CrossFit memes began circulating in the early 2010s as the high-intensity interval training program exploded in global popularity. The humor usually targets the extreme enthusiasm of its practitioners, leading to the famous 'First Rule of CrossFit' trope: you must always talk about CrossFit. Other popular themes include the controversial form of 'kipping' pull-ups, the specific lingo like 'WOD' (Workout of the Day) or 'AMRAP' (As Many Reps As Possible), and the post-workout collapse. These memes bridge the gap between dedicated athletes mocking their own obsession and outsiders poking fun at the sport's perceived intensity and tight-knit community.
