Midlife, typically defined as ages 40 to 60, is an inflection point. It’s a time when our past behaviors begin to catch up with us and we start to notice our bodies and minds aging — sometimes in frustrating or disconcerting ways. But it’s also an opportunity: What our older years will look and feel […] More
The company said it will work to remove content about drugs like Ozempic, extended fasting and more from the “For You” feed.Emma Lembke did not know what an algorithm was when she started using social media.The then-12-year-old was thrilled when her parents gave her permission to join Instagram. She quickly followed all kinds of accounts — from Kim Kardashian to Olive Garden, she said — and was soon spending five to six hours a day on the app. Then one day she searched for “ab workouts,” and her feed shifted. She started seeing 200-calorie recipes, pro-anorexia posts and exercise routines that “no 12-year-old should be doing in their bedroom,” she said.Ms. Lembke, now 21, testified before the Senate Judiciary Committee in February 2023 about how social media led her to disordered eating, and what she and other advocates see as a dire need for stronger regulation to protect social media’s youngest users.Social media platforms have promised to take more action. On Friday, TikTok enacted what some experts called one of the most well-defined policies by a social media company yet on weight and dieting posts. The company’s updated guidelines, which come as TikTok faces a potential ban in the United States, include new guardrails on posts that show “potentially harmful weight management behaviors” and excessive exercise.TikTok said it will work to ensure the “For You” page, which serves as the main content feed on TikTok and is driven by an algorithm that caters to a user’s interests, no longer shows videos that promote “extended intermittent fasting,” exercises designed for “rapid and significant weight loss” or medications or supplements that promote muscle gain. The new regulations also aim to crack down on posts from influencers and other users promoting products used for weight loss or to suppress appetite, such as drugs like Ozempic. They also aim to curb content promoting anabolic steroid use.Under the new policy, machine learning models will attempt to flag and remove content that is considered potentially dangerous; a human moderation team will then review those posts to see if they need to remain off the For You feed, should be removed from age-restricted feeds or should be removed from the platform altogether, said Tara Wadhwa, TikTok’s director of policy in the United States.The elimination of problematic TikToks from the main feed is meant in part to “interrupt repetitive content patterns,” the new guidelines said. Ms. Wadhwa said the company wants to ensure users aren’t exposed to diet and weight loss content “in sequential order, or repeatedly over and over again.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

I fell in love with the Louvre one morning while doing disco moves to Michael Jackson’s “Don’t Stop ’Til You Get Enough” in the Salle des Cariatides.The museum, a former medieval fortress and then royal palace, had not yet opened, and I was following instructions to catwalk and hip bump and point in the grand room where Louis XIV once held plays and balls.The sun cast warm light through long windows, striping the pink-and-white checkered floor and bathing the marble arms, heads and wings of the ancient Grecian statues around me.“Point, and point, and point,” shouted Salim Bagayoko, a dance instructor. So I struck my best John Travolta poses and pointed around the room, my eyes landing on the delicate sandaled foot of Artemus, the wings of a Niobid and the stone penis of Apollo.The woman beside me caught my eye. We giggled.Over the years, I have felt many things in the world’s most-visited, and arguably most-famous, museum — irritation, exhaustion and some wonder, too.This time, I felt joy.The classes are part of an effort by museums and galleries across France to put on Olympics-themed shows as Paris prepares to host the Olympic Games.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

Barry McCarthy took over as C.E.O. in February 2022 to revive Peloton from its late-pandemic slump, but the company has struggled to become profitable.Peloton said on Thursday that its chief executive, Barry McCarthy, was stepping down and it would lay off more workers, as it continued to struggle in the fitness market.The connected-fitness company announced disappointing quarterly earnings on Thursday, with revenue down 4 percent from last year. The company, which has not turned a profit since December 2020, is also looking to refinance more than $1 billion in debt.Peloton had a spectacular rise at the start of the pandemic, when gyms and fitness centers closed and consumers were hungry for at-home workout options. But after gyms reopened, Peloton began to face stiffer competition from companies like Bowflex and Lululemon.Barry McCarthy, a former Spotify and Netflix executive, joined Peloton in 2022.Kevin Dietsch/Getty ImagesIt is reducing its head count by 15 percent, or 400 workers, in an effort to cut its costs this year by $200 million. Peloton has had several other rounds of job cuts in the past couple of years, most recently in October 2022, when it laid off about 12 percent of employees, or about 500 people.“Hard as the decision has been to make additional head count cuts, Peloton simply had no other way to bring its spending in line with its revenue,” Mr. McCarthy said in a statement.Investors appeared optimistic about the news; Peloton’s stock price rose about 9 percent in premarket trading.The company said it was looking to reduce its retail footprint and instead invest in “software, hardware and content portfolio and in improvements” for paying subscribers. Mr. McCarthy, a former Spotify and Netflix executive, joined Peloton in February 2022, taking over from the company’s founder, John Foley. Two board members, Karen Boone and Chris Bruzzo, will serve as interim co-chief executives. More
Research shows they can indeed deliver fitness benefits while you work — but only if you use them wisely.Experts have long known that extended inactivity can be bad for your body, increasing your risk for heart disease, Type 2 diabetes and other illnesses. As the saying goes, “sitting is the new smoking.” At the same time, decades of studies have shown that walking — even just 4,000 steps a day — is good for the mind and body.Treadmill desks — a setup involving a standing desk with a treadmill beneath it — seem like an ingenious antidote to sedentary office life, and a way to get in a few more healthy steps. But are they worth the investment?As treadmill desks have become more mainstream, researchers have begun to ask how effective they are. A growing body of studies, though often limited, suggests they do help keep people moving, adding perhaps an average of two extra miles of walking per day.What’s more, one small 2023 study suggested regular use of treadmill desks increased peoples’ energy, improved their moods and, in some cases, even made them more productive at their jobs.“Having the ability to add in little bits of activity over the course of a day can add up,” said Akinkunle Oye-Somefun, a doctoral candidate at York University in Toronto and the lead author of a recent meta-analysis of treadmill-desk research. However, he noted, “walking on a treadmill desk is an add on, not something meant to replace your regular exercise routine.”The key to getting the most health benefits out of a treadmill desk, and avoiding boredom or frustration, is to go in with the right expectations and strategy.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

