In a nutshell

  • Physical appearance is the top motivator for exercise (24%), outranking physical health (19%) and mental health (17%), according to analysis of Reddit discussions.
  • Building consistent habits is the most effective strategy for maintaining exercise routines, with 30% of users emphasizing routine over motivation.
  • During the COVID-19 pandemic, motivations shifted significantly – physical appearance became less important while health benefits gained greater prominence.

TEL AVIV — Vanity trumps health when it comes to why people start exercising. This surprising finding emerged when Tel Aviv University researchers took an unconventional approach to studying fitness motivation: they analyzed unfiltered Reddit conversations instead of using traditional surveys. Their data revealed physical appearance was the top motivation (24% of comments), with physical health (19%) and mental health (17%) trailing behind.

When it comes to sticking with exercise, building consistent habits proved most crucial, with Redditors emphasizing that discipline matters far more than fleeting motivation.

‘In reality, they want six-pack abs’

The study, published in the Journal of Medical Internet Research, offers a rare glimpse into what people say about exercise when they’re speaking freely, not responding to researcher-designed questions. Researchers Michal Shmueli-Scheuer, Yedidya Silverman, Israel Halperin, and Yftach Gepner analyzed 1,577 unique comments from fitness-focused and general advice Reddit communities to uncover these patterns.

Despite mountains of evidence supporting the benefits of exercise, more than 80% of adolescents and 27% of adults worldwide fail to meet the World Health Organization’s minimum activity guidelines. This persistent gap between knowing exercise is good and actually doing it drives researchers to better understand what truly gets people moving.

Traditional research on exercise motivation typically relies on questionnaires and structured interviews. While these approaches yield valuable data, they come with blind spots. Study participants represent a self-selected group — people already interested enough in exercise to volunteer for research. Scientists call this “volunteer bias,” meaning participants often differ from the general population in key ways.

Questionnaires can also subtly influence responses. The phrasing might confuse participants or nudge them toward certain answers. People may give what they think are socially acceptable answers or try to guess what researchers want to hear, a phenomenon known as “demand characteristics.”

“Our findings are not based on self-reporting, a representative sample, a questionnaire, or a survey. This is, in plain terms, the real reason why people exercise. And the answer is that people mainly exercise to look good,” explains Prof. Gepner in a statement. “In questionnaires, people claim they want to be healthy, but in reality, they want six-pack abs. These findings are important because they teach us how to address the public, how to persuade people to get off the couch, promote health, and prevent disease.”

When it comes to exercise, some need than motivation

By turning to Reddit, the Tel Aviv team gained access to conversations happening naturally, without research prompts. Reddit’s anonymity likely encourages more candid sharing, as users don’t worry about judgment from people who know them personally.

They analyzed comments from six different subreddits: r/bodyweightfitness, r/crossfit, r/Fitness, r/askMen, r/askWomen, and r/askReddit. Using natural language processing, they categorized discussions into two main themes: reasons for starting exercise and tactics for maintaining exercise routines.

Beyond the top three motivational factors (appearance, physical health, and mental health), the analysis revealed seven key strategies people use to stick with exercise. Habit formation dominated at 30%, followed by goal setting (14%), choosing enjoyable activities (12%), socializing (10%), using media like music or videos (9%), tracking with apps (2.8%), and financial commitment (2.5%).

Many Reddit users emphasized that motivation alone isn’t enough. As one commenter bluntly put it: “Motivation depends on emotions which are unstable. Discipline is the ability to maintain a habit even when the motivation isn’t there.”

For goal setting, commenters stressed concrete targets: “You really have to want it. If you don’t care to change or don’t have any numerical goals, you won’t last. Set some goals and really strive to meet them.”

Finding activities you genuinely enjoy was another major theme. “I hate going on runs or going to lift weights at the gym. I can’t get motivated to do that,” wrote one user. “But if I take a spin class or kickboxing or muscle endurance class I love it. It’s all about finding something you like.”

