A simple timepiece and humanity's greatest adventure

A simple timepiece and humanity's greatest adventure

Yahoo21 hours ago
Behind a plate of glass, overshadowed by the conical capsule that brought three American astronauts home from the moon in 1969, a wristwatch rests on a small stand. The command module Columbia, part of the Apollo 11 rocket assembly that Neil Armstrong and Edwin 'Buzz' Aldrin rode to everlasting renown on the lunar surface, is still an intricate piece of space-age technology lined with buttons, lights, handles, hatches and an external coating of hexagon tiles, now faded a rusty orange. But the watch seems rather ordinary: white lines on a dark analog face, with a dark canvas Velcro strap.
It's an Omega Speedmaster Chronograph, to be exact. A classic pilot's watch, worn by the third member of that famous crew. Michael Collins never set foot on the moon; his job was to man the Columbia while the Eagle carried the others to the surface, miles below. But Collins' path of orbit took him as far from Earth as any human had ever been. Each time the module circled the far side of the moon, the radio went dark. He was cut off from his crewmates, from NASA's control center in Houston, from all humankind.
While his crewmates took a familiar 'giant leap' into history, Collins waited. They spent 21 hours, 36 minutes in the Sea of Tranquility, as he waited, alone. I can almost picture him peering through the window and holding his breath each time the Columbia emerged from the moon's shadow, relieved to find the sun still shining over our little blue planet, but waiting for some distant, reassuring voice to come over the radio waves. What was it like when somebody finally broke that infinite silence? 'I knew I was alone,' he observed later, 'in a way that no earthling has ever been before.'
That quote is immortalized on a placard near the watch, though Collins remains a supporting character in one of America's greatest stories. On my first visit to the National Air and Space Museum in Washington, D.C., I'm fascinated by a range of more spectacular exhibits, from the Wright brothers' first plane to Armstrong's moonwalk suit. But I keep coming back to the watch worn by 'the world's loneliest man.' I think about his quiet role in what we accomplished as a nation, working shoulder to shoulder for the common good, and I wonder if we'll ever do that again.
Generations of American kids have dreamed of becoming astronauts and exploring the cosmos. But few were bigger space nerds than my parents, both of them scientists. We lived in South Florida, so naturally, we traveled to the John F. Kennedy Space Center at Cape Canaveral almost every year. The nation's premier rocket launch facility covers 6,000 acres on the 'Space Coast,' about 40 miles east of Orlando, with plenty of room to store certain artifacts that just wouldn't work on the National Mall. Like the entire space shuttle Atlantis, which flew 33 missions between 1985 and 2011.
I remember stumbling backward when I tried to look up at the roof of the Vehicle Assembly Building, eighth-largest in the world by volume. It's so big, some have claimed that clouds can form inside (this is sadly not true). I remember the Astronaut Hall of Fame. I remember The Crawlers, tracked transports that could carry the weight of 20 fully loaded Boeing 777 jets. And I remember the Saturn V rocket that hangs from the roof of the Apollo Center — the kind that powered the moon missions, the most powerful ever built. Seeing it all made space feel real to me.
A small theater there tells the story of Apollo 11, from political initiative to technological innovation and the human characters who played it out. It tells of Armstrong, gliding over the lunar surface, looking for a spot to land where he and Aldrin wouldn't get stuck after he missed the original target. President Richard Nixon even had a speech prepared for that scenario. 'These two men are laying down their lives in mankind's most noble goal: the search for truth and understanding,' he would have said. 'In their exploration, they stirred the people of the world to feel as one; in their sacrifice, they bind more tightly the brotherhood of man.'
Thankfully, the speech wasn't needed, but the sentiment was real.
'Not since Adam has any human known such solitude.'
