How a 'light bulb moment' in an Arkansas barn made Ryan Crouser a shot put juggernaut

It sounds like the plot to a cheesy black-and-white movie from the 1940s.

A lunk of a guy goes out to the barn behind his house every night and tosses a metal ball as far as he can. Over and over. He tries shifting his feet, turning his body in different directions, tinkering.

And, just like that, he revolutionizes the sport of shot put.

But this isn’t a Hollywood story. Ryan Crouser used his innovative “Crouser Slide” to make history at the 2024 Paris Olympics this weekend, joining a select group of athletes who have dominated their event thoroughly enough to win gold at three consecutive Games.

The 31-year-old native of Boring, Ore., called it “kind of a testament to the total dedication and hard work that has gone into it … it’s a 365-day a year job.”

With all the superstars competing here in the last few days — gymnast Simone Biles, swimmer Katie Ledecky, sprinter Noah Lyles — it might be easy to overlook Crouser. It would also be a mistake.

His story exemplifies the best aspect of the Olympics: The range of obscure and semi-obscure sports filled with athletes who devote their lives to something with no guarantee of fortune or fame.

To fully appreciate what Crouser accomplished, it helps to know more about the shot put.

The only way to heave a 16-pound ball more than 70 feet is to generate momentum by spinning your way to the release, which can be especially tricky for very large people trapped inside a seven-foot ring.

So it makes sense that, despite all their girth and grunting, shot putters tend to be science geeks.

Rather than focus on brute force, they obsess over the physics of lateral velocity, rotational radius and acceleration paths. The biomechanically optimal angle of release — 36 degrees? 38 degrees? — can be a topic for debate.

“So it’s constantly changing and evolving,” Crouser says. “Kind of under the assumption of how do we maximize potential energy creation while minimizing room for error.”

Throwing runs in his blood. His father, Mitch, was an alternate on the 1984 U.S. Olympic discus team and uncle Brian threw javelin at two Games. After excelling at shot put in high school, Crouser won four NCAA championships for the University of Texas.

His first gold at the 2016 Rio de Janeiro Games came shortly after graduation.

In a sport where many top athletes stand about 6 feet tall, Crouser uses his 6-foot-7 frame for more leverage and force on throws. But height also makes him vulnerable to committing a foul by stepping outside of that claustrophobic ring.

In his early years at the international level, he employed a fairly standard technique, working to control his body by moving precisely. In 2021, he broke Randy Barnes’ 31-year-old record with a throw of more than 76 feet at the U.S. Olympic trials, then won his second gold at the Tokyo Games.

Still, he wasn’t content.

“I feel like I experimented for a number of years just with different techniques,” he recalls. “I try to think of a rational explanation for why it would help my throw and then I’ll implement it.”

The “Fosbury Flop,” the back-roll technique made famous by Dick Fosbury at the 1968 Summer Olympics, forever changing the high jump, ranks as track’s best-known stylistic breakthrough. Though subtler, the “Crouser Slide” has been revolutionary.

Restless for something better, the self-coached Crouser searched the internet for information and applied concepts from upper-level engineering courses he took in college before switching his major to economics.

All his tinkering, spread across thousands of practice throws, led to a “light bulb moment” in that Arkansas barn in December 2022. It was about 8 p.m. and he recalls thinking “Yeah, let’s try something new just to engage myself because shot put can be extremely monotonous.”

He focused on altering the conventional starting point, which has shot putters standing at the back of the ring, facing away from the field. Crouser shifted over to the right side of the circle, creating room to his left.

The adjustment allowed him to start his motion with a quick “slide step” to the left. It made his spin a little faster and gave his right leg more space to swing around. As he explained: “Speed is king in the shot put.”

Speed can also be unwieldy, so there were problems with consistency. But within a few months, at a springtime meet in Los Angeles, he became the first man to throw beyond 77 feet.

“It’s good for the sport,” rival Tom Walsh told reporters in his home country of New Zealand. “But we’ve got to keep our end of the bar up and keep pushing him, keep challenging him, because when someone is too dominant, the sport gets a bit dull.”

During the past 10 or so years, Crouser has amassed five of the top six — and 14 of the top 25 — throws ever.

As important as technique and mental approach can be, the shot put remains — at its core — physical and brutal.

“Throwing a 16-pound ball for a living beats you up,” Crouser said.

Doctors found two blood clots in his leg last summer. Cleared to fly at the last moment, he traveled to Budapest to defend his world championship.

Since then, a torn pectoral muscle and nagging elbow injury have forced him to adjust his practice routine. Sometimes he throws hard and takes a few days off, other times he strings together light workouts.

