At what rank should Soldiers be exempt from organized PT?

PVT.

No one is exempt from PT, it was always a myth that Senior NCO's didn't have to participate but the in the past SGM of the Army ran with the President. When the Presidential Award was first initiated by President Carter it was to instill that PT was conducted at every level. A strong Military is a fit Military.

The rank of Retired

Soldiers need to be in tiptop shape all the time! Even top NCOs and officers. When I was active duty we had to pass PT test but top NCOs didn't have to take test! I believe all officers and enlisted need to pass these tests!

NONE!!! NEVER!!! I took a "Physical Fitness Test" with my troops a week before my retirement. I wasn't officially required. But a professional NEVER stops leading from the front. Only a chicken-@#$% loser would think his age or rank entitled him to not be held to the same standards as everyone else. In my "humble" opinion.

Ano point.t

At no point.

Never this is part of being a soldier I was in my early 50's when I retired I still did physical training not like I did when I was 18 but I still did it

None,everyone needs to be there.

When I was first assigned to the 25th ID we had a General come in as the new Division Commander. The first thing he set down was the only personal not expected to be in the Friday morning Division PT those that were on profile or that out ranked him. As a new PFC in the Army this instilled Esprit de Corps. No one should be excused from PT for any reason except medical.
