There's always something to think about while, say, running. Is my posture correct? Are my feet hitting the ground well? Is this a good pace? And lots and lots of self talk about not shirking the next effort (30s hard running, hill run etc etc).

Boring doesn't mean nothing to do. It means no interest in what is there. Not shockingly, people good at setting somewhat mundane objectives and iterating on them are good at both intelligence and exercise. They probably feed each other. :)

> Boring doesn't mean nothing to do. It means no interest in what is there.

Fair enough :)

When the first studies by Jaeggie on IQ came out a few years ago I hit dual n back pretty hard trying to improve my IQ. I don't think I got any smarter, but I did notice a few things. Pros My attention got better, I was less easily distracted. My executive function was better, I made better choices in life.(less junk food, fewer beers) My thoughts slipped less often, I had those "what was I just talking about" moment…

Those are all indicators of intelligence. Whether you have good executive control due to some "intrinsic" intelligence or due to some conditioning, the net effect is the same.

Not being sociable and fun at parties is a sign of intelligence?

Charisma doesn't come from the liver. (believe that was Yudkowsky)

Amusingly, I would not be surprised to find some people need both. In particular, exercise is boring. Very very boring. Anything that can help with concentration during boring tasks is useful. Obviously, that is my experience. Ymmv

It is only boring if you have a restless mind that wants to constantly preoccupy itself with distractions and run away from the slightest discomfort instead of being here and now. With some ZEN focus any activity can be interesting when done with full awareness. Sorry couldn't resist. Carry on.

I also thought "someone needs to do some mindfulness meditation practice or something and learn how to deal with that" as well. People rarely want to hear about it though.

This was how I felt about lifting weights. I know about all of it's amazing health benefits, but you've got 3-5 minutes rest between sets, with most programs having you do at least 9 sets total. That's not even counting the time added on if someone else asks to work in sets with you. Plus the need for a spotter when benching. Point is, I ended up getting into bouldering. If you want to send a bouldering problem, you…

I picked up bouldering a few weeks ago and I love it! I wish I'd learned about it sooner. I've never experienced such a satisfying muscle ache before.

Seems really fun! Couple reservations I have. Do you have to wear a harness? Are people going to be telling me what to do? Isn’t it expensive?

Try some exercise in VR. "Thrill Of The Fight", "Holopoint", "GORN" or similar games are a lot of fun and are at least a moderate workout. I've literally just finished a half-hour session of GORN, I'm fairly sweaty, and I wasn't bored once. (I also recommend similar things in IRL with Actual People, but I'm aware that those tend to be both more intimidating and harder to fit into a pre-set schedule.)

Do you know the best exercise for your brain? Actual exercise. Running increases neurogenesis[1] more than anything else. [1]: https://www.nytimes.com/2017/10/04/well/move/for-your-brains...

The link does not compare running versus other forms of exercise. It compares running vs no exercise. "Running increases neurogenesis[1] more than anything else." is not a finding in the article.

Here are a few more articles for you. Take your pick. ;)

This is actually a really common improv warm up. The group that's about to perform circles up, and one person says a word to someone else in the circle. That second person then passes the word to someone else, and so on. Eventually, after around 50 words, someone spontaneously passes what was said to them back and you start trying to go back down. The benefits are many, everyone practices focusing, listening and trus…

I don't understand. Isn't it just the same word you started off with? Actually, I probably misunderstand since it sounds like the whisper game but with public passings which obviously would make no sense.

Each word is pushing onto, and then popping off of a stack.

"exercise is boring". You are clearly very unimaginative when it comes to exercise. I find the gym pretty bloody boring. But whitewater kayaking, mountain biking, rock climbing easily beat sitting in front of a computer. If those are too much go for a hike in the mountains and take in some scenery. Or learn to surf. Or cycle to work. I get an hours solid exercise every day doing that and save myself time and money as…

Unless you live in say Salt Lake City or near a national park, these aren't activities you can do everyday on a schedule.

Cycling is fine, as long as you live in a place that supports it well enough (so a Deep South city with no bike trails might not be a good idea).

Did subjects improve their dual-n-back scores significantly during the exercise regiment? Did they improve on other memory tests? Did they improve in learning tasks?

I get that they got increased brain activity in areas associated with learning and memory, but I'd like to see subjects also improve when directly tested.