The COVID-19 pandemic shifted these priorities notably. Comparing pre-pandemic and pandemic-era comments showed physical appearance became less important (dropping from 26% to 19%), while physical and mental health grew more significant (rising from 17% to 25% and 15% to 24%, respectively). This reflects how the global health crisis reshaped priorities.

Wise redditor advice: ‘Do something fun for exercise’

The researchers also tracked which topics appeared together most frequently. Physical and mental health often showed up in the same comments, as did app monitoring and goal setting. This suggests people typically have multiple reasons for exercising and use several strategies simultaneously to stay consistent.

The team went beyond counting mentions by analyzing which topics received the most positive reception through Reddit’s upvoting system. Habit formation, physical appearance, and financial commitment weren’t just frequently discussed, they were highly valued by the community. For trainers or fitness club management, strategies emphasizing consistent habits, concrete goals, and finding genuinely enjoyable activities might prove more effective for clients than those focused mainly on health benefits.

The study also showcases social media’s potential as a research tool. Though traditional methods remain important, analyzing social media conversations captures more natural perspectives. As people increasingly share their experiences online, these platforms offer rich insights into human behavior.

In a world where sedentary lifestyles keep expanding, understanding what truly drives people to exercise becomes increasingly vital.

“It’s an astonishing phenomenon: science tells us that if we put just over two hours a week into physical activity, we can prevent 30% of diseases, improve our quality of life, and extend our lifespan; and yet, less than a quarter of the population actually does this. Why? What have we failed to see?” asks Gepner. “While we all wish our loved one’s good health on their birthday, a wish of ‘good workouts’ is quite rare… But there is a way to be healthy – by exercising. That’s why it’s crucial to understand what really motivates people to engage in physical activity and what helps them stick with it.”

The bottom line? The most effective exercise routine isn’t necessarily the scientifically optimal one — it’s the one you’ll actually do consistently. As one Redditor summed it up: “Do something fun for exercise. For example, I love basketball so I play basketball as an exercise but I still enjoy it and it doesn’t even seem like work.”

Paper Summary

Methodology

The researchers used a clever multi-step process to mine Reddit for insights about exercise motivation. They started by searching for keywords like “motivation,” “exercise,” and “sport,” initially finding 59 subreddits. They narrowed this down by removing smaller communities (under 100,000 users), non-English groups, and forums not focused on exercise motivation. This left them with six popular subreddits: three fitness-specific (r/bodyweightfitness, r/crossfit, r/Fitness) and three general advice communities (r/askMen, r/askWomen, r/askReddit).

Using Reddit’s API, they pulled comments containing motivation and exercise terms. To prevent any single prolific user from skewing results, they included only one randomly selected comment per user. After filtering out comments with just emojis, links, non-English text, or single-word responses, they had 1,577 unique comments to analyze.

Their analysis combined machine learning with human expertise in a five-step process. First, they used natural language processing to identify potential topic clusters. Then exercise science experts reviewed these clusters, suggested topic titles, and validated the categorization by independently reviewing samples. The remaining comments were automatically sorted into these topics. A second expert evaluation assessed this classification’s accuracy, with five graduate-level exercise physiology students reviewing random samples. Finally, they evaluated their classifier’s reliability using statistical metrics and expert agreement measures.

Results

The analysis revealed ten distinct topics falling into two categories: reasons to start exercising and ways to stick with it. Among motivations, physical appearance dominated at 24%, followed by physical health (19%) and mental health (17%). For adherence strategies, habit formation was the clear leader at 30%, with goal setting (14%), enjoyable activities (12%), socializing (10%), media use (9%), app monitoring (3%), and financial commitment (3%) completing the list.

The researchers dug deeper by examining how topics connected. They found physical and mental health frequently appeared together, as did strategies like app tracking and goal setting. The pre/during COVID comparison showed a notable shift from appearance toward health-focused motivations during the pandemic. When they examined which topics got the most upvotes, habit formation, physical appearance, and financial commitment received particularly positive reception from the Reddit community.

