^ Interesting, and really begs the question: why does evidence, even scientific, shows us that the brain is actually physically wired so as to reject exercise?
easy
were evolved to a paleolithic world without the benefits and conveniences of modern society.
our bodies are used to starving, then gorging on food, then going on light food, then starving a bit, then engulfing a wolly mammoth or two, so on and so forth.
our bodies are used to expending enormous amounts of energy to get a bite to eat, which may or may not be scarce. our bodies are used to having to work around the consumption of many other hominids as well, who often want the same sources for food.
thus, our bodies are evolved to be lazy. this is evolutionary beneficial. if your body is hard wired to expend as few calories as possible when performing any activity, you will in turn save calories. most theories predict that the neanderthal died off because they couldnt meet their 3500 calorie-a-day needs, where homo sapiens could get by on 1500 calories if need be. perhaps neanderthals could bench press a bulldozer, but they required a lot more food than us (and ate almost all meat).
in a world without agriculture, you want to expend as few calories as possible, in order to survive until the next meal. your next meal may require you run as fast as possible, use every muscle in your body to force sharp objects into a creature 10x your size, and afterward you may have to use all of those muscles to rend its flesh, skin, and bones free from the kill. this requires massive amounts of energy, so now you have to eat more than you spent. not exactly an easy life, so if your body naturally wants to do this as energy-efficient as possible, it will have an inclination to be "lazy."
civilization has only been around for 5% of the human experience. were not exactly "adapted" to it, and doubtful we ever will be, as the benefits of civilization dont exactly provide for an environment to evolve in.
so for 2-500,000 years, we were out scraping the world for food with whatever energy we had. then in the last 10,000 or so years, food became damned easy to come by, but our bodies have changed little.
think of this when bodybuilding: one of the biggest problems new bodybuilders have is *not* recognizing how lazy the human body is.
firstly, that feeling you get when you think "oh, this is too heavy, i cant lift this" starts at around 60% of your total load bearing capacity. thus, most newbs to the gym give up without realizing they certainly CAN lift a hell of a lot more, their meal simply isnt dependent on it, so their lazy body says "give up, dont waste calories, etc."
this also effects posture. in my 8 years of weightlifting, i rarely saw good posture. theres the meathead on the bench press screaming his lungs out with both arms at uneven intervals, the bicep curl guy throwing his back and neck into it, and the dude on the ab crunch machine using gravity and momentum to force the weight down. our bodies naturally do everything with the least amount of effort possible, thus few people have good posture in a gym. good posture isolates the muscles youre working on, which is extremely energy inefficient. in fact, bodybuilding is exploiting our genetic makeup: were not designed for it, but we can bend the rules to grow ourselves the way nature doubtfully would (given how food is available now).
what i mean by posture is as follows: you grab a freeweight and start to do a bicep curl. then your mind wanders to what youre doing after the gym, or perhaps that attractive person across the room, or maybe the crappy song on the radio. you stop devoting 100% attention to the curl activity, and you start to use your back muscles a tiny bit. next thing you know (or perhaps dont know), your neck is straining to bear some of the load, and shortly after, you actually start pumping your thighs a bit to boost that weight up. then you start using gravity and inertia to move it up and down, and before you know it, your bicep is doing very little work, and youre not getting a very good workout (and of course wondering why you spend so much time in a gym without good results).
all of this is your body's natural inclination to be lazy. in a paleolithic world, healing from "bicep curls" would require so much protein, and other food-resources, that youd likely die from ketosis or starvation. in the modern world, you grab a protein shake and hit the shower.
so yea, our bodies are evolved to resist work. it kept us alive in a very dangerous world.
Only got 295 lbs of weights total though to use![:\](https://bluelight.org/xf/BL_Images/Orig_Emoji/wrygrin.gif "wry grin :\")
