Hey! I resent that libelous remark! :mad:
We do NOT keep our hands in our pockets! 
Current Air Force, been in for nearly two years and still in the training pipeline (long boring story), so I can only comment on the training in the Air Force, and what I’ve been told about that mythical land of milk and honey known as the Operational Air Force™
If PT is a joke in Basic in the Air Force, it was a joke at my expense. Monday through Saturday we fell out as soon after 0445 as inhumanly possible shaved and tooth-brushed in PT gear with canteen belts and flashlights for morning PT. Typically it would be either strength-training (maybe three or four sets of 20 pushups, situps, squat thrusts, and mountain climbers, plus whatever else the Instructors decide we should do. If someone doesn’t maintain proper form, we started over) or Aerobic (two mile run or “Last Trainee Up”, basically you get into groups of 10 or 20 trainees, and the last guy in line sprints to the front of the line, and this goes on for two miles or so.)
Oh, and if someone left the toilet seat down, or if there was a mess somewhere, or if the instructor witnessed somebody laughing or being too loud, we’d do Motivational PT, which was more pushups and squat thrusts and flutter kicks (pushups suck on a waxed tile floor, BTW).
Before you can graduate Basic Military Training, you have to meet some minimum fitness standards: 13:56 minute mile and a half run, 27 pushups, and 50 situps for females in the Air FOrce. If you do a 13:56 run, 27 pushups, and 48 situps, you get one more try at it, and then you’re training for a week to try again.
I failed the fitness test by a fairly wide margin and got sent to the Get Fit Flight, which was for me two and a half weeks of character-building PT for an hour and a half at a time three times a day. It was fun in a “I never ever ever ever ever want to do any of that crap again. No not even if you gift-wrapped Alyson Hannigan for me. Well, maybe for that.” kinda way. It can last upwards of four weeks, and it used to be run by a couple of instructors who previously were a Sergeant in the Marines and a Staff Sergeant in the Security Forces. Not sure if it’s still around now though.
I have heard that Chief Master Sergeant McKinley wants to do Physical Fitness “Pop Quizzes”, where you’ll be tested for fitness with little or no warning, in addition to doing regular PT evals more often.
Lessee… what else… I’ve been told that BMT is now eight and a half weeks long, rather than six, but that’ll make probably no real difference to you. It’s still the shortest Basic Training in the Defense Department (Navy I think is about the same, Army is nine weeks and Marines eleven I think). Just do your best and take things chow to chow, day to day, and don’t stress over how many weeks you have left (and NEVER get caught keeping tally marks or a calendar, the instructors LOVE that). Basically remember that the point of camo is to keep you from being singled out by the enemy, and do your best to blend in.
Language-wise, in the Air Force, if you go Enlisted, they’ve got nothing for you to do with Japanese, but they do have quite a few airmen studying Arabic, Korean, and Chinese, not to mention Persian Farsi, Pashto, and a host of other languages (if they speak it in some unstable part of the world, the Air Force probably has someone studying it). The language training is very brute-force academically intense if you end up learning a language at the Defense Language Institute (where all of the branches send their guys to learn).
Another vote for waiting until you’re OUT of training to get married. No, I don’t care HOW perfect that guy in your brother flight is. Training is often stressful, and people do stupid things while under stress. There’s a running joke around here about people getting married at this tech school, only to get divorced at their next base. Wait to see if he’s perfect when you are free to act like normal people again.
So yeah, talk to the appropriate recruiters, do the research and figure out what YOU want to do in the military, and don’t sign anything until it’s set up how you want it, because once you’re committed, you’ve volunteered for whatever they throw at you.
