Aside from keeping your wits about you, there are few more important things than strength and stamina in a life-or-death situation. (Or even just when you don’t want to look like a mouth-breather in front of your friends—that’s arguably every bit as crucial.)

Whether you are a shooter, a fighter, or a hobbyist, your lungs are your real “first-line” weapon. Even if you are unarmed when you encounter a life-threatening situation, those lungs and that stamina will at the very least get you out of harm’s way, to fight another day.

It’s difficult to fully convey what happens to your body during a gunfight, but combat is hands-down the most physically demanding thing a human being can endure, besides curling. It is a test of everything you are made of. And the weak—guess what?—don’t inherit shit. They die, in a sorry, dirty, crumpled mess at the business end of a thunder stick, at the hands of the man who trained and fought harder than they did.

Over time I will hit on fitness frequently, and you will begin to see a common theme. All the cool-guy gadgets and optics and trigger jobs and new magical bullets in the world aren’t going to help you if you can’t drag your sorry ass from cover to cover to close with and defeat the threat.

Maybe I’ll just take up long-range precision shooting and bypass this. Right? Negative. I challenge you to drag yourself hundreds of meters, thousands of meters, through any kind of terrain and tell me you don’t want to whip that gun around and stick your toe in the trigger well. This applies to just about anything in life where danger is present. Not just combat. But for this audience, we will stick to that for now. Because, let’s be honest, we have a cooler hobby and job than anyone else.

You will be out of breath faster in combat than from anything else you could possibly imagine. Most of you know this, but for the sake of the article just bear with me.