“I have had a bit of difficulty recognizing that I am getting older,” he says. “It makes me cherish this Olympic experience even more because I can see that I cannot do this forever.”

2024 Paris Summer Olympic Games

Heading into Saturday night’s final in Paris, it wasn’t clear if the elbow could hold up for six rounds. Rather than build his distances gradually, Crouser chased big throws early — a gamble — hoping his opponents might tighten up if they fell behind.

Throwing 74 feet 3 inches on his first attempt, he raised his arms and worked the crowd. His lead had widened by the third round, at which point nature intervened.

A storm blew in, drenching the stadium and making the shot put ring treacherously slippery. One after another, competitors started attempts only to have their feet slip and their throws fall harmlessly. U.S. teammate and longtime rival Joe Kovacs unleashed a gutty try in the final round but, for a third consecutive Olympics, finished with silver.

Speaking in the mixed zone, Crouser reflected on years of eating right, getting nine hours of sleep each night and forgoing alcohol except for a 10-day vacation at the end of each track season. He mused about winning a fourth gold at the 2028 Summer Games in Los Angeles.

If his body lasts. If he can keep thinking up improvements for his technique.

A reporter asked him about a moment from earlier in the evening. Before the finals, the shot putters emerged from a tunnel, one by one, pausing in front of a television camera. Crouser dropped to one knee in an homage to French sculpture.

His pose? The Thinker.

Very little plastic being recycled in California as state efforts falter

Very little plastic being recycled in California as state efforts falter

California touts itself as a leader on the problem of plastic garbage, but recent developments suggest otherwise.

A new report issued by the state’s waste agency shows plastic yogurt containers, shampoo bottles and restaurant takeout trays are being recycled at rates only in the single digits.

Polypropylene, labeled as #5 on packaging, is used for yogurt containers, margarine tubs and microwavable trays. Only 2% of it is getting recycled. Colored shampoo and detergent bottles, made from polyethylene, or #1 plastic, are getting recycled at a rate of just 5%.

Other plastics, including ones promoted as highly recyclable, such as clear polyethylene bottles, which hold some medications, or hard water bottles, are being recycled at just 16%.

No plastic in the report exceeds a recycling rate of 23%, with the majority reported in just the single digits.

Adding to this disquieting assessment, CalRecycle also just pulled back regulations that were supposed to finalize a landmark single-use plastic law known as Senate Bill 54 — a law designed to make the majority of packaging waste in the state recyclable or compostable by working with the plastic and packaging industries.

The report and delay have sparked a wide variety of reactions by those who have closely watched the law as it was written and implemented.

The proposed regulations were regarded as friendly to industry. As a result, some are hopeful that CalRecycle’s decision to pull them back for tweaking means the agency will make the law stronger. Others say the two developments just show the state has never really been serious about plastic recycling.

“California’s SB 54 … will NEVER increase the recycling rates of these items … because cartons and plastic packaging are fundamentally not technically or economically recyclable,” said Jan Dell, the founder of Orange County-based Last Beach Cleanup, an anti-plastic organization.

Industry representatives are also expressing disappointment, saying the more delays and changes the state makes, the harder it is “for California businesses to comply with the law and implement the resulting changes,” said John Myers, a spokesman for the California Chamber of Commerce, which represents companies that will be affected.

Reports on abysmally low rates of recycling for milk cartons and polystyrene have been widely shared and known. But the newest numbers were still a grim confirmation that there are few options for dealing with these materials.

According to one state analysis, 2.9 million tons of single-use plastic and 171.4 billion single-use plastic components were sold, offered for sale or distributed in California in 2023.

Single-use plastics and plastic waste more broadly are considered a growing environmental and health problem. In recent decades, plastic waste has overwhelmed waterways and oceans, sickening marine life and threatening human health.

Last spring, the Newsom administration was accused of neutering the regulations that CalRecycle had initially proposed to implement the law. The changes excluded all packaging material related to produce, meat, dairy products, dog food, toothpaste, condoms, shampoo and cereal boxes, among other products. These are all products that might fall under the purview of the U.S. Food and Drug Administration and the U.S. Department of Agriculture.

It also opened the door to “alternative” recycling, such as chemical recycling, which environmentalists say is polluting, and was banned in the language of the law.

The waste agency then submitted those draft regulations to the Office of Administrative Law, whose lawyers and staff review proposed regulations to ensure they are “clear, necessary, legally valid, and available to the public” before finalizing them. They were set to release their determination on Friday; CalRecycle pulled the regulations back before the office issued its determination.

Neither the law office nor governor’s office responded to requests for comment.

