Two fitness supplement brands anchor Bodybuilding.com's top 10, but the rest of the neighbor set belongs almost entirely to video games — a cross-kind split that defines the shape of this audience.

BSN (0.81) and MusclePharm (0.80) are the two peaks the shape flag names: both are Fitness-subcategory brands, and both score noticeably higher than every other neighbor. After them, the similarity scores drop into a dense gaming cluster. Destiny 2 (0.75) and Bungie (0.73) lead that second group, followed by Xbox Support (0.72) and Minecraft (0.72). Rounding out the top 10 are Anthem (0.71), The Division 2 (0.69), SMITE (0.69), and Sea of Thieves (0.69) — all Video Game Franchises. That means eight of the ten nearest neighbors are gaming entities, spanning franchises and a game developer, with no other Fitness brand appearing in the top 10 beyond the two leaders.

The two-peak structure is unusually clean: a tight fitness pair at the top, then a sustained gaming plateau below it, with no overlap between the two clusters in terms of subcategory. This audience shape suggests Bodybuilding.com draws a crowd that is simultaneously deep in fitness content and heavily represented among console and PC gaming communities.
