In all honestly mooka, anyone can do it. There were a lot of people in my company who probably would have said the same thing you're saying now. PT isn't everyone's thing. There were people who couldn't pass the minimum basic training requirements, but came out passing in the end. If exercising ain't your thing, then that's you. But if being willing to adapt to exercising ain't your thing, then it probably isn't in your best interest. Most people had some kind of issue in basic training be it missing home, exercising, authority issues, waking up issues (everyone) etc. But basic is meant to throw that shit out the window and force to you to adapt. If you want it, you can do it. If you don't truly want it, that'd soon become evident.