Melanie Turner, CalRecycle’s spokeswoman, said the agency withdrew its proposed regulations “to make changes … to improve clarity and support successful implementation of the law,” and its revisions were focused on areas that dealt with “food and agricultural commodities.”

California State Sen. Ben Allen (D-Santa Monica), author of the original legislation, called the delay “entirely avoidable” in a statement, but said it would allow CalRecycle an “opportunity to ensure the regulations truly follow the law as it was signed.”

He urged the waste agency and Newsom’s administration not to “allow broad, sweeping exemptions that would undermine the program and increase costs for ratepayers.”

Critics of the watered-down regulations, such as Anja Brandon, the director of plastics policy for the Ocean Conservancy, said she wasn’t surprised by the withdrawal.

The proposed regulations “would have gone beyond CalRecycle’s authority by creating a sweeping categorical exclusion for food and agricultural packaging — effectively a loophole that would have allowed producers to continue putting vast amounts of plastic packaging into the marketplace, completely undermining SB 54’s goals and success,” she said in a text message.

Turner said CalRecycle will conduct a 15-day comment period — although when that begins has not yet been divulged.

Cancer survival rates soar nationwide, but L.A. doctors warn cultural and educational barriers leave some behind

Cancer survival rates soar nationwide, but L.A. doctors warn cultural and educational barriers leave some behind

The American Cancer Society’s 2026 Cancer Statistics report, released Tuesday, marks a major milestone for U.S. cancer survival rates. For the first time, the annual report shows that 70% of Americans diagnosed with cancer can expect to live at least five years, compared with just 49% in the mid-1970s.

The new findings, based on data from national cancer records and death statistics from 2015 to 2021, also show promising progress in survival rates for people with the deadliest, most advanced and hardest-to-treat cancers when compared with rates from the mid-1990s. The five-year survival rate for myeloma, for example, nearly doubled (from 32% to 62%). The survival rate for liver cancer tripled (from 7% to 22%), for late-stage lung cancer nearly doubled (from 20% to 37%), and for both melanoma and rectal cancer more than doubled (from 16% to 35% and from 8% to 18%, respectively).

For all cancers, the five-year survival rate more than doubled since the mid-1990s, rising from 17% to 35%.

This also signals a 34% drop in cancer mortality since 1991, translating to an estimated 4.8 million fewer cancer deaths between 1991 and 2023. These significant public health advances result from years of public investment in research, early detection and prevention, and improved cancer treatment, according to the report.

“This stunning victory is largely the result of decades of cancer research that provided clinicians with the tools to treat the disease more effectively, turning many cancers from a death sentence into a chronic disease,” said Rebecca Siegel, senior scientific director at the American Cancer Society and lead author of the report.

As more people survive cancer, there is also a growing focus on the quality of life after treatment. Patients, families and caregivers face physical, financial and emotional challenges. Dr. William Dahut, the American Cancer Society’s chief scientific officer, said that ongoing innovation must go hand in hand with better support services and policies, so all survivors — not just the privileged — can have “not only more days, but better days.”

Indeed, the report also shows that not everyone has benefited equally from the advances of the last few decades. American Indian and Alaska Native people now have the highest cancer death rates in the country, with deaths from kidney, liver, stomach and cervical cancers about double that of white Americans.

Additionally, Black women are more likely to die from breast and uterine cancers than non-Black women — and Black men have the highest cancer rates of any American demographic. The report connects these disparities in survival to long-standing issues such as income inequity and the effects of past discrimination, such as redlining, affecting where people live — forcing historically marginalized populations to be disproportionately exposed to environmental carcinogens.

Dr. René Javier Sotelo, a urologic oncologist at Keck Medicine of USC, notes that the fight against cancer in Southern California, amid long-standing disparities facing vulnerable communities, is very much about overcoming educational, cultural and socioeconomic barriers.

While access to care and insurance options in Los Angeles are relatively robust, many disparities persist because community members often lack crucial information about risk factors, screening and early warning signs. “We need to insist on the importance of education and screening,” Sotelo said. He emphasized that making resources, helplines and culturally tailored materials readily available to everyone is crucial.

He cites penile cancer as a stark example: rates are higher among Latino men in L.A., not necessarily due to lack of access, but because of gaps in awareness and education around HPV vaccination and hygiene.

Despite these persisting inequities, the dramatic nationwide improvement in cancer survival is unquestionably good news, bringing renewed hope to many individuals and families. However, the report also gives a clear warning: Proposed federal cuts to cancer research and health insurance could stop or even undo these important gains.

“We can’t stop now,” warned Shane Jacobson, the American Cancer Society’s chief executive.

