What is *Exercised* by Daniel E. Lieberman about?

*Exercised* explores why humans evolved to avoid unnecessary physical activity and how modern lifestyles clash with our biology. Combining evolutionary anthropology and cutting-edge research, Lieberman debunks myths about exercise (e.g., sitting isn’t inherently harmful) and offers science-backed strategies to stay active sustainably. The book reframes exercise as a voluntary, health-promoting behavior rather than an innate instinct.

Who should read *Exercised*?

Fitness enthusiasts, evolutionary biology buffs, and anyone struggling to maintain consistent exercise habits will benefit. Lieberman’s insights are particularly valuable for those seeking evidence-based approaches to combat sedentary lifestyles or overwhelmed by conflicting fitness advice. Health professionals and educators will also appreciate its interdisciplinary perspective on human movement.

Is *Exercised* worth reading?

Yes. Lieberman’s myth-busting approach (e.g., challenging the “10,000 steps” rule) and engaging storytelling make complex science accessible. The book’s practical advice—like prioritizing enjoyable activities over grueling workouts—helps readers build sustainable habits. Its evolutionary lens offers a fresh take on modern health crises, distinguishing it from conventional fitness guides.

How does evolutionary biology explain human exercise habits?

Our ancestors stayed active through survival tasks (hunting, gathering) rather than deliberate exercise. Lieberman argues that conserving energy was evolutionarily advantageous, which explains why modern humans instinctively avoid unnecessary exertion. Industrialization reduced daily movement, making voluntary exercise essential for health.

What exercise myths does *Exercised* debunk?

- **Myth 1:** Sitting is “the new smoking.” Lieberman shows sedentary behavior isn’t harmful if balanced with regular activity. - **Myth 2:** High-intensity workouts are superior. Moderate, consistent movement (e.g., walking) better aligns with our evolutionary needs. - **Myth 3:** Exercise alone guarantees weight loss. Diet and non-exercise activity play larger roles.

What practical tips does *Exercised* offer for staying active?

- Choose enjoyable activities (dancing, hiking) over dreaded gym sessions. - Integrate movement into daily routines (walking meetings, household chores). - Focus on consistency, not intensity: 150 minutes/week of moderate exercise suffices.

How does inactivity contribute to chronic diseases?

Hunter-gatherers remain active into old age, avoiding conditions like diabetes and heart disease common in sedentary societies. Lieberman links modern inactivity to weakened muscles, poor circulation, and metabolic dysregulation, emphasizing that regular movement is preventive medicine.

Does *Exercised* recommend specific workout routines?

No. Lieberman advises against one-size-fits-all regimens. Instead, he advocates for diverse, moderate activities (e.g., brisk walking, gardening) that align with individual lifestyles. The goal is to make movement rewarding, not punitive.

The Evolution of Exercise: Why Something We Never Evolved to Do is Vital for Our Health

When was the last time you felt guilty for not exercising? Perhaps you've joined the 67 million Americans with gym memberships, or maybe you're among the 80% who rarely use them. Daniel Lieberman's groundbreaking book "Exercised" tackles a fundamental paradox: if exercise is so good for us, why do most people avoid it? As Harvard's Edwin M. Lerner II Professor of Biological Sciences and a renowned researcher in human evolution, Lieberman brings unique authority to this question. The book has resonated with everyone from elite athletes to chronic exercise-avoiders, landing on Barack Obama's 2021 summer reading list and influencing fitness programs worldwide. Lieberman, sometimes called "the Barefoot Professor" for his research on running evolution, takes us on a journey that fundamentally challenges how we think about physical activity, offering a perspective that's both scientifically rigorous and surprisingly liberating.

