough-and-tumble spaces called boxes, with workouts forged from an eclectic mix of gynmastics, weight lifting, track and field, and plyometrics -- pitting athletes against each other to earn the day's top score. In this intense atmosphere where fitness is sport, Murphy discovers a surprisingly tight-knit crew all striving to sweat, suffer, and see who can push themselves farthest."--P. [4] of cover.