Humans have always felt an urge to explore, often at our own peril. Perhaps it began when we wondered what berries or game waited beyond that hill or across that river. Every mile we covered opened up a thousand more, over and over, for millennia. But what's left for us to find? When every inch of land is mapped, photographed, scanned with LiDAR and analyzed by artificial intelligence? No wonder Captain Kirk, in the 'Star Trek' TV and film series, calls space 'the final frontier.' Where I grew up, there was no hope of emulating Leif Erikson, Amelia Earhart or Meriwether Lewis. Space was all we had left.
And we ate it up. Look at most any streaming service, and you'll find a galaxy of space programming, from the romantic 'Star Wars' universe to gritty dramas like 'Interstellar.' But most of the genre misses the point. For their characters, space travel has been figured out, becoming about as rare as commuting to the office and about that risky, too. As viewers, we've come to accept space as a background, part of the scenery. But what made it so alluring to begin with was always the unknown, the danger and the selfless cooperation, sacrifice and mutual competition it took to get us off this planet to begin with.
The Communists started it. On October 4, 1957, amid ratcheting tensions in the Cold War, the Soviet Union launched an unmanned satellite called Sputnik into orbit. A month later, they sent up a stray dog drafted off the streets of Moscow — known as Laika — who died in Sputnik 2. These weren't PR stunts. Space travel called on advanced rocket technology that could also deliver nuclear missiles more effectively. The United States had to respond, joining the space race. In July 1958, President Dwight D. Eisenhower created NASA to 'carry out the peaceful and scientific parts of the space program,' per a display at the National Air and Space Museum.
But the U.S. was already far behind. The Soviets landed an unmanned spacecraft on the moon in 1959. In 1961, they made cosmonaut Yuri Gagarin the first human in orbit. NASA didn't even have rockets designed for space travel. Even so, three weeks later, they strapped a capsule to the top of an intercontinental ballistic missile, built to deliver a nuclear warhead. In its place, Alan Shepard crammed himself into a compartment the size of a refrigerator inside the Freedom 7 — also on display — and blasted off to replicate Gagarin's feat in May 1961.
It wasn't enough to stay neck-and-neck. That same month, President John F. Kennedy asked Congress for funding to land American astronauts on the moon by decade's end. Speaking at Rice University in 1962, he doubled down. 'We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard.' Watching these speeches on video at the museum, I feel the same awe and inspiration I did as a kid. The message worked on Congress, too. NASA's budget was increased fivefold by 1966. The cost of the Apollo program totaled about $25.8 billion — 10 times that in today's dollars.
650 million people watched Armstrong and Aldrin walk on the moon. Collins was nowhere to be seen.
Cash was just a start. Massive infrastructure centers were built in Houston and Cape Canaveral, where teams of scientists, mathematicians and intrepid pilots put in the work and took the risks. On January 27, 1967, three astronauts assigned to the Apollo 1 mission were killed during a simulated launch test, unable to escape after fire broke out in the command module. They were mourned on the cover of Time magazine, and the program's naming convention skipped to Apollo 4 in their honor. Even so, by late 1968, manned flights were inching closer to the moon every two to three months.
As the Apollo 11 crew prepared to make history, Life magazine photographer Ralph Morse was making them famous — and human. In his work, Armstrong plays baseball with a son and reads the paper over dinner, getting home too late to eat with his family. Aldrin keeps it professional, posing in a jumpsuit by a model of the moon. Collins rides bikes with his three kids, paints at home and reads paperbacks at a beach with his wife. These images — some published then, some decades later — bring home what these ordinary men were willing to risk for love of country and to see what was around the bend.
When Armstrong and Aldrin took their first steps on the moon, about 650 million people around the world watched on TV and heard Armstrong's iconic narration of a truly unique accomplishment. Collins, as we know, was nowhere to be seen. But an American flag was planted on the surface, a Cold War victory that the Soviets never matched. Back on Earth, they took a 38-day celebration tour, visiting 24 countries. As one display at the museum notes, 'people worldwide looked upon the first moon landing as a human achievement, not just an American one.'