The Paradox: Born to Move, Programmed to Rest

Imagine meeting Ernesto, an elderly Tarahumara man from Mexico's Sierra mountains. Despite being in his seventies, he remains remarkably fit-yet he never "exercises." When asked about training for running competitions, Ernesto was incredulous at the concept of "needless running," asking why anyone would run when they didn't have to. As a subsistence farmer who grows all his food without machines, Ernesto's perspective challenges our assumptions about exercise and highlights how bizarre Western exercise habits might appear to those living traditional lifestyles. This reveals the central paradox Lieberman explores: humans evolved to be physically active but also to avoid unnecessary exertion. Our ancestors walked miles daily, carried heavy loads, and occasionally sprinted from predators-not because they wanted to stay fit, but because their survival depended on it. Meanwhile, they rested whenever possible to conserve precious calories. This evolutionary legacy explains why exercise feels like a chore for many people. We're fighting against deep-seated instincts that evolved over millions of years. When you take the escalator instead of the stairs or circle a parking lot looking for a closer spot, you're not being lazy-you're following ancient programming to conserve energy. In environments where food was often scarce, individuals who needlessly burned calories had lower chances of survival and reproduction than those who conserved energy when possible. The problem isn't our natural inclination to rest-it's that modern environments have made physical activity optional while making calorie-dense food abundant. This "mismatch" between our evolved tendencies and current environment explains why half of American adults and three-quarters of teenagers fail to meet basic activity guidelines, contributing to epidemic levels of chronic disease.

The Myth of the Athletic Savage

Popular culture often romanticizes indigenous peoples like the Tarahumara as natural superathletes untainted by civilization. Lieberman challenges this "athletic savage" myth through his fieldwork with groups like the Hadza hunter-gatherers of Tanzania. What surprised him most upon first visiting a Hadza camp was finding everyone sitting and apparently doing nothing-contrary to expectations of constantly active hunter-gatherers. While Hadza do leave camp daily to hunt and gather, with women walking miles to dig for tubers and men tracking animals for 7-10 miles, much of their time in camp is spent resting, socializing, and performing light tasks while seated. Their hunting pace varies but remains manageable, with frequent stops to rest or collect food like honey. Measurements of hunter-gatherers like the Hadza reveal they are lean and modestly strong but not muscular. The average Hadza man is 5'4" and 117 pounds, with grip strength within Western norms. Unlike modern gym-goers, hunter-gatherers lack the means to bulk up systematically, and excessive muscle mass would require substantial additional calories-up to 300 daily-that would be challenging to obtain in the wild. Using the Physical Activity Level (PAL) metric, hunter-gatherers average PALs of 1.9 for men and 1.8 for women-slightly below subsistence farmers (2.1/1.9) but above sedentary office workers (1.6). Strikingly, hunter-gatherers are substantially less active than wild mammals (PAL 3.3+) and roughly equivalent to modern people who exercise about an hour daily. This evidence contradicts the notion that our ancestors were constantly active superathletes. Rather, they were physically active enough to survive but also conserved energy when possible-a balanced approach that modern exercise programs might do well to emulate.

