Trooper
Shooter
I only wish I could be half as great as shape as trooper. After all, when it comes to "peak performance", I'd enlist the help of a good trainer or instructor, not talking to my PCP about how to attain such "peak performance" by running.
Or a physical therapist who does a similar function. I flipped a motorcycle when I was 16. But Desert Storm I had lost half of the muscle mass in my right leg. Even then I was still running 10:30 in the 2 mile. But too much sitting (riding vehicles, staff meetings, so forth) while in Saudi Arabia hurt me. Plus it was difficult to exercise and train in a combat zone. And I had contact with a soil fungus that induces pseudo-pneumonia that left scaring in my lungs.
