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.

Still finding it too cold to exercise outside? 7 best advanced home workouts to boost muscle and endurance

It might be starting to feel more spring-like outside (last weekend, we thank you), but March is still pretty cold at times, with more than its fair share of inclement weather. So, if you’re still leaning towards living room workouts rather than lacing your trainers up for a chilly run, we get it.

While there are a myriad of advantages to getting your movement in from home (convenience, cost and time, to name just a few), it’s easy to write off a home workout as too easy. And all too often, they’re targeted at us getting back into movement post injury, rehab or baby. Which got us thinking: is it really possible to do an advanced workout from home?

How to get rid of flabby arms?

Per the fitness coach, the one exercise that can help you get rid of flabby arms is dumbbell bicep curls with a twist. The video begins with Patrick sharing tips on how to do the exercise and its variation. He suggested starting with light dumbbells, weighing approximately 7-10 pounds and focusing on perfect form – “Keep your elbows locked at the side and move slowly (3 seconds up and 3 seconds down).”

“As you progress, increase the weight to challenge your muscles. You should feel the burn. If you want variety, you can also try hammer curls, but this time, use the 21’s Strategy – 7 reps lower half, 7 reps upper half, and then 7 full range – 21 in total. Superset this with tricep dips or extensions to tone up the back of those arms, and then you will say goodbye to that flab in no time,” he suggested.

How to do 21’s for bigger biceps?

The coach also suggested how to do the 21’s Strategy correctly to up your game and feel the burn. “If you’ve ever tried 21’s for biceps and didn’t feel the burn…you probably did them wrong,” he wrote. Here’s how to do them properly:

The Breakdown

21 reps total > 3 phases > No ego lifting

  • First 7 reps – Lower half of the curl (bottom to halfway)
  • Next 7 reps – Upper half of the curl (halfway to the top)
  • Final 7 reps – Full range of motion (all the way up and down)

Tips to keep in mind:

  • Use control, don’t just swing the weight.
  • Keep elbows locked, no cheating with shoulders.
  • Choose a lighter weight than your usual curl, or you’ll burn out fast.
  • Do this exercise 1-2 times a week, especially if you work out at home.

Remembering Red Lerille

Remembering Red Lerille

“Hello, goodbye, and toilet paper.”

According to Lloyd “Red” Lerille, owner of Red Lerille’s Health & Racquet Club in Lafayette, Louisiana, those are the three most important things in business. Considering his successful 63 years in the health and fitness industry and his induction into the HFA’s inaugural Hall of Fame class, it’s hard to argue with his wisdom.

From Humble Beginnings to Industry Pioneer

Red’s journey began as a three-time high school wrestling champion in New Orleans. Inspired by his uncle Harold, Red saw fitness as transformative. In 1953, he trained at Ajax, Joe Gold’s New Orleans gym, honing his skills in bodybuilding and business. He began competing in contests and won the Mr. America title in 1960, before serving a stint in the Navy.

“When Red got out of the Navy, Mike Stansbury had him manage his gym in Lafayette,” recalls Red’s daughter Kackie Lerille. “He came with a bag of clothes and a unicycle. All he ever wanted was to own a little gym like that.”

With a $200 loan from his father, Red and his wife, Emma, opened Red Lerille’s Health & Racquet Club, a 3,500-square-foot gym in Lafayette, in 1963.

“The first club was small. We joke it was the size of a racquetball court,” says Kackie. “It was really a labor of love. My dad built his own equipment because you couldn’t buy any.”

He eventually moved to his current location in 1965, upgrading to 4,000 square feet. But, as with bodybuilding, staying small was never part of the plan. In 1968, Red made his first addition, adding a vinyl pool. There was no going back.

“Red decided early on he was going to reinvest in the club and do something new every month,” says Mark Lerille, Red’s son, who now manages the property. “It didn’t matter if it was something small or something that would take time to finish, he was going to do something every month.”

It’s a tradition that continues to this day.