How Exercise Became Weird

Exercise-planned physical activity for self-improvement-is uniquely human and historically recent. While play is universal among young mammals and sports have always existed in human cultures, deliberate exercise outside of sports emerged only recently. Our ancestors moved constantly as part of daily survival, from hunting and gathering to farming and crafting, never needing to consciously "exercise." Ancient societies primarily exercised for combat preparation, with military training being the first formalized exercise systems. The Greeks developed the gymnasium culture, where physical training merged with intellectual pursuit. Philosophers like Plato advocated for exercise as essential to developing both body and mind, while Hippocrates prescribed specific exercises for health. In China, Confucius promoted physical activity for moral development, and traditions like Qigong combined movement with spiritual practice. Exercise gained popularity during the Renaissance as humanist thinking emphasized the complete development of the individual. However, structured exercise remained largely confined to aristocrats and military academies. The Industrial Revolution marked a crucial turning point - as machines replaced physical labor, the newly expanded middle class began seeking ways to stay active. This period saw the birth of modern gymnastics, calisthenics, and organized sports. For centuries, experts have worried about insufficient exercise, driven by nationalism and health concerns. Friedrich Jahn's Turner movement in 19th century Germany promoted gymnastics as a way to build national strength after Napoleon's victories. Similar movements emerged across Europe and America, with schools introducing physical education programs. The early 20th century saw the rise of fitness entrepreneurs like Bernarr Macfadden and Charles Atlas, who marketed exercise systems to the masses. Today, exercise has become thoroughly commodified, commercialized, and medicalized. Government agencies issue detailed physical activity guidelines. The fitness industry offers endless specialized equipment, from treadmills to smart watches. Gym memberships have become status symbols, while "athleisure" fashion has turned workout wear into everyday clothing. This represents a trillion-dollar global industry built on our disconnect from natural movement. This transformation has made physical activity seem unnatural and burdensome. Rather than integrating movement into daily life as our ancestors did, we've compartmentalized it into dedicated "workout" sessions that many people dread. We drive to gyms to walk on treadmills, lift weights to compensate for sedentary jobs, and track every step with digital devices. Understanding this historical shift helps explain our complicated relationship with exercise and points toward more sustainable approaches that reintegrate movement into daily life, from active transportation to movement-friendly workspaces.

The Truth About Sitting and Sleeping

Despite headlines claiming "sitting is the new smoking," Lieberman presents evidence that sitting itself isn't inherently harmful-it's natural and ancient. What's problematic is hours of inactive sitting combined with little exercise. Humans sit to conserve energy-sitting uses 8-10% fewer calories than standing, amounting to about eight calories per hour for a 175-pound adult. Anthropologists have documented over a hundred chairless sitting postures across 480 cultures, with squatting being particularly common throughout human evolutionary history. The real issue is that modern lifestyles often involve prolonged, uninterrupted sitting. Studies show that even fit individuals who sit extensively face higher risks of inflammatory diseases. People who take frequent short breaks from sitting show up to 25% less inflammation despite sitting the same total hours. These brief activity breaks activate muscles to consume blood sugar and fat, reducing inflammation. Similarly, sleep myths abound. Despite the common prescription of eight hours of sleep per night, this guideline lacks solid scientific foundation. Studies of non-industrial populations like Hadza hunter-gatherers, San forager-farmers, and Amazonian hunter-farmers reveal they typically sleep only 5.7-7.1 hours nightly, with longer sleep in colder months. Contrary to popular belief, modern industrial populations don't sleep less than non-industrial ones, and sleep duration hasn't decreased significantly in the last fifty years. More surprisingly, health data from over one million Americans showed that those sleeping 6.5-7.5 hours had 12% lower mortality rates than eight-hour sleepers. These findings suggest that many modern anxieties about sitting and sleeping are misplaced. Rather than obsessing over perfect posture or precise sleep hours, we should focus on incorporating regular movement throughout the day and developing sustainable sleep patterns that work for our individual needs.

Speed, Strength, and Power Through an Evolutionary Lens

Despite Usain Bolt's incredible speed, he's actually quite slow compared to most quadrupedal mammals. While he can outrun skunks, rhinos, hippos and squirrels, he would stand no chance against most mammals like zebras, giraffes, wildebeests, deer, or predators like grizzly bears and hyenas. Our bipedal evolution doomed humans to relative slowness. While four-legged animals have multiple limbs generating force against the ground simultaneously, humans run with only one leg pushing at a time, producing less power and speed. Unlike specialized bipedal runners like ostriches, humans inherited cumbersome primate legs and feet that limit our speed. However, humans evolved exceptional endurance running abilities primarily to acquire meat through two strategies: power scavenging and persistence hunting. Power scavenging involved running to carcasses spotted from vultures circling overhead, often during hot midday when humans could outrun hyenas due to superior heat tolerance. Persistence hunting exploited humans' unique ability to run without overheating. Hunters would chase prey during the hottest part of day, allowing animals to sprint away but then tracking and pursuing them repeatedly before they could fully cool down. This evolutionary history explains why humans can outrun horses in endurance contexts. While horses can gallop faster than humans can sprint, they cannot maintain galloping speeds for long distances, especially in heat. Most quadrupeds must slow to a trot for endurance, and humans can run marathons at speeds exceeding the trotting speeds of greyhounds, ponies, and sometimes even horses. Our strength evolved differently as well. Unlike chimpanzees whose daily lives involve frequent violent confrontations, humans fight far less often-250 to 600 times less frequently than chimps. We've traded some brawn for brains, developing the ability to cooperate and use weapons, which reduced the advantage of large body size in combat. This explains why human sexual dimorphism (size difference between males and females) has decreased over evolutionary time.

