Want To Run Longer Or Lift More? Your Brain Might Be The Key

Brain Gains: Many people exercise purely for the physical benefits, like muscle growth and cardiovascular health. But a new study in Neuron shows that what’s driving endurance might actually be the brain.

The Study: Scientists watched brain activity in mice on treadmills, honing in on SF1 neurons in the ventromedial hypothalamus (a part of the brain involved in energy balance and metabolic response). These neurons fired while mice were running and stayed active for an hour after. Over weeks, SF1 signals grew stronger and more neurons activated each session. When researchers blocked SF1 neurons, mice lost stamina. But when they stimulated SF1 neurons post-workout, mice surpassed their natural plateau, which suggests brain activity after the workout is what drives fitness improvements.

The Takeaway: These results suggest your brain actively coordinates the metabolic and physiological shifts that make training stick. And it may be an explanation as to why consistency matters as much as intensity for building fitness.

Keep in Mind: This was a mouse study, so it doesn’t prove the same is true with humans. But it’s a compelling look at why your body gets better at exercise with consistency, and why the brain deserves more credit than it gets.

Is Your Retirement Plan Built to Last?

Planning for retirement means preparing for the unexpected: increased cash flow needs, heightened health care costs or a longer life than you might think. One key risk many retirees face is underestimating how long their savings need to last. Another is inflation, which can quietly reduce your purchasing power over time.

The 15-Minute Retirement Plan can help you navigate these challenges. With this guide, you can learn ways to account for a longer time horizon and manage the effects of inflation. If you have $1,000,000 or more saved, download your free guide to start building a more resilient financial future.

How Many Times Can You Actually Reheat Leftovers?

You Should Know: You likely grew up being told you could only reheat leftovers once. But is that really true? Well, food scientists have thoughts: they largely agree that multiple reheatings aren't inherently dangerous, as long as you handle food correctly at every step. What actually matters is how long food spends in the temperature “danger zone,” which falls between 40°F and 140°F.

Going Deeper: Reheating kills most active bacteria, but it can't touch the heat-resistant toxins some bacteria leave behind. Certain strains found in rice and meat-based dishes produce toxins that survive even a thorough reheat. And each time food cools back down after being heated, it re-enters that danger zone, which compounds the risk over time.

Takeaway: The smarter move is to portion out only what you're actually eating rather than heating the whole container. Get leftovers into the fridge within two hours of cooking, and make sure they reach 165°F all the way through when you reheat. If something smells off or looks wrong, trust that instinct.

Bottom Line: Reheating food more than once won't automatically make you sick, but it doesn’t remove all danger, either. But you’ll probably be fine if you handle it right.

SPOTLIGHT

Doing Away With Limits

JIM KWIK
Brain Coach, Author

Kindergarten is the time when most children are just learning how to read. But at that age, Jim Kwik suffered a traumatic brain injury that made reading, concentration, and other learning especially challenging. He taught himself how to read and write with the help of comic books, eventually becoming adept at speed-reading. As a result, Kwik became driven to unlock the secrets of learning and information retention in order to move from “feeling disempowered to feeling limitless.”

For more than 25 years, Kwik has built a career coaching top executives, actors, athletes, and entrepreneurs in his methods of communication, memory-building, information-processing, focus, and, yes, speed-reading (our staff is actually catching him speak live here this week). In his 2020 book, aptly titled Limitless, he brought these science-backed techniques to the masses so we all can push our own brains beyond our perceived limits.

In the book, Kwik focuses on “3 M’s” that can switch on our brains’ superpowers: mindset, motivation, and method. Flipping our mindset forces us to challenge self-imposed limited thinking and assumptions about what we can do. Identifying our passion and purpose ignites our motivation. Lastly, mastering Kwik’s method is intended to help us learn better, retain more, and master new skills — all with ease and speed.

Japanese Egg Rice

Serves: 1 | Cook Time: 10 minutes

This classic Japanese comfort food keeps things simple, letting texture take the lead. Hot rice is folded into vigorously whisked egg, which incorporates air and creates a light, custard-like texture. Soy sauce and furikake hit that rich umami flavor, and the result is a warm, silky, and satisfying dish that comes together almost instantly. It works equally well as a savory breakfast or an easy midnight snack.

HEALTHY HABIT

Desk Posture Check

Three times a day, do a quick posture scan. Are your shoulders creeping up toward your ears? Is your chin drifting forward? Reset by relaxing your shoulders and lengthening your spine. A few seconds of awareness can prevent hours of tension.
