My insurance offers reduction if you pass a basic health check each year. It's kinda nice but also sets up a slightly adversarial relationship with my doctor, which I don't like.

Ideally the health checks would be done with someone else, to reduce that adversarial conflict of interest problem.

Maybe your doctor should even get a small reward each time you pass the basic health check, so that in aggregate they are better aligned with keeping people in shape for those checks.

I've seen plans that subsidize gym memberships.