Endurance: The Human Superpower

While we may not be the fastest or strongest species, humans possess remarkable endurance capabilities. The author demonstrated this by competing in the "Man Against Horse" race in Arizona, where he successfully beat 40 of 53 horses over a 25-mile mountain course. This experience connects to research showing that by two million years ago, Homo erectus had evolved the necessary anatomy to run long distances in heat for hunting and scavenging. Human endurance running ability stems from our long, springy legs with elastic tendons like the Achilles, which store and return energy during running. These adaptations evolved independently in humans, as our ape relatives lack these springy tendons. For endurance speeds, good human runners have lower stride rates and similar stride lengths to horses, though horses can easily outpace humans when sprinting. Walking represents another endurance superpower. While walking appears effortless, it involves dozens of muscles working in complex patterns to both move efficiently and prevent falling. The mechanics of walking operate on pendulum principles, allowing humans to walk far more efficiently than our knuckle-walking ape relatives. Our bipedal evolution saves tremendous energy: walking upright saves approximately 2,400 calories weekly compared to knuckle-walking, enough energy annually to run 45 marathons. This efficiency allowed our ancestors to travel longer distances in search of food and resources, a crucial adaptation as climate change fragmented African rainforests 7-9 million years ago. Dancing emerges as another vital endurance activity in human evolution. In nonindustrial societies like the San, dancing serves multiple purposes beyond enjoyment-healing the sick, warding off evil, and building community bonds. These dances require phenomenal endurance, often lasting through the night. Dancing parallels running physiologically-both involve jumping from one leg to the other, build endurance, and can induce altered states through brain chemicals like endocannabinoids.

The Active Grandparent Hypothesis

How does endurance activity affect aging? Lieberman explores this through what he calls the "Active Grandparent Hypothesis." Unlike chimpanzees who rarely live past fifty, humans typically survive decades beyond reproductive age. This evolutionary puzzle is explained through the "grandmother hypothesis": elderly humans contribute to their genetic success by provisioning and caring for younger generations, creating a unique evolutionary advantage that separates humans from other primates. Hunter-gatherer grandparents remain remarkably physically active well into their later years. Hadza grandmothers, for instance, forage 5-6 hours daily-longer than mothers of young children. They collect tubers, berries, and other plant foods, often walking 3-4 miles per day across challenging terrain. While Americans typically reduce their walking by 50% in their seventies compared to their forties, elderly Hadza maintain brisk walking speeds averaging 2.5-3 mph and demonstrate higher fitness levels into old age. This stark contrast highlights how modern sedentary lifestyles deviate from our evolutionary heritage. Lieberman explains how exercise combats aging through the "costly repair hypothesis." Exercise initially stresses the body, causing microscopic damage to muscles, bones, and other tissues, but this triggers powerful repair mechanisms that fix not just exercise-induced damage but pre-existing damage throughout the body. These repair mechanisms can even overcompensate, making tissues stronger than before - a process called supercompensation. For example, bone density increases in response to impact exercise, and muscle fibers become more resistant to damage after repeated use. Our bodies evolved sophisticated systems to match repair capacity to physical demand, activating maintenance mechanisms in response to activity levels. These include increased production of antioxidants, enhanced DNA repair, improved insulin sensitivity, and better mitochondrial function. Without regular exercise, these mechanisms aren't activated effectively, causing faster aging. The author argues that humans never evolved to counter aging processes without physical activity, making sedentary living a "mismatch condition" that accelerates senescence. This explains why conditions like osteoporosis, sarcopenia, and cardiovascular disease are more prevalent in inactive populations. The evidence shows it's never too late to benefit from exercise-even people who become physically active after age sixty can reduce their mortality rates by 30-40% compared to those who remain sedentary. Studies of masters athletes in their 70s and 80s demonstrate that they maintain muscle mass, bone density, and cardiovascular function at levels more typical of people decades younger. This evolutionary perspective helps explain why exercise becomes increasingly important as we age, not less, and suggests that regular physical activity is fundamental to healthy aging rather than optional. The Active Grandparent Hypothesis ultimately reveals that human longevity evolved hand-in-hand with physical activity, making exercise not just beneficial but essential for maintaining health throughout our extended lifespans. This understanding challenges modern notions of retirement as a time of reduced activity and suggests instead that continued physical engagement is key to fulfilling our evolutionary potential for healthy aging.

