Arnold Schwarzenegger fueled a lot of the interest in strength training, beginning in the 1980s

Modern bodybuilding evolved in the 19th century

The origins of modern progressive resistance exercise are traced to ancient Greece, where a repeat Olympic victor carried a calf every day until it grew into a full-sized ox. This 56-minute comedy and history podcast journeys through the rise of modern bodybuilding, which took off during the 19th century.

The Greeks weightlifted using massive stones—but viewed muscles differently

Ancient Greek art is replete with humans with muscular physiques, but there is very little evidence they knew much about proper weightlifting. There are just a few stones with inscriptions hinting at their weightlifting use. This article exposes some of our modern assumptions about muscle development, suggesting the Greeks thought differently about strength than we do today.

How to safely start 'Strengthmaxxing' with body weight—not actual weights

Beginning with exercises like a pull-up, for example, a weight training beginner can start in a "dead hang" with arms straight while grasping the bar and with feet off the ground. Then, lift your eyes to bar height before dropping again without any bouncing. Exercisers should feel like they've reached "failure" before they're done—meaning they feel like they could only do a couple more of the exercise if it was a life-or-death situation.

Strength training appears to make for a healthier, youthful-looking brain

A study from 2025 links having higher amounts of muscle with a more youthful-looking brain age. Scientists analyzed data from more than 1,100 healthy adults around their mid-50s after they underwent full-body MRIs, comparing muscle, fat, and brain age appearances from the scans.Their findings link strength training and controlling visceral fat with improved brain health. The research didn't tease apart why this benefit occurs.

Bill Bowerman brought running for fitness to America

Nike cofounder Bill Bowerman once cowrote a book with a doctor, W.E. Harris, called “Jogging.” Published in 1967 by New York, Grosset & Dunlap, it introduced America to the idea of running for health, instead of just sport—and kicked off the fitness frenzy of the 1970s that fueled Nike’s early success.

Health food broke into the mainstream by the 1980s

A 1984 New York Times story noted that Americans were eating less red meat than a decade prior, and that, in general, the country was “talking, thinking and worrying about what they eat to a degree unique in the nation's history.” The feature then details foods that were then considered bizarre: whole-grain muffins, hummus, and a variety of vegetarian dishes.

Microtears in muscles from exercise cause fibers to grow back larger

Placing muscle under increased load or stress causes damage that requires rest to repair, leading to stronger, more enduring muscle over time. Muscles adapt to such increasing demands by improving their efficiency with approaches that include increasing the number of mitochondria housed in hundreds of thousands of muscle cells.

Pilates was invented by an acrobatic WWI prisoner of war

As the Great War raged on, and as months gave way to years, the imprisoned Joseph Pilates explored a question that he had pondered since childhood: Could he reimagine the capabilities of the human body through an anatomically based method of training, taking inspiration from scientific treatises, the carefree movement of children, and the dexterous ease of cats? Read this article to learn about the birth and legacy of Pilates.

The fitness industry has seen a lot of fads—and Peloton might be one of them

Richard Hittleman brought yoga to TV

"Yoga For Health" was a 1960s television show that sought to make yoga accessible for everyday Americans. Richard Hittleman, the show's host, walked viewers through basic postures, introducing them to the practice's therapeutic benefits. "We know that within us there's great forces, and great power, and great beauty," he says in this 1961 episode, "and the idea is to bring it out."

Doctors are prescribing social activities—and seeing good results

Physicians, especially in the UK, are asking patients what they enjoy and then prescribing a consistent regimen of doing that type of activity to improve fitness and overall health, including community exercise classes, volunteering, and spending time in nature. This approach may provide better incentives to stick with an activity.

Hysterical strength allows someone to lift a car off their child

When the body responds to an acute crisis—say a family member trapped under a car—people can sometimes perform seemingly superhuman feats. This is more than an urban legend: In 2012, a 22 year-old-woman lifted a vehicle off her father, and seven years earlier another man lifted a vehicle off a trapped cyclist. Yet scientists are still unraveling details about why this can occur.

How Chuck Norris 'Facts' gave birth to the modern meme

In the early 2000s, anonymous, absurdly hyperbolic jokes about one B-level action star suddenly appeared everywhere on the internet. "Chuck Norris Facts" were spawned by a high school senior, who'd noticed something funny online and taken it to the next level. As Ryan Hockensmith shows in this detailed history, Spector's joke laid the groundwork for the modern meme.

Retired gladiators often became trainers, referees, or exhibition fighters

Few gladiators survived to retirement, but those who did rarely left the arena behind. Many returned for high-pay exhibition bouts, trained new fighters, served as referees, or leveraged their fame into unexpected careers, including local politics.

Some athletes warm up with equipment from other sports

Baseball superstar Shohei Ohtani uses a cricket bat; his teammate Yoshinobu Yamamoto throws a javelin. Quarterback CJ Stroud shoots free throws. The reasons are partially physical (it's good to exercise different parts of your body) and partially mental (it's nice to take the pressure off with someone else's game).

High fuel prices and fuel shortages revived dormant interest in EVs

Electric vehicles, in the form of motorized carriages, predate the invention of the gas-powered automobile by over 40 years. The latter's affordability made it more popular until technological advances made EVs more viable to consumers in the early 2000s.

Read a deep dive on the 'all-purpose healing' peptide BPC-157.

Peptides like BPC-157 are marketed based largely on animal studies, not human research

BPC-157, which purportedly helps with tissue repair and muscle growth, can cause concerning side effects, including pain and swelling. TB-500, another experimental peptide, is marketed for wound healing, but it hasn't undergone any clinical human trials, and high levels of this peptide have been linked to tumor growth.

Within months of a landmark 2002 study that indicated HRT harms, sales dropped by about half

In the early 2000s, Women's Health Initiative studies indicated HRT increased risk of breast cancer, heart disease, and stroke in some women—so many physicians stopped prescribing it to help with menopause symptoms. But further research has concluded that much of the elevated risk was overblown and that it was also disproportionately seen in women in their 70s who had been taking an older HRT formulation.

Diving boards disappeared out of safety, but they don't cause most diving accidents

Bouncy diving boards were widely adopted in backyard and community pools in the 1960s. Reports identifying diving as the primary cause of sports-related spinal accidents exaggerated the role diving boards played (most diving injuries were in lakes, beaches, and rivers) and gave insurers a basis to reduce coverage.