If Morse made the astronauts celebrities, their journey made them heroes. 'People enjoy being amazed, and space exploration never fails to deliver,' writes Andrew Chaikin via email. The author has largely dedicated his career to chronicling the Apollo era. It's not just about discovery. Unmanned missions and space telescopes have delivered crystal-clear portraits of Pluto, snapshots of distant nebulas and video of the sunrise on Mars. But this was different, because they went there. 'When astronauts are the ones seeing new things, it's all the more compelling, especially when they come home and tell us about it.'
The space race was won, but politics never sit still. 'Space was no longer the priority,' Chaikin says. A year later, 'NASA was struggling to keep its human spaceflight program alive in the face of budget cuts and political opposition.' It's easy to forget that as many or more Americans opposed government funding for trips to the moon than supported it. Even the museum admits that 'many citizens marveled at the achievement but questioned the billions of dollars it cost.'
Each time he circled the far side of the moon, he was cut off from his crewmates, from Houston, from all humankind.
Even so, the museum is less a record of the journey than a shrine to its memory. Flags are draped everywhere, and placards speak of a nation pulling together to achieve something extraordinary in a violent and unsettled age. 'We're drawn to experiences that aren't universal, that represent the farthest edge of what humans can do,' Chaikin says. 'We're compelled by 'firsts,' by extremes, by frontiers. The moon missions fit all three.'
We also remember the little things. Like the miniature harmonica and six small, silver bells that the two-man Gemini VI-A crew smuggled aboard just before Christmas 1965, which they used to play a surprise rendition of 'Jingle Bells' for their counterparts back in Houston. There's also Collins' checklist for an earlier mission on Gemini X, citing the necessity to 'prepare waste jettison bag' — another reminder that this was a human endeavor after all. And that brings me back to his watch.
At first, I was fascinated, but perplexed. Like looking at a piece of abstract art, I knew it meant something but couldn't put it into words. Then, on my way out, I saw the original model of the starship Enterprise, from 'Star Trek.' That series depicts a utopian future for humanity, beyond war and even currency. 'We've eliminated hunger, want, the need for possessions,' says Captain Jean-Luc Picard, played by Patrick Stewart, in 'Star Trek: The Next Generation.' 'We've grown out of our infancy.' In creator Gene Roddenberry's idealistic vision, humans are united in their quest for knowledge and the mysteries of the universe. In reality, the Apollo program may be the closest we've ever come to that.
The Enterprise model is a prop, like the life-sized X-wing fighter from the original 'Star Wars' trilogy that hangs from the rafters nearby. Both look cheap and uninteresting compared to the real deal, though we spend far more time as a society visiting their fictional worlds. Meanwhile, profit, rather than idealism, motivates the private companies that launch most space missions in the news today. Down the hall, the 'Futures in Space' exhibit remains under construction. But that wristwatch is real and tangible. It accompanied a man who truly went where no man had gone before.
'Not since Adam has any human known such solitude,' observed one mission control official. And out there, the watch tethered him to his home and our place in the cosmos. In outer space, where days are not days as we know them, and time itself can be warped by mass and energy, the watch kept ticking. Second by second. Collins was less philosophical about it. Reconnecting with mission control, he said, was unremarkable. He spent his time alone listening to music and looking out into the void of space. He was comfortable. The idea that he felt existential loneliness or yearning for the voice of mankind was, simply, 'baloney.' The watch doesn't disagree. Collins was a man, and nothing more, it tells me, who just happened to redefine the limits of our existence.