Limitations

Despite its fresh approach, the study has important limitations. The researchers lacked detailed demographic information about the commenters beyond Reddit’s general user statistics, which skew toward young, male, higher-income Americans. This makes it difficult to connect specific motivations with particular population groups.

The research questions were also relatively narrow, focusing mainly on identifying motivations and strategies rather than exploring effectiveness or adherence outcomes. And like all self-reported information, especially on anonymous platforms, there’s no way to verify how truthfully users described their experiences.

The researchers’ “data-driven” approach allowed considerable discretion during data selection and filtering, potentially introducing selection bias. They acknowledged this limitation and suggested future studies could use more standardized methods for topic classification. Additionally, the initial topic categorization was done by just one reviewer without a formal content analysis process, which might have influenced how certain topics were classified.

Discussion and Takeaways

The findings partially align with previous research while offering fresh perspectives. The three main motivations (appearance, physical health, mental health) match categories in established questionnaires like the Exercise Motivation Measurement scale, supporting both the study’s approach and traditional assessment methods.

However, the results diverge in some areas. Reddit comments rarely mentioned personal and social motivations like challenge, enjoyment, social recognition, and group belonging that often appear in standard questionnaires. This difference might stem from Reddit’s public, anonymous nature, where users may be less likely to discuss personal motivations openly.

The findings have practical applications for promoting physical activity. Knowing that habit formation, goal setting, and enjoyable activities are the most commonly mentioned strategies could shape more effective interventions. Programs that help people build consistent routines, set concrete goals, and find activities they genuinely enjoy might achieve better long-term adherence than those focused primarily on health benefits.

More broadly, the study shows the value of social media as a research tool. While traditional methods remain essential, analyzing social media captures more natural, unfiltered perspectives. This approach expands research possibilities and provides deeper insights into how people think and behave in real-world contexts.

How to avoid exercise burnout and still build muscle, according to an expert

How to avoid exercise burnout and still build muscle, according to an expert

Many of us have experienced the overwhelming feeling of mental and physical exhaustion that comes with exercise burnout. When you push yourself too hard without sufficient rest and recovery, it ultimately becomes counterproductive to your fitness goals, and your energy will tank along with your motivation. Not only that, your performance will suffer when you overtrain and under-recover, and you’re left sinking further into the couch, wondering how you’ll lift that next weight, swim that next lap, or run that next mile.

With a combo of the right nutrition, rest, recovery, and lowering your training intensity, you can get back on track. To learn more about avoiding burnout and torching fat while sculpting muscle for men, I asked certified personal trainer and Vice President of Education for Body Fit Training, Steve Stonehouse, to share some of his vast knowledge on the subject. With decades of experience in fitness education, fitness programming, and personal training, Steve Stonehouse developed an in-depth knowledge of weight loss, improving body fat composition, building muscle, and the best exercise plans that generate serious results. 

Expert advice on burning fat

The Manual: As the Vice President of Education for Body Fit Training, what are your top tips for burning fat and improving body composition for men? 

Steve Stonehouse: As the programmer and head of education, this is a little cliché, but I go for balance. Not every workout can be this CrossFit type, give it all you’ve got, smoke yourself, and work out — that’s not sustainable. The other end of the spectrum is just walking at a moderate pace for 20 minutes on a treadmill three times a week, because that’s not going to do it either. There’s value in both of those scenarios. 

It’s best to have a session or two each week where the intensity is very high, and you’re testing yourself and pushing yourself closer to your limits. That’s anaerobic exercise, which is 90% intensity or above. It’s fine, safe, and healthy to get there occasionally, but every workout can’t be one of those. Your body isn’t built to train that way; you’re gonna burn out, and you could get injured, or both.

There’s a place for some moderate intensity as well, so if I were focusing on heart rate, I would say in the 80s, so it’s hard but not max effort, and it’s more sustainable. When you’re in that 70 to high 80s range, we categorize that as building aerobic capacity. Overall, I suggest an approach with recovery, moderate intensity, and then high intensity every now and again to test yourself. 

