At what rank should Soldiers be exempt from organized PT?

Only once u have retired from the military. Reason. If ur in active status u could be going into action at any time. And I do not want some out of shape idiot shortening my life cause we have to take special care of him or her cause they cannot perform at their max.
And if a person that is in the military and wants to be allowed to not do PT because of their rank. Then they should be taken to put their signatures on paperwork for a dishonorable discharge cause they willingly decided to not fulfill their contract.

Retired !

Civilian

Never, even Generals should do.

In the Marines no rank should be exempt from PT.

As long as they are in the military, regardless of age they should be in shape weather its organized PT or PT on their own. They should have to pas the PT test annually.

I realize this is old but I couldn’t resist. At no grade. Even the leadership at each level should rotate daily doing PT with subordinate elements throughout the week. Setting the example is portrayed in all that we do. So, Master sergeants and staff officers get in there. Leaders at all levels, Company, Battalion, Brigade, Division, I think you all get the picture.

I think that is order to set the example for soldiers, all ranks at the unit level should be required to do PT if it is required of the lower enlisted

Their should be no exemption.
Lead by example.

No rank should be exempt from PT from E-1 to O-10. Especially senior officers that find themselves sitting behind a desk all day. I was Infantry and 6 days a week we did PT at 5am with our Cpt. Linwood P. Bailey, out front leading the pack every day with 1stSgt Wong, I'll never forget them, and his Lt's better be with his people. But this was in the 70's. At a time when the Army was a lot different than today.