Mercury Retrograde Begins Soon—Here's What That Actually Means

Starting July 17, Mercury will be retrograde until August 10. During these three and a half weeks, many people expect life to go haywire—phones will break, contracts will fall through, you'll accidentally hit "Reply All" on a company-wide email. Mercury retrograde is blamed for all kinds of problems, but what is actually happening with this planet, and should you be worried? We talked to Jackie Faherty, an astrophysicist, and Susan Miller, an astrologer, to break down the science and the Faherty, PhD, senior research scientist and senior education manager at the American Museum of Natural History Susan Miller, creator of the Astrology Zone website and the apps Astrology Zone Horoscopes and Moonlight PhasesRetrograde means "backward," and during Mercury retrograde, the planet appears be moving backward in the sky. Typically, like the other planets in our solar system, Mercury moves west to east. If you were to make note of Mercury's position in the sky every evening, it would seem to be journeying a little more eastward night after night. Three or four times a year, however, it follows an east-to-west path for about three weeks, appearing to move backward. That's Mercury 14 to April 6 July 17 to August 10 November 9 to November 29All the other planets go retrograde too, though less frequently than Mercury—between once a year and once every two years. Also, the farther away a planet is from the sun, the longer the retrograde period lasts (Neptune, the most distant planet, stays retrograde for over five months). That backward movement is an optical illusion, Faherty says. "Imagine the planets are on a racetrack around the sun," she explains. "We're all moving, but we're moving at different speeds. The closer you are to the sun, the faster you go around the track." Mercury, the closest planet to the sun, moves faster than Earth. It orbits the sun in 88 days, as opposed to our 365. So about every four months, "Mercury laps us on the track, and that makes it appear to shift direction," Faherty says. "It's just a trick of perspective." Venus, the second planet from the sun, passes us every 18 months, which is when it goes retrograde (lasting about 40 days each time). As for the outer planets—Mars, Jupiter, Saturn, Uranus, and Neptune—they move more slowly than Earth does, and about once a year or (in the case of Mars) every two years, we pass one of them. That's when they appear to move backward. None of it has any deeper meaning, Fahery says. "The planets are just going around the sun, and we're looking up at the sky and seeing a visual projection of it. That's it. It's a misunderstanding to think that the location of Mercury is going to change your day." Modern-day astrologers understand that the planets aren't actually moving backward, but they still believe that the apparent motion of the planets affects us. In the world of astrology—much of which is based on Greek myth—the planets rule different areas of life. When they're retrograde, it means they're in a resting state and not in control of their domain, Miller says. As a result, those areas of life fall out of whack for humans. "We're used to getting the planets' help, but when they're retrograde, we make mistakes," she says. "Mercury is the planet of communication and travel," Miller says, explaining that anything related to these areas can get messed up during Mercury retrograde. "You shouldn't sign contracts or accept a new job or a new apartment, for example. Sometimes you have to because you can't stop your life, but keep your antenna up and ask a lot of questions." In addition to Mercury retrograde, "we feel Venus and Mars retrogrades strongly because they orbit close to Earth," Miller says. Venus rules love, beauty, and affection, according to astrology. "Don't make dramatic changes to your appearance during Venus retrograde," Miller says. Mars, which retrogrades every two years for 8 to 11 weeks, "is the energy planet. He's the gas you put in the car to make it go. When he retrogrades, everything seems to take longer and require more money." Venus next retrogrades from October 3 to November 13, 2026, and Mars retrogrades from January 10 to April 1, 2027. Miller has all the dates through 2050 on her website. There's no scientific reason to believe the planets alter the course of our lives. "Astrology does not take into account any fundamental law of physics," Faherty says, noting that astrology developed thousands of years ago, before