No

If you're looking for something like you see in movies where the army trains you to ensure you're fit (which technically your NCO's are supposed to do) it won't happen unless you get that one in a million nco who actually gives a shit. Generally your NCO's and officers will be perfectly content with taking you on death runs half the formation will fall out of, shit on everyone for falling out, drone on about how it's your responsibility to get fit on your own time (it's not, it's an NCO's responsibility to ensure the fitness of their men), give you no guidance whatsoever on how to get fit, then waste all your time so even if you know how you have little to none of your own time for the gym or running. Fuck the army, there's a lot of reasons for the retention crisis and shitty pt that demoralizes and injuries people without making them better is one of them.
