Do not bring more shit than you actually need, cause like they said, when you head home you'll be carrying all that stuff plus all your issue kit and probably your class A's in a garment bag. It'll be a real friggin' drag too if you are going home on the Army's dime.
Physically you are actually in danger of LOSING conditioning unless you put in extra time in the barracks weight pile. If you really push yourself in PT though you are in a real good position to max out your events. You'll need to push REAL hard on the run though.
Pull ups are a secondary exercise at most. We did pull ups and chin ups before going to chow hall or when being punished as individuals or small groups. But the first time I had to do pull ups for a grade was in Airborne School. Seven pull ups was enough to continue. Most of the Army and Air Force guys had to work to knock out the seven or maybe nine. The Marines did better and the BUD/S graduates in the SEAL pipeline did pull ups for fun. Those jokers would start doing pull ups in slow motion, or would do ten and than hang at half pull until they fell off the bar...seriously. And if one BUD/S grad drew punishment PT, he'd do this bark and every BUD/S grad dropped and counted them out together. You'd have maybe twenty or thirty guys in a training company of 300 or so and they would bring the whole thing to a screeching halt because they had uncompromising unit integrity amongst themselves. When our training day was over, they would head out in boat teams (except for the guys who drew guard or other duty) and spend a couple hours at the Post Pool.
If you've got your shit really squared away, you MAY find yourself in leadership positions (squad leader or platoon leader) for an extended period of time. Out of 13 weeks of Infantry OSUT training, I spent 11 in leadership positions including two stints as Platoon Leader and the rest as squad leader.
People will try to pull crap on you. I had one shit for brains gang banger in my squad who plated a live round in my bed post. When it was found during a detail cleaning of the barracks, the DS questioned me briefly, said "yeah, I know you aren't that stupid. Carry on. Oh, by the way, drop and give me twenty, just because."
"Yes Drill Sergeant!!!!"
"one Drill Sergeant"
"two Drill Sergeant"
....
Another time the same A-hole decided to challenge me. He got right in my face, shoving, bumping chests, the usual macho B.S. garbage. I told him to secure that shit and get the detail done and over with. He continued his B.S. and the Drill on Duty that day heard the shouting and came to see what was going on. He decided that we needed to discuss our differences in a controlled environment (the punishment pit). We did a lot of pull-ups, then a pile of chin ups, then we pushed mother earth for forty minutes or so. I held out longer than the A hole, did more pull ups, more chin ups, and kept pushing when he stopped to rest. Probably did two hundred push ups in that counselling session, the last 40 or so in 1 or 2 rep sets, because that's all I had. The Drill Sargeant, after explaining to the A hole how much extra work I had to go through as squad leader, offered the a-hole my job. The guy refused it and I walked in soakin' wet and tired as hell, but vindicated.
Motivation counts for everything and being willing to do shit that others won't will win you respect. You'll be tired, but you'll be respected. By the end of the cycle, I got along real well with two of my Drills...the other was psycho. Very scary, very good.
