After a tough workout, your body enters a state of stress: muscle fibers are damaged, energy stores are depleted, and hydration levels drop. This is a critical moment. If your body gets the right nutrients, it starts rebuilding immediately. If not, recovery slows down, and so does progress.

Tyburski was a professional adventurer, financing his pursuits via magazine articles and speaking gigs, and even making a documentary about his quest. His whole raison d'etre was to push past his limitations, showing what a person is capable of when their mindset is strong enough.

It's the most ubiquitous, effective, totally no-side-effects drug in the world. Exercise is also something Metzl feels is sometimes overlooked in the longevity space, in favor of fancier products. A lot of this stuff we talk about with longevity is not validated, like full-body MRIs and these supplement stacks.

Cross training and running go together like peanut butter and jelly. If you build it into your schedule intentionally, strategically, and with a clear understanding of what you're trying to accomplish, you'll thrive. Megan makes the case that cross-training serves runners for several distinct reasons, and the right reason for you will shape how you approach it.

Because we're homeotherms, we assume all mammals work the way we do. But in recent years, as improvements in technology allowed researchers to more easily track small animals and their metabolisms in the wild, we're starting to find a lot more weirdness.

In 2018, Sharples and his research lab, now at the Norwegian School of Sport Sciences in Oslo, were the first to show that exercise could change how our muscle-building genes work over the long term. The genes themselves don't change, but repeated periods of exertion turns certain genes on, spurring cells to build muscle mass more quickly than before. These epigenetic changes have a lasting effect: Your muscles remember these periods of strength and respond favorably in the future.

"I can't tell you how many times I've had patients who have had so much trouble losing weight complain to me that their friends can eat whatever they want and never put weight on," Perlman, an integrative and functional medicine doctor and former chief medical officer for Mayo Clinic's integrative medicine program, told Business Insider. It's also one of the biggest misconceptions he hears about metabolic health.

Even before the first set and first hour of his match elapsed, Tomas Machac had asked the umpire for the tournament doctor, trainer and pickle juice, the drink du jour for tackling cramps. Those preventive measures taken in the intense early stages of his third-round tussle with Lorenzo Musetti proved to be sensible, for the pair would spend a brutal four hours, 25 minutes on court.

There's a glorious smugness that can only be experienced by exercising outdoors in winter conditions. The fresh air, the endorphins, the reduced risk of heart disease they're all nice bonuses, but nothing beats that knowing nod from another rain-drenched runner, or the horrified faces of nearby dog walkers as you stride confidently into the sea for a winter dip.