“We need to understand that we are not yet there,” Sotelo concurred. ”Cancer is still an issue.”

Clashing with the state, L.A. City moves to adopt lenient wildfire ‘Zone Zero’ regulations

Clashing with the state, L.A. City moves to adopt lenient wildfire ‘Zone Zero’ regulations

As the state continues multiyear marathon discussions on rules for what residents in wildfire hazard zones must do to make the first five feet from their houses — an area dubbed “Zone Zero” — ember-resistant, the Los Angeles City Council voted Tuesday to start creating its own version of the regulations that is more lenient than most proposals currently favored in Sacramento.

Critics of Zone Zero, who are worried about the financial burden and labor required to comply as well as the detrimental impacts to urban ecosystems, have been particularly vocal in Los Angeles. However, wildfire safety advocates worry the measures endorsed by L.A.’s City Council will do little to prevent homes from burning.

“My motion is to get advice from local experts, from the Fire Department, to actually put something in place that makes sense, that’s rooted in science,” said City Councilmember John Lee, who put forth the motion. “Sacramento, unfortunately, doesn’t consult with the largest city in the state — the largest area that deals with wildfires — and so, this is our way of sending a message.”

Tony Andersen — executive officer of the state’s Board of Forestry and Fire Protection, which is in charge of creating the regulations — has repeatedly stressed the board’s commitment to incorporating L.A.’s feedback. Over the last year, the board hosted a contentious public meeting in Pasadena, walking tours with L.A. residents and numerous virtual workshops and hearings.

Some L.A. residents are championing a proposed fire-safety rule, referred to as “Zone Zero,” requiring the clearance of flammable material within the first five feet of homes. Others are skeptical of its value.

With the state long past its original Jan. 1, 2023, deadline to complete the regulations, several cities around the state have taken the matter into their own hands and adopted regulations ahead of the state, including Berkeley and San Diego.

“With the lack of guidance from the State Board of Forestry and Fire Protection, the City is left in a precarious position as it strives to protect residents, property, and the landscape that creates the City of Los Angeles,” the L.A. City Council motion states.

However, unlike San Diego and Berkeley, whose regulations more or less match the strictest options the state Board of Forestry is considering, Los Angeles is pushing for a more lenient approach.

The statewide regulations, once adopted, are expected to override any local versions that are significantly more lenient.

The Zone Zero regulations apply only to rural areas where the California Department of Forestry and Fire Protection responds to fires and urban areas that Cal Fire has determined have “very high” fire hazard. In L.A., that includes significant portions of Silver Lake, Echo Park, Brentwood and Pacific Palisades.

Fire experts and L.A. residents are generally fine with many of the measures within the state’s Zone Zero draft regulations, such as the requirement that there be no wooden or combustible fences or outbuildings within the first five feet of a home. Then there are some measures already required under previous wildfire regulations — such as removing dead vegetation like twigs and leaves, from the ground, roof and gutters — that are not under debate.

However, other new measures introduced by the state have generated controversy, especially in Los Angeles. The disputes have mainly centered around what to do about trees and other living vegetation, like shrubs and grass.

The state is considering two options for trees: One would require residents to trim branches within five feet of a house’s walls and roof; the other does not. Both require keeping trees well-maintained and at least 10 feet from chimneys.

On vegetation, the state is considering options for Zone Zero ranging from banning virtually all vegetation beyond small potted plants to just maintaining the regulations already on the books, which allow nearly all healthy vegetation.

Lee’s motion instructs the Los Angeles Fire Department to create regulations in line with the most lenient options that allow healthy vegetation and do not require the removal of tree limbs within five feet of a house. It is unclear whether LAFD will complete the process before the Board of Forestry considers finalized statewide regulations, which it expects to do midyear.

The motion follows a pointed report from LAFD and the city’s Community Forest Advisory Committee that argued the Board of Forestry’s draft regulations stepped beyond the intentions of the 2020 law creating Zone Zero, would undermine the city’s biodiversity goals and could result in the loss of up to 18% of the urban tree canopy in some neighborhoods.

The board has not decided which approach it will adopt statewide, but fire safety advocates worry that the lenient options championed by L.A. do little to protect vulnerable homes from wildfire.

Recent studies into fire mechanics have generally found that the intense heat from wildfire can quickly dry out these plants, making them susceptible to ignition from embers, flames and radiant heat. And anything next to a house that can burn risks taking the house with it.

Another recent study that looked at five major wildfires in California from the last decade, not including the 2025 Eaton and Palisades fires, found that 20% of homes with significant vegetation in Zone Zero survived, compared to 37% of homes that had cleared the vegetation.
