Miguel,
First, to be able bodied enough to move freely and be a useful active person, (even if I have to hide the pain and soreness later ).
Second, to fulfill the oath I swore to the community I serve.
To have enough of a "cardio" engine, physical strength...
To do this leading from the front...
Firstly, thank you for your selfless sacrifice and devotion to duty.
If your movement has pain, then it is not free. This says either you're masking old injuries or you might consider changing your approach_to_training. Workouts that leave you fatigued, and that cause low levels of energy and deep muscular soreness, compromise mission readiness (Ciampa, A. 2013. Physical Training Culture), which is the very thing you should be avoiding due to your job requirements.
That involves carrying a gun or two vice a briefcase, which means you must be ready at a moment's notice, yet have the endurance to continue operations...
What is your version of "enough of a "cardio" engine", sir? I am learning that there are some very erroneous ideas and misconceptions when it comes to cardio. Increased cardiovascular capacity is the key to superior health (Ciampa, A. 2016. Maffetone, P. A., 2016. White paper)
As a leader, you have a very real obligation to coach, teach, and mentor your subordinates. If one of them told you, "hey boss, I think I'm "strong enough"", how would that go over with you? If you knew of a better way to train, would you share it with your men? Or recommend it?
I don't hold the keys, but I know the guy who does. If you're interested, hit me up, sir. If not, or until then, good luck with your training and stay safe out there.
