Let this be a wake up call. You as an NCO shouuld be setting the standard, and it is up to you to keep your body in shape. Of all those in the Army, it is those that have "taken an APFT or two" that should not be the ones failing or even coming close to failing. You know what to expect at the APFT and know as soon as you are done taking one that you will have another in 6 months or so.
I have seen one too many NCOs trying to duck out of going to an NCOES course, and sometimes the chain of command really as no option other than make the NCO go because they already have a seat in the class for you. I would believe that that there is nothing worse for a 1SG than getting a call from some ticked off SGM at the NCOA because they NCO that he or she sent busted tape or failed an APFT.
Sure it is easy to put PT on the backburner, and I have been guilty of doing so in the past, but you just have to work that much harder to pay catch up.
If you are truely going to make a turn for the better, then there is no better time to staft than right now. Get out there and run. Buy some push-up bars and start working on your push-ups.
If I read what you posted above correctly, you have 11 years in. It sounds to me that you are planning on making the Army a Career. Maybe it is time that you start doing what you need to do to get promoted to the next rank. Complete BNCOC, smoke your PT, keep your weight down to a manageable level and lead from the front.
Don't become one of the many NCOs and Soldiers that pull the profile trump card right before heading out to NCOES.
I have to agree with ArmyReenlistment, but maybe it is time for you to turn to one of your fellow NCOs in our unit for that little bit of motivation you need to get ya going.