How to Make Exercise Happen

If we're naturally inclined to avoid unnecessary exertion, how can we establish sustainable exercise habits? Lieberman describes his illuminating experience at Bjorn Borg sportswear company in Stockholm, where CEO Henrik Bunge implemented mandatory weekly exercise for all employees. Every Friday at 11:00 a.m., the entire company-from executives to mail room staff-heads to a nearby gym for "Sports Hour." The program includes various activities from traditional workouts to team sports, ensuring options for different fitness levels and preferences. While initially skeptical about this coercive approach, Lieberman interviewed numerous employees about their experiences. He learned that when Henrik implemented the program in 2014, about 20% of staff quit, but remaining employees now largely appreciate the benefits. Many admitted Sports Hour was their only weekly exercise, and all noted it fostered community and camaraderie across management levels. The program has led to measurable improvements in productivity, reduced sick days, and increased job satisfaction. Even those who initially resisted now report looking forward to these sessions. This highlights a key insight: social commitment powerfully motivates physical activity. Rather than relying solely on willpower, we can leverage social connections to make exercise more sustainable. Exercise with friends, join group classes, sign commitment contracts with financial penalties, or register for events that require training. Research shows that people who exercise with partners are 95% more likely to maintain their routines compared to solo exercisers. Successful strategies include joining running clubs, participating in team sports, or simply having a regular walking partner. Lieberman delves deep into the neurochemistry of exercise motivation. He explains how exercise produces mood-enhancing neurochemicals that create positive feedback loops for regular exercisers but can work against non-exercisers. Serotonin helps us feel pleasure and control impulses, endorphins help tolerate discomfort during exertion, and endocannabinoids (not endorphins) are primarily responsible for the runner's high. These chemical responses become stronger and more rewarding with consistent exercise, typically after 6-8 weeks of regular activity. These reward systems create a mismatch problem: they work well for active people but poorly for sedentary individuals. The author recommends making exercise more enjoyable through social activity, entertainment (music, podcasts), exercising outdoors, dancing, sports, setting realistic goals, and rewarding yourself. He suggests starting with just 10-15 minutes of daily activity and gradually increasing duration and intensity. Most importantly, understanding that it takes months of consistent effort before exercise becomes rewarding. Success stories often involve people who stuck with moderate activity for at least three months before experiencing significant psychological benefits. To overcome initial resistance, Lieberman recommends "habit stacking" - attaching exercise to existing daily routines, like morning coffee or commuting. He also emphasizes the importance of removing barriers by preparing workout clothes the night before, keeping equipment easily accessible, and scheduling exercise at consistent times. The key is making physical activity a non-negotiable part of daily life, just like brushing teeth or showing up for work.