people knew that the sun was the center of our solar system and the planets revolved around it. Mercury retrograde—or any planet appearing to move backward—would have seemed like a mysterious and even mystical phenomenon back then. "At this point, we know so much, the principle of retrograde motion is completely outdated," she adds. Also, psychologists warn about confirmation bias: the tendency to interpret information in a way that aligns with our worldview. So if you expect Mercury retrograde to affect you, you might start noticing a lot of communication- and travel-related problems over the next few weeks. But keep in mind that those are very broad categories, and issues that fall under those umbrellas are likely to occur at any time. It's just life! A 2024 Pew Research Center survey found that almost 30% of U.S. adults believe in astrology, but most of those people engage with it for fun and don't make major decisions based on it. That seems like a wise approach to Mercury retrograde—we can enjoy the myth and storytelling around it without taking it too seriously. Read the original article on Real Simple

The Dire Wolf Company's Next Target? A Giant Flightless Bird

It has taken no end of imagination for Sir Peter Jackson, the Academy Award winning—and, not incidentally, knighted—director of the Lord of the Rings and Hobbit films, to produce his entire body of cinematic work. It's a quality Jackson has had since he was a small child, when he would conjure up visions of the future. 'When I was a kid [I dreamed of] personal jet packs and flying cars and things,' Jackson said in a recent conversation with TIME. 'One of those other things I always dreamed of was to be able to bring back extinct species.' No-go on the jet packs and the flying cars. But the business of de-extinction? That's very much happening. In April, the Dallas-based biotech company Colossal Biosciences announced that it had successfully brought back the dire wolf, an animal whose howl had not been heard on Earth since the last member of the species vanished more than 10,000 years ago. Three young dire wolves currently live on a 2,000-acre preserve in an undisclosed location to protect them from the media and curiosity-seekers, and Colossal aims to produce more of the animals, with the ultimate goal of perhaps rewilding the species. Read more: The Return of the Dire Wolf The company is not stopping there. Colossal also wants to bring back the dodo, the woolly mammoth, the Tasmanian tiger—or thylacine—and more. The goal is both to increase genetic diversity and to hone genetic editing techniques to fortify existing but threatened species. Now, Colossal has announced one more species to add to its growing menagerie: the emu-like moa, a giant flightless bird that stood up to 12 ft. (3.6 m) tall, tipped the scales at more than 500 lbs (230 kg), and once ranged across New Zealand, before it was hunted to extinction by humans about 600 years ago. Like the moa, Jackson is a native New Zealander; 'I am a very proud kiwi,' he says. He is also a Colossal investor and acted as intermediary and facilitator bringing the company into partnership on the moa project with the Ngāi Tahu Research Center, a group that was founded in 2011 to foster intellectual development and conduct scientific studies for and by the Ngāi Tahu tribe of the Indigenous Māori people. 'Some of those iconic species that feature in our tribal mythology, our storytelling, are very near and dear to us,' says Ngāi Tahu archaeologist Kyle Davis, who is working on the moa de-extinction project. 'Participation in scientific research, species management, and conservation has been a large part of our activities.' 'This is completely a Māori initiative,' adds Ben Lamm, CEO and co-founder of Colossal. 'We feel like the Colossal team is an extension of the research center and the Māori.' Bringing back the moa would have implications not only for the species itself but for the environment it once inhabited and could again. The bird was what is known as a cornerstone species, one whose grazing and browsing helped prune and shape the jungle flora. Moas were also prolific dispersers of seeds from the plants they ate. The loss of the species not only eliminated that forest-restoring function, but also led to the related extinction of the Haast's eagle, which relied almost exclusively on the moa as prey. Restoring the moa would not bring the eagle back but could help at least partly restore the primal New Zealand woodlands. Bringing back the moa is of a piece with Colossal's other work, which seeks not only to restore vanished species, but to prevent related ones from slipping over the event horizon of extinction. Genetic engineering mastered in the dire wolf project, for example, is being used to edit greater diversity into the genome of the endangered red wolf. Knowledge gained in the effort to bring back the thylacine could similarly help preserve the related northern quoll. 