The standout quote for me: "[immune cells] moved elsewhere, migrating to the animals’ guts or lungs, portions of the body that might be expected to need extra immune help after hard exercise".

Rapidly producing immune cells during exercise, then letting them (and more) die off would be a baffling response. But pumping them into the lungs (because you've been breathing hard through your mouth) and gut (for when you make up lost energy, and maybe eat some raw meat you've been hunting)? That makes a great deal of sense.

That effect is unconfirmed in humans, but it would ground our observations in an evolutionarily-sane outcome.

Exercise pushes stuff around in your gut which is probably more directly related to the immune response than the possibility of eating raw meat.

Why would you go run (hunt) if there is still stuff (food) in your gut.

This article doesnt make mention of my workout where I lift something heavy 1 time.

I had the idea that I wanted to reduce time in the gym, so I used the potential energy equation

PE= Mgh

I'm not getting any taller, so the only thing I could change was either the reps or mass of weight moved.

I made it my goal to lift heavy weights so I'd only need to deadlift 1 time and be able to pig out.

TBH, it works, I lose 1 lb a week eating 3,000 calories a day. We lift 2 times a week. Warm up, then do 2+ reps of a heavy set.

I dont really sweat after a workout, but I look pretty big and I'm still deadlifting 450lbs. But I only deadlift that weight 1 time a week.

Is that 'Strenuous'?

So you do 1 Rep Max once a week. Not bad advice.

How many warm up sets do you do?

Earlier quoted context omitted.

Best to hunt when you are loaded up on fuel. Don't want to be hunting when energy is low as you will most likely be less successful as your focus, patience, and response times will all be lower.

Hunting isn't like going to the store, success isn't guaranteed.

I gotta stash this one away. I often refer to the disaster of 20th century health science as scientists repeatedly gathering a single point of data and then drawing a line (or hyperplane) though it, but this is a great article clearly demonstrating an example of that, and how plausible it all seemed at the time.

(Not that it's a trend limited to the 20th century. But it seems to me to have been extremely bad in the health area in that time frame. Not uniquely so necessarily, but quite bad.)

Considering the article example is a marathon (26.2 miles, burns ~2600 calories) and your example is deadlifting (4 sets of 8 deadlifts @ 175 kilograms burns ~100 calories - equivalent of running .5 miles).. I'd define this test case as 1.9% as 'Strenuous'.