Exercise as Medicine: Preventing and Treating Disease

Physical activity helps prevent cardiovascular disease by addressing the three primary causes: high cholesterol, high blood pressure, and inflammation. Exercise improves cholesterol profiles by lowering triglycerides, raising beneficial HDL levels, and somewhat reducing harmful LDL. It combats high blood pressure by stimulating the growth of new blood vessels and keeping existing arteries supple and elastic. The heart adapts to regular exercise by becoming stronger and more efficient, pumping more blood with each stroke. For metabolic health, exercise can dramatically reverse type 2 diabetes, as demonstrated when ten overweight Australian aborigines with the disease returned to hunting and gathering for just seven weeks. Physical activity ameliorates every aspect of metabolic syndrome: it reduces organ fat, lowers blood pressure, improves blood sugar and cholesterol levels, reduces inflammation, and counteracts stress effects. Most remarkably, exercise reverses insulin resistance by restoring blocked insulin receptors and increasing glucose transporters in muscle cells-effectively unclogging the metabolic drain. Exercise is the most effective known prevention and treatment for Alzheimer's, with studies showing moderate physical activity lowers risk by 45%. Physical activity stimulates production of BDNF (brain-derived neurotrophic factor), a growth tonic that nourishes brain cells and induces new ones, especially in memory regions. One study found women with highest BDNF levels have half the risk of developing Alzheimer's compared to those with lowest levels. The connection between physical and mental health is substantial-regular exercisers report 12-23% lower levels of mental health problems than sedentary people. Numerous high-quality studies confirm exercise helps prevent and treat depression and anxiety disorders, with effectiveness equal to or greater than drugs and psychotherapy.

A Philosophy for Using Your Body

Lieberman concludes with a powerful insight: developing a philosophy for using one's body is just as crucial as cultivating a philosophy for living. Our ancient instincts, which evolved to conserve energy by avoiding unnecessary physical exertion, now work against us in the modern world. Following these instincts increases our chances of faster aging, earlier death, and vulnerability to chronic diseases, while simultaneously depriving us of physical and mental vigor that regular activity provides. Though exercise guarantees nothing, our evolutionary history demonstrates that lifelong physical activity dramatically increases our chances of dying healthy after seven or more decades. The scientific evidence is clear: populations that maintain regular physical activity throughout life show significantly lower rates of cardiovascular disease, diabetes, and cognitive decline. The advice, while straightforward, is backed by millions of years of human evolution: Make exercise necessary and enjoyable. Focus primarily on cardiovascular activities like walking, running, or swimming, but include strength training to maintain muscle mass and bone density. Even modest amounts of activity provide benefits - some movement is invariably better than none. Crucially, maintaining activity levels becomes even more important as we age, when natural tendencies toward sedentary behavior increase. Rather than shaming or stigmatizing those who avoid exertion, society should focus on creating supportive environments that make physical activity accessible, enjoyable, and socially rewarding. This means designing walkable cities, creating safe spaces for recreation, and fostering community activities that naturally incorporate movement. We should treat exercise like education - as an essential component of human development and wellbeing - rather than as medicine to be reluctantly consumed. Understanding our evolutionary heritage explains not only why exercise feels challenging (it was meant to be reserved for necessary activities), but also liberates us from guilt and provides practical strategies for incorporating sustainable physical activity into our modern lives. By viewing exercise through an evolutionary lens, we can develop a healthier and more sustainable relationship with physical activity. This perspective helps us acknowledge our natural tendencies to conserve energy while creating environments and habits that help us thrive in the modern world. It suggests focusing on activities that mirror our ancestral movements - walking, carrying, climbing, and playing - while building social connections and finding genuine enjoyment in movement. This approach makes physical activity a natural, integrated part of daily life rather than a burdensome obligation to be endured.

