How many of us exert ourselves and then try to shoot?

We'd need our own range.  Maybe some privacy.  The strict bench rules of a crowded public range might not be the best place for such experiments.

I was thinking, a buncha pushups, pullups, and sprint a couple hundred yards.  Then immediately, while you are still huffing and puffing, heart pounding, sweat in the eyes, pick up a rifle and from the standing position try to get meaningful hits 100 yards away.

A Marine buddy suggested this after I told him about the seasickness test I saw on Firearm Blog.

He shared it is nigh impossible to get an aimed shot off while wearing MOPP gear.  That's the anti-chemical suit.  At a minimum the lens fogs up.  Cheek weld is problematic.
