Why Resolutions Keep Lasting Three Days, and How to Train the Frontal aMCC: Reading

One line of a book flips the frontal lobe switch

There’s one brain region that comes up a lot in neuroscience lately: the aMCC, or anterior midcingulate cortex. Interest has jumped as word has spread that this region, tucked just inside the frontal lobe, is closely tied to willpower and focus.

And the method named for strengthening the aMCC isn’t some grand brain-training program but, surprisingly, reading. The idea is that just doing something you already do every day a little differently gets the brain to respond, and it’s only natural to wonder at first whether that can really work.

In this post, I’ll go step by step through exactly what the frontal lobe and aMCC do, why reading is named as a way to train them, and how to read so that it actually has an effect. It’s worth a read before you blame your three-day resolutions on weak willpower alone.

The frontal lobe and the aMCC: what are they, anyway?

The frontal lobe is the frontmost part of the brain, responsible for making plans, judging and regulating emotions. Put simply, you can think of it as the brain’s “control tower.” When the frontal lobe works well, it becomes easier to stay focused and resist impulses.

The aMCC sits right against the frontal lobe and is known to become especially active when we face something hard or something we don’t want to do. Many say this region is involved in the moment you want to quit a workout because it’s tough, or the moment you want to drift off while studying.

That’s why the aMCC is often compared to a “willpower muscle.” The idea is that, like a muscle, it develops the more you use it and shrinks when you don’t. The catch is that to strengthen it, you can’t just pick the easy things; you have to keep repeating activities that are a little beyond your comfort.

Maybe it’s not weak willpower, but an underused aMCC

When we give up on a diet or study plan after just a few days, we tend to blame ourselves: “I have no willpower.” But from a neuroscience point of view, this may be less a matter of character or grit and more a difference in how much you’ve been using your aMCC day to day.

A brain used only to easy stimulation sends an avoidance signal the moment things get even slightly uncomfortable. On the other hand, a brain that has often endured slightly demanding things has a bit more staying power left in the same situation. So “building willpower” really isn’t much different from “stimulating the aMCC often.”

What matters here is that it doesn’t have to be something extremely hard. A slightly uncomfortable activity at a level you can repeat every day is enough, and that’s exactly why reading, the most accessible of these, is singled out.

Why reading, of all things, trains the aMCC

Videos and social media are designed so that short stimuli switch quickly, letting you keep watching without your brain working very hard. A book, by contrast, makes you follow the sentences yourself, link up the context and predict what comes next as you read. This process itself makes you use the frontal lobe and aMCC continuously.

The key is the repetition of bringing your attention back to the sentence each time your focus wanders while reading. You can think of the process of “drifting into other thoughts and coming back to the book” as aMCC training in itself. The effect is greater with a book that takes a little concentration than with one so fun it reads itself.

More important than paper versus e-book is uninterrupted reading time. If you read in fits and starts with notifications going off, your brain has to spend that much more energy getting back into a state of immersion, so the key is securing time without interruptions, even if it’s short.

How many minutes a day, and how should you read?

If you try to read for an hour a day from the start, you’ll wear out within a few days. Since the basis of brain training is consistency, it’s realistic to start short, at around 10 to 15 minutes a day. Even if short, repeating it at the same time every day is known to be more effective.

The genre you read is worth some thought, too. If you only pick books that read too easily and lightly, the brain has little to work at, which can weaken the training effect. Then again, choosing a very difficult textbook or a thick classic right away will make you give up quickly, so it’s best to start with a book that requires a bit of concentration.

Keeping your phone out of sight while you read is also surprisingly important. Every time a notification pulls your gaze away, you have to repeat the process of getting back into focus from scratch, so your brain gets far more tired even in a short stretch of time.

Practical tips for keeping a reading habit going

To keep the habit going for a long time, it helps to let go of the pressure to finish the book. Instead of feeling you have to read the whole thing, switch your standard to simply filling the time you set for today, and it becomes much easier to keep up.

It’s also good to build the habit of jotting down even a short note about what you read. Including the process of reading a sentence, understanding it and summarizing it in your own words widens the range of the frontal lobe you use. It doesn’t need to be an elaborate reading journal; a line or two of thoughts is plenty.

Above all, just sitting in the same spot at the same time every day teaches the brain to recognize “now it’s time to focus.” It’s also worth remembering that simply fixing the place and time greatly shortens how long it takes for a habit to stick.

In the end, what matters is consistency

Terms like frontal lobe and aMCC may feel unfamiliar, but the core message is simple. If you repeat something slightly uncomfortable a little every day, the brain changes to match it. And as a starting point, few methods are as low-pressure and accessible as reading.

Rather than aiming to finish a thick book today, how about starting by reading for just 10 minutes without interruption? As those small repetitions add up, you may feel your focus change sooner than you expect.