VO2 max has become ubiquitous in fitness circles. But what does it measure and how important is it to know yours?Fitness is full of numbers meant to help you become faster and stronger. There’s your mile run time, your resting heart rate and measures of strength and flexibility. But perhaps the gold standard is VO2 max.A handful of years ago, the test — which tracks how much oxygen your body absorbs — was an obscure tool mainly used by elite athletes. Today, it’s touted by fitness professionals and wellness experts like Peter Attia as being a useful measure for all exercisers.But getting an accurate number requires an expensive and exhausting lab evaluation. And estimates provided by wearable devices might not tell you much. So how useful is it to invest time and money in the full work-up, and how important is knowing your VO2 max?For everyday people who want to be healthy and live a long time, the measurement is “the best piece of empirical information we have on health and longevity,” said Kate Baird, a clinical exercise physiologist and the coordinator of running and metabolic services at Hospital for Special Surgery in New York.The key, she said, is acting on what the data tells you.What is VO2 Max?“VO2 max” is a two-digit number that expresses how effectively your body metabolizes oxygen. The measurement itself is the milliliters of oxygen consumed in a minute per kilogram of body weight.As you exercise, your body needs ever more oxygen. The more you can efficiently consume, the more energy your muscles will have, increasing the time and intensity you can exercise. Generally speaking, someone with a higher VO2 max will be able to sustain a run or an aerobic activity at a given pace longer than someone with a lower VO2 max.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

The rock star’s viral social media post showed him doing a furious three-in-one routine, with weights. Gym professionals had thoughts.Regardless of what Us Weekly says, celebrities are not just like us.One had only to see the workout video Lenny Kravitz posted on Tuesday to know that.Thank God for today! Grateful. Never been better. There are no shortcuts so seize your day. It is all possible. Love! pic.twitter.com/BHqQ63oNOt— Lenny Kravitz (@LennyKravitz) April 9, 2024
First, there was Mr. Kravitz’s outfit: a plum-colored muscle tank, complete with leather pants, black boots and his signature sunglasses.Then there was the exercise itself, which took place on a decline bench and involved a barbell with weights on each side.At the starting position, Mr. Kravitz is supine, with the bar extended below his head. Then, while hoisting the upward with a furious motion, he appears to do a combination of a pullover and a situp. At the upright position, he does a shoulder press, bringing the bar over his head.In the video, Mr. Kravitz, 59, performs seven reps before handing the weight off to a trainer, who, in his wraparound shades, bears a resemblance to Joe Manganiello, Channing Tatum’s hulking sidekick in “Magic Mike.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

Some exercisers say cannabis eases their pain and anxiety — and makes fitness more fun.The first time Samantha O’Brien took a boxing class at her building’s gym, she was overwhelmed with anxiety. The instructor was loud and intimidating and ran the class like a boot camp. If someone fell behind, everyone had to work harder.Ms. O’Brien, 36, left the class thinking she’d never return. A few days later, her partner came home with some cannabis gummies he said might offer her a burst of energy. She thought of the boxing class, and how she wanted to show the instructor he hadn’t scared her off. So she ate half a gummy, got into her workout clothes and went to the class.The shouting didn’t bother her anymore. “I was brighter, lighter,” Ms. O’Brien said, adding that the small dose kept her going through the session. Now she frequently mixes cannabis and exercise, regularly attending the boxing class along with Pilates and boot camp workouts after taking weed products.Scientists have refuted the idea that marijuana is a performance enhancer for competitive athletes. But some amateurs are turning to it before exercise because it eases their chronic pain and anxiety — or just because it makes working out more fun.Alex Friedrichs, 30, a manager of a chiropractic clinic in Vancouver, Canada, said that cannabis puts her in the moment during exercise. “I appreciate what my body is capable of, what my body is doing and the things I’m seeing around me,” she explained, “like running in a beautiful area or a pretty day.”Addressing Chronic PainIn a small 2019 study, the top reasons people used cannabis before exercise were to increase enjoyment and focus. But close behind was pain relief. Research has shown that marijuana can help some patients alleviate chronic pain, which affects some one in five people around the world. When the pain is treated, people become more functional, said Dr. Alan Bell, a physician and assistant professor at the University of Toronto who was the lead author on a set of clinical practice guidelines for using cannabis to treat chronic pain.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
