In my opinion, you personally design your routine of direct and indirect exercises for the training and/or test you are about to encounter.
I was an army reserve officer (Officer Candidate School, OCS), and had taken regular Army Basic/AIT training at Fort Sill, Oklahoma, and Law Enforcement Basic training, in Hutchinson, Kansas-----Friggen----> bring em'.
I got out of Law Enforcement due to an injury, and by an angry wife who didnt want me "on the street" as a Law Enforcement Officer any more. However, after several years out (and losing my certification), I went back (to get recertified) to Law Enforcement Basic at the age of 46 and trained along side persons half my age.
My personal motto during my training:
You may be bigger than me, you may be stronger than me, but the engagement of battle will be so brutal, though you may have won, you will think you have lost, and you will not be back.

Continue the fight!
It was logic that told me that no matter how much I trained at 46, that a comparably trained and conditioned person half my age, was going to be a step (or two) faster due to youth, but I am not logical in this sort of thought process....
I was the second in fitness in my class. Average age: 24.
You are going to need a training routine that is mainly and proportionate to
high endurance:
If you are going to join the US Army do a search on the Basic/AIT training methods and what they will EXPECT from you.
Here is a brief description on what to expect (I wrote it fast so bare this in mind):
1. 400+ pushups or more (per day) in boot camp isnt uncommon. Hundreds more if your not doing grass drills for someone in the company or you making a mistake in the "traditions" (i.e. boots being shined to the Drill SGT's satisfaction, inspections, urinal cleaning, uniform presentation, etc, etc.). These pushups do not include normal fitness training and routine scheduling.
2. 300+ situps or more (per day) in boot camp isnt uncommon. Hundreds more if your not doing grass drills for someone in the company or you making a mistake. This does not include normal fitness training or scheduling.
3. A steady dose of mountain climbers unil you wake up and see that you have been doing them while you were asleep, about 300+ per day or hundreds more dependent on whether you or another company member makes a mistake.
4. Prepare for 4 hours of sleep: The first few weeks you will get about 4 hours per day of sleep. Sometimes you will be selected for "fire drill" which means you get virtually none in one day sometimes--the first few weeks of Basic.
5. The ability to handle someone in your face constantly putting stress on you--ALL DAY LONG, with exception of classes. If you find it funny (as I did when I was in), "he tells you to get your D@CK in the dirt", if you look at him, "your d@ck is in the dirt", etc. Every where you go there is no walking--its all "DOUBLE-TIME........ALL THE TIME"--there is no walking.
6. You run about 3 miles in the morning after fitness training, and then another 3 miles in the afternoon after fitness training (and this doesnt include the hundreds of pushups, situps, mountain climbers during grass drills INBETWEEN), and all the while getting about 4 hours sleep per day. The 3 mile run in morning and the 3 mile run in the afternoon, is just the "break-in" miles, they get progressively LONGER.
7. A high endurance application of cleaning pots and pans on "Mess Detail". LARGE POTS all day for HOURS. Regular and on going "Latrine Duty" cleaning toilets, urinals, and mopping floors.
8. Attention to detail in barricks, self, and for inspections--if you make a mistake (even if its common and understandable) its NO EXCUSE...d@ck in the dirt for "grass drills", and these can last for 30 minutes or more sometimes. Think of all the pushups you can do in one day. This isnt enough.
9.
10 mile, 15 mile and 25 mile marches with full gear and backpack (with M-16, and pack can weigh 15 to 45pounds). Many BLOOD BLISTERS common. Many ankles swell beyond recognition. If you cant continue, one is out. Have to repeat basic after healing.
10. Obstacle course drills and time requirements. Must pass or out.
A very high mental and physical fitness is required. I did this off of memory rather quickly, so its not exhaustive. I took my basic at Fort Sill, Oklahoma (1984), and Officer Candidate School (OCS,which is WORSE) 1988, and my first Law Enforcement Basic in 1990), and a recertification (after being out several years), in 2007.
Are you aware this is what you are heading for in Basic/AIT Training in the Army?
Your training needs to be in high endurance methods of application. And, you need to have mental high endurance to withstand lack of sleep and tiredness in addition to high tolerence to pain.
Best wishes to you.
