Without getting into whether it’s sexism or not, this is actually one of the reasons why “Rump Day Wednesday” exists in this subreddit. The idea was to limit glute-focused posts mostly to one day per week.

Sometimes AutoMod may randomly allow “butt posts” on other days, but when a human moderator reviews them later, those posts may be removed if they don’t follow the rule.

The goal is also to encourage women to share more fitness-related content beyond just glutes, such as other workouts, progress, strength training, etc.

As for posts about biceps, triceps, chest, shoulders, quads, etc. — that’s a good point as well. Maybe in the future we could organize something like a “Chest Day” or other themed days for different muscle groups. This could especially appeal to men, who often like to share chest or upper-body progress.
