At what rank should Soldiers be exempt from organized PT?

If they are in a location where group /organized PT is available, rank should have no more exclusion than it would from required Physical Fitness Standards.
Understandable exceptions being:
Medical,
Work shift,
Location.
Other than that, I would consider The Chief of Staff joining us in a group PT to be most motivating & a positive example.
Isn't that an important part of what *leadership is about?

never! This is how you grow undisplined fat asses!

Whatever rank/position they have to reach to exempt EVERYBODY from PT. Sorry, but anybody that reaches a rank that they believe exempts them from anything lower ranking soldiers do, doesn't deserve that rank in the first place. Sure as hell not a leader.

Civilian That said, PT should be scaled for the older officers/NCOs. But leaders lead from the front.

They should be required to do that as long as they lead Soldiers. In my opinion, part of organized PT is esprit de corps. Not good when the whole unit knows their commander never does PT and the leadership clearly does one-on-one APFT with said "leader." Really kills the whole morale thing when someone gets special treatment.

POTIS

Never; as one goes up in rank, one also goes up in wisdom. There is no better way to spread the wisdom than during organized PT!

Rank? None. Duties, duty hours and profile ... OK, I get it.

We could debate this all day. I fully understand personal achievements and individuals being rewarded for that but as unit, PT is one of those events that help build cohesiveness when it's done the right way. So my answer is unless they're about to retire or ETS no one should be excluded because of age.

Never. I once ran PT with a 56 year old division commander. You can't expect soldiers to stay in shape if the boss won't. Oh and he preferred hot afternoons to cool mornings. Guy liked to killed me. :-)