저는 24년째 PhotoReading 속진 학습 강사로 일하고 있어요… 책과 독서, 배움이 제 전문인데, BeFreed는 정보를 소화하기 쉽게 전달하는 혁신적인 방식을 정말 잘 구현했어요.

@BeFreed user

단순한 책 요약 앱이 아니에요. '재미' 스타일을 써 봤는데, 전통적인 방식보다 훨씬 나은 요약이고 아이디어를 이해하기도 쉬워요. 이것만으로도 값어치를 해요.

@austinakon

이 앱이 정말 좋아요. 며칠 써 봤는데 듣는 걸 멈출 수가 없어요. 시작하기에 이보다 좋을 수 없어요.

@jcrules328

정말 마음에 들어요. 한 달 정도 써 봤는데 숨은 보석을 찾은 기분이에요. BeFreed로 제가 원하는 주제를 직접 만들 수 있어서 좋고, 목소리도 훌륭한 데다 내레이션 선택지가 무궁무진해요.

@DanielCZ

정말이지 아직 앱을 다 써 보지도 않았는데, 며칠 써 본 것만으로도 깊은 인상을 받았어요… BeFreed는 제가 써 본 어떤 학습 앱과도 차원이 달라요. 몰입감이 엄청나고 집중력도 실제로 좋아져서, 스마트폰을 하염없이 스크롤하는 분들께 딱이에요!

@ladyInfinity

정확히 23일 전에 BeFreed를 구입했는데, 그날부터 하루도 빠짐없이 쓰고 있어요. 제 일상 업무 흐름과 학습 습관에 완전히 자리 잡았어요.

@jayallen

솔직히 이 앱은 제 기대를 전부 뛰어넘었어요. 어떤 주제든 오디오로 만들어 달라고 할 수 있고, 결과물이 놀라워요. 제 전문 분야는 심리치료 쪽이고 여러 학문이 얽혀 있는데도 답변이 아주 정확해요.

@DanielCZ

유용한 정보와 아이디어를 8~15분짜리 팟캐스트 스타일 오디오로 압축해서 들을 수 있다는 게 정말 좋아요. 원래 팟캐스트는 군더더기가 많아서 안 좋아했는데, 여기는 그걸 싹 걷어냈어요.

@BeFreed user

박사 과정을 마무리하는 중이라 낯선 자료를 많이 읽어야 해요… BeFreed에서는 프롬프트만 입력하면 앱이 자료를 찾아서 오디오 팟캐스트로 만들어 줘요. BeFreed의 과정이 NotebookLM보다 더 매끄럽게 느껴져요.

@Brad

아침을 준비하거나 산책하거나 출퇴근할 때 들을 것을 YouTube에서 자주 찾곤 했는데, BeFreed는 광고도 군더더기도 없이 훨씬 더 딱 맞는 걸 들려줘요!

@BeFreed user

이 플랫폼의 가장 큰 장점은 활용도예요. 다루지 못하는 주제가 말 그대로 하나도 없어요. 무엇을 던져도 다 소화해요… 제한이 전혀 없으면서 약속을 실제로 지키는 학습 도구는 정말 드물어요.

@jayallen

BeFreed는 환상적이에요. 디자인이 편해서 헤매는 시간은 줄고 배우는 시간은 늘었어요. 오디오북, 팟캐스트, 학습 플랜의 조합은 천재적이에요. 제 하루가 완전히 달라졌어요.

@BeFreed user

처음엔 이탈리아어로 팟캐스트를 만드는 방법을 이해하는 데 시간이 좀 걸렸는데, 알고 나니까 — 와! 정말 대단해요! 어떤 주제든 설명해 달라고 하면 정말 똑똑하게 잘 설명해 줘요!

@matteo77

BeFreed는 제가 매일 쓰는 오디오북 앱이 됐어요… 제일 마음에 드는 건 텍스트를 넣으면 이동 중에도 들을 수 있는 오디오로 만들어 준다는 점이에요.
