Our read on r/Fitness

r/Fitness is the 1st largest of the 18 communities we track in Fitness & Health, with 12.6M members. Across Nichory's full directory of 363 communities it ranks 12th by member count.

At around 18 years old it is a long-established community. Older subreddits usually have settled rules, active moderation and high trust — but also years of archived posts, so a question that has been asked before will be sent to the search bar. Bring a specific angle.

Its Nichory signal score is 10/10 — our blend of audience size and how fast the community has grown per year. Scores this high mean an active audience that is worth writing for properly.

We could not confidently classify this community's self-promotion policy from its published rules, so treat it as restricted until you have read them. When in doubt, comment helpfully first and save any sharing for later.
