You might not like it, but AI can totally give you a recommendation of similar bands.

Not what you’re searching since it has no social components and is not for gym workouts, but I really like Geoactivity Playground. It takes your Strava Export or uses your GPX files and does really interesting statistics with it. Kind of like Veloviewer, but selfhosted