'There are some species of birds on the South Island of New Zealand that are endangered due to the fact that they have reduced gene pools,' says Paul Scofield, senior curator of natural history at Canterbury Museum, author of 20 papers on the moa genome, and one of the scientists working on the de-extinction project. 'Some of the technology that Colossal is working with is very applicable to them.' Read more: Scientists Have Bred Woolly Mice on Their Journey to Bring Back the Mammoth That technology is decidedly challenging. De-extincting the dire wolf involved sequencing ancient DNA collected from fossil specimens and then rewriting the genome of cells from a gray wolf to resemble the extinct species with the lost ancient genes. The edited nucleus was then inserted into a domestic dog ovum whose own nucleus had been removed. That ovum was allowed to develop into an embryo in the lab and then implanted into the womb of a surrogate domestic dog, which carried the dire wolf pup to term.' Bringing back the extinct moa is harder since the incubating will be done outside the body, inside an egg. The first step in this work once again calls for sequencing the genome of the extinct target species and once again turning to a closely related living species—either the tinamou or the emu—for help. Colossal scientists will extract primordial germ cells—or cells that develop into egg and sperm—from a tinamou or emu embryo and rewrite their genome to match key features of the moa. Those edited cells will then be introduced into another embryonic tinamou or emu inside an egg. If all goes to plan, the cells will travel to the embryo's gonads, transforming them so that the females produce eggs and the males produce sperm not of the host species but of the moa. The result will be an emu or tinamou that hatches, grows up, mates, and produces eggs containing moa chicks. 'We've had some pretty big successes so far,' says Lamm. 'We have a breeding colony of tinamous but not emus, but have access to emu eggs through the many breeders out there." None of this means that the work is remotely done. Lamm concedes it could be up to ten years before a moa once again walks New Zealand—though it could come sooner. 'I'd rather underpromise and overdeliver,' he says. For now, Colossal and the Ngāi Tahu Research Center are still working to sequence the moa genome, and to do that they have to get their hands on more DNA samples. Museum specimens of moa remains satisfy some of that demand, but DNA degrades significantly over the centuries and what can't be harvested from private collections has to be dug up in field excavations—with a special eye to long, DNA-rich moa bones like the femur and tibia. 'There are a couple of really significant fossil sites, particularly one in North Canterbury, about an hour north of Christchurch,' says Scofield. 'So far we've sampled more than 60 individuals.' If those don't prove sufficient, he adds, 'we will have to go out and dig some more holes.' None of this comes cheap, and while Lamm does not disclose the exact funding for the moa de-extinction project, he does say it is an eight-figure sum. 'I saw the new Jurassic World movie and someone in it says it costs $72 million to bring back one animal,' he says. 'I was like, 'That's probably accurate.'' That up-front expenditure could pay off handsomely down the line, boosting ecotourism to New Zealand and benefiting Colossal's basic research, which is already showing for-profit potential. So far, Colossal has spun off two new companies: One, called Breaking, uses engineered microbes and enzymes to break down plastic waste. The other, Form Bio, provides AI and computational biology platforms for drug development. But it's the intangibles—the wonder of midwifing a long-extinct species back to the global family of extant ones—that is Colossal's and the Māori's most transcendent work. 'This has an excitement value to it that movies don't have,' says Jackson. 'When I see a living moa for the first time I'm going to be absolutely amazed beyond anything I've ever felt.'

