But seriously, everything you do regarding PT and nutrition should be focused on CRUSHING your PT test scores. Preparation and routine, like the others have mentioned.
During basic I had a Drill Sergeant nicknamed “Lucifer” stop me in the chow hall as I was making my way to a table with my tray. “PRIVATE, WHY DO YOU EAT SO MUCH FUCKING FOOD!!!???” I replied, sounding off “BECAUSE IT KEEPS MY PT UP DRILL SERGEANT!!!” He let me pass without incident.
One meat, one starch, milk (carton and glass), mini box of cereal, apple, orange or banana and two pieces of wheat toast, as much as I could grab. I did this for every meal, PILING everything on I could and then mowing it down FAST; and only using a large spoon that soldiers affectionately called an E-tool.
Then I pushed myself in every event, never letting up an inch, ever. I smoked myself everyday. When you’re young you recover fast and sleep like a rock, so it worked.
You don’t need any crazy formula. Just train hard, don’t half step, even when you think you can get away with it; integrity is something you have when no one is looking. When you you see someone struggling, pick them up, push them as well. Lead the pack. Your mind will start pushing your body. It’ll either break and you'll get recycled, or you’ll get stronger. It’s a spawn of the salmon event.
So again, no cosmic ritual, or magic bullet, just GET and STAY motivated...and it doesn’t hurt to eat like a VIKING!
