MuscleTech's ten nearest neighbors span fictional characters, MMA athletes, actors, TV shows, and musicians — with no other fitness brand appearing in the top 10 at all.
The shape is flat: scores run from 0.89 down to 0.85 without a single dominant pull. Thor leads at 0.89, a fictional character subcategory entry, followed by athlete Miesha Tate at 0.88 and actor Jeremy Renner at 0.86. UFC News (0.85) and Ronda Rousey (0.85) round out the top five. Tallying the subcategories across all ten: four are TV Shows (2 Broke Girls, The Ultimate Fighter, UFC Tonight, and one more), two are Fictional Characters (Thor and Iron Man), two are Athletes (Miesha Tate and Ronda Rousey), one is a News Publisher (UFC News), and one is an Actor (Jeremy Renner). The MMA thread — athletes, UFC media, and combat-sport TV — is the clearest cluster, but it shares space with Marvel fictional characters and mainstream entertainment, suggesting the audience composition extends well beyond a fitness or sports-supplement core. No other Fitness subcategory brand appears in the top 10.
The overall picture is an audience that indexes across action-oriented entertainment and combat sports rather than concentrating tightly around any single content type.