What is VO2 max? The metric that could give you better workouts

On TikTok, VO2 max is going viral as the key to improving your endurance during a workout, but what exactly does it measure? In short, you can think of this metric as the maximum amount of oxygen your body uses during exercise – V stands for volume, and O2 stands for oxygen, per Harvard Health. But what do you gain from trying to increase it? For some people, improving VO2 max could help you attain longer, sustained workouts, and offer potential cardiovascular benefits, experts say. So, whether you're an athlete, or simply trying to improve your performance during exercise, here's why it might be worth taking a closer look at your VO2 max. As the heart pumps oxygen-rich blood throughout the body, it delivers oxygen to your muscles. Our muscles then utilize oxygen to produce adenosine triphosphate (ATP), which provides energy, says Heather Milton, a board-certified clinical exercise physiologist, and certified strength and conditioning specialist with NYU Langone. '(VO2 max is) a function of your cardiorespiratory system to (be) able to transmit oxygen from the air around you into your lungs and into your circulatory system,' says Dr. Christopher Tanayan, a sports cardiologist and Director of Sports Cardiology at Lenox Hill Hospital at Northwell Health. The most accurate way to calculate your VO2 max is in a clinical setting, says Tanayan. 'A CPET (cardiopulmonary exercise test) is the gold standard of estimating someone's VO2 max,' he says. In the setting of a performance center, this test might also be referred to as an aerobic capacity test, or a VO2 max test, says Milton. During a CPET, you'll wear a mask that records the amount of oxygen you inhale, the amount of carbon dioxide you exhale and your number of respirations per minute. 'Essentially, the mask is measuring the volume of air that we're taking in,' says Milton. You'll complete a series of exercises (typically using treadmills or bikes) that become increasingly strenuous over time. The test continues until you reach a point where you're no longer able to consume and deliver oxygen to your muscles – that number is your VO2 max, Tanayan says. Your VO2 max is measured in mL/kg/min (milliliters of oxygen consumed per kilogram of body weight per minute of exercise), according to Harvard Health. Another way to find your VO2 max is using a wearable (such as a Fitbit, Garmin or Apple Watch) to track your performance during exercise. With a bit of math and extrapolation, wearables can approximate the amount of energy you're using during your workout by measuring your heart rate response to submaximal efforts, ideally taking into account your age, weight and sex, says Milton. Are you exercising 'in the zone'? All about Zone 2 cardio. Ultimately, 'there is no perfect VO2 max score – it varies from individual to individual,' says Tanayan. There are lots of variables that go into calculating your VO2 max, including your genetics, age, sex, fitness level and altitude that you're exercising at, says Dr. Amadeus Mason, an assistant professor in the othopaedics and family medicine department at Emory University School of Medicine, and the chief medical officer for Atlanta United FC and medical director for Team USA Track & Field. A higher VO2 max could indicate better cardiovascular fitness and endurance – this means you'll be able to move and sustain more activity for longer periods of time, says Mason. Research shows there may be a potential correlation between having a higher VO2 max, and decreased risk for cardiovascular diseases, per Harvard Health. However, the metric alone should not be interpreted as an indicator of overall health, Mason underscores. In case you missed: Any physical activity burns calories, but these exercises burn the most From a training standpoint, once you know your VO2 max, there are steps you can take to improve this number, which could increase your endurance during a workout. Still, not everyone needs to train to improve their VO2 max; it really depends on your exercise goals. For example, if you're an anaerobic athlete (i.e. a weightlifter or sprinter) who needs short bursts of power to get through a workout, training to increase your VO2 max might not be necessary, says Milton. On the other hand, if you perform a mix of aerobic (a.k.a. cardio) and anaerobic exercise, there are benefits to improving your VO2 max. Having a solid aerobic base promotes 'fast recovery in between bouts of high intensity (or anaerobic) exercise,' Milton says. For the general population, improving your VO2 max could also help with enhanced longevity and potential cardiovascular benefits, she says. To increase your VO2 max, try out these types of exercise, experts say: HIIT. Incorporate high intensity interval training (HIIT) into your workout routine, recommends Mason. There's a misconception that HIIT only consists of high impact exercises like jumping jacks, burpees and squat jumps, says Milton. However, because the ultimate goal of HIIT is to elicit a heart rate response, low-impact HIIT exercises could include incline treadmill walking, using an elliptical or working out with a stationary bike, she says. Cardio. For the non-professional athlete, one of the best ways to improve your VO2 max is by performing consistent aerobic exercise, says Mason. To get your heart rate and oxygen intake up, try steady-state cardio exercises like running, jogging, cycling or swimming. Resistance training. It's easy to slip into a pattern of only doing cardio as your sole mode of exercise, but resistance training is equally important, says Milton. Resistance training helps maintain muscle mass, and enhances the quality of the muscle you already have. It also lends itself to a few other benefits, including enhanced longevity, balance and agility and fall prevention, she says. This article originally appeared on USA TODAY: What is VO2 max?