The best cardio for fat loss

TM: How does cardio help with fat loss, and what types of cardio do you recommend?

Steve Stonehouse: I’m a big fan of high-intensity cardio. Sometimes, people think if some is good, more is probably better, but more isn’t always better. If I were putting a program together for six days a week, I’d have three days as some type of cardio-driven day, and three of those days I would have some version of resistance training. Maybe some days are heavier, and other days are a little lighter with higher rep targets and less rest.

Of those three cardio days, I’d recommend that one of them be a high-intensity max effort type HIIT session. Another could be hard with a heart rate in the 80s, but not max effort. That third cardio day could be more metabolic conditioning, like kettlebell swings, sled pushes, rower, or SkiErg, and things like that.

Ramping up muscle growth

TM: What types of exercise are the most effective for ramping up muscle growth?

Steve Stonehouse: We’re moving into a great space right now in fitness, and it seems like every 10 or 15 years, there’s this new movement. CrossFit first popped up and led the charge for metabolic conditioning and no days off. It’s the idea that if you still feel good at the end of a workout, you didn’t train hard enough. I think we’re phasing out of that and into wanting to lift heavy again. People who wouldn’t have touched a barbell ten years ago are lifting heavy now.

Keep in mind that heavy is a relative term. You can get stronger with some lighter dumbbells, but there are limits to that. A blend is nice, but you do need to include those times when you’re lifting heavy and challenging yourself at a low rep target.

Say, I’m going to do barbell deadlifts for five reps. If I can do eight, then that weight is too light. It’s intended to be a weight that you can’t get 15 reps of. There are advantages to lifting heavy with low-rep targets and longer rest times. For example, we’re going to do four sets of five reps of barbell deadlifts with two minutes of rest in between sets. If you can do more than five or six reps, that weight is too light. There’s a lot of value in lifting heavy.

TM: We know it’s probably difficult to choose, but what are your top three favorite fat-burning, muscle-building exercises right now?

Steve Stonehouse:

  • Barbell Zercher squat
  • Barbell deadlift
  • Flat barbell bench press

TM: How often should you work out to build muscle?

Steve Stonehouse: For the heavy session with five or six reps and longer rest periods, you could have a day each week that’s primarily focused on upper-body heavy strength training. Then, you could split it up and have another day that’s primarily focused on the lower body. You could do that, so you’re not in the gym for two hours; it’s more like a reasonable 45 or 50 minutes. If you were feeling ambitious, you could get a third one in toward the end of the week and have a bit of a mixed session where there’s not as much volume, but you have upper-body and lower-body focus. 

With that type of heavy volume, you’re going to need a decent amount of time to rest. So, if I were doing a heavy bench press today, I probably wouldn’t do that again until next week — same thing with squats, deadlifts, or any larger main lifts.

Incorporating sufficient rest days and progressive overload

TM: Are rest days important for the best results?

Steve Stonehouse: Yes. Rest and recovery are two different things. A recovery session would include a bit of activity, but at a lower intensity. Recovery is restoring to a natural, healthy state, and rest is inactivity. 

TM: With resistance training, do you recommend incorporating progressive overload, where you gradually increase the weights over time to develop muscle strength and mass?Steve Stonehouse: 100%. We do strength training regularly at BFT. We have a portion of our performance app, and you can enter your five-rep max. On different days, the performance app tells you how much weight you should be lifting on that day to appropriately follow that progressive overload model.

Skip the 10,000 Steps: The One Exercise That Matches a Full Day of Walking, according to a Fitness Coach

On Instagram, Zarina Manaenkova advised taking short intervals of squats could deliver the same impact as a full day of walking. “Ten squats instead of 10 thousand steps,” Zarina’s post read, referencing a study that equated ten squats every 45 minutes with 10,000 steps. Manaenkova explained the science behind her claim, stating, “When your muscles actively contract, they produce very important compounds that influence your brain, metabolism, and even your fat-burning processes. Meanwhile, a simple walk does not have this effect. So, if you want to stay young, squat.”
