Community: Feed, Groups, Challenges & Your Partner
How the social layer works: what is shareable and what stays private, plus groups, forums, challenges and accountability partners.
The social layer is optional, and its defaults expose nothing you did not choose to share. Read where the line sits before you post anything.
The privacy line
Read this part even if you skip the rest. Workouts, meals, PRs, check-ins and achievements are shareable. Bloodwork, vitals, compounds and contest-prep detail are private without exception: they can't appear in any shareable format, whatever your settings say.
The app enforces that rule itself, so no setting can flip it by accident. On top of it, your profile has its own visibility setting (public, anyone with the link, followers only, or hidden), and each post carries its own public-or-followers choice.
Health data has no share switch
No setting makes bloodwork or vitals postable.
The feed
Chronological, from the people you follow, with no ranking and no suggested-for-you. You write some posts yourself; the app offers to draft others when you hit a new PR, unlock an achievement or rank up. You can decline any of those prompts.
You can like and comment. There are no direct messages; coach conversation happens in the coaching layer.
Groups, forums and challenges
Groups are the smaller rooms: a training crew, a gym's regulars, people working toward the same thing. Forums are the wider ones, seeded by category (Training, Nutrition, Supplements, Progress, Form Checks, Off-Topic) with threads, one level of nested replies and upvotes. Reading a forum needs no account at all; posting does.
Challenges are time-boxed and can run across your followers or inside a group. They read from what you are already logging, so joining one adds nothing extra to keep up to date.
Accountability partners
Follows, the feed and leaderboards put your training in front of an audience. A partnership pairs you with one person who trains alongside you.
It is free on every tier on purpose: charging for the buddy in an app called MuscleBuddy would make no sense.
