ACSM Top Fitness Trends 2026: Wearables Lead Again

Wearable Technology Leads for the Second Consecutive Year

Wearable technology has topped the ACSM fitness trends list before, but the 2026 edition marks a notable milestone: this is the second consecutive year it has held the number-one position, and the data supporting that ranking has reached a scale that few predicted when fitness trackers first appeared in the mid-2010s.

"Nearly half of US adults now own a fitness tracker or smartwatch. That is not a niche technology adoption story anymore. It is a fundamental shift in how people relate to their own physical data."

Cayla McAvoy, PhD, lead author, ACSM Worldwide Survey of Fitness Trends 2026

The figures behind that observation are worth sitting with. When the first Fitbit launched in 2009, the idea that millions of ordinary people would voluntarily monitor their heart rate, sleep cycles, and step counts seemed far-fetched. In 2026, nearly half of American adults own some form of wearable fitness device. That penetration rate exceeds most consumer technology categories that have been available far longer. Wearables have moved from enthusiast gadgets to standard tools in the way that smartphones moved from novelties to necessities, quietly and then all at once.

What has changed in recent years is not just ownership rates but the sophistication of what these devices can do. Today's consumer-grade trackers detect irregular heart rhythms, measure blood oxygen saturation, estimate physiological stress through heart rate variability, and generate personalized recovery recommendations. The gap between what a physician could measure in a clinical setting and what a person can monitor on their wrist has narrowed significantly. For fitness professionals, this creates both an opportunity and a challenge: clients arrive with more data about themselves than ever before, but often without the context to interpret it meaningfully.

Fitness Programs for Older Adults: The 73 Million Opportunity

The second-ranked trend in this year's survey is fitness programming designed specifically for older adults, and the demographic forces behind that ranking are about as straightforward as any in the fitness industry. By 2030, all 73 million baby boomers will be 65 or older. That number represents a structural shift in the population that gyms, trainers, and fitness app developers are only beginning to reckon with.

What makes this trend particularly striking is the behavioral data accompanying the demographic shift. Adults aged 65 and older now visit gyms more frequently than any other age group. That reverses a long-standing assumption that gym culture belonged to younger adults, and it reflects decades of public health messaging about the protective effects of exercise on longevity, cognitive function, and independence. The baby boomer cohort, which came of age during the aerobics revolution of the 1970s and 1980s, has maintained exercise habits through midlife and is now bringing those habits into older adulthood in unprecedented numbers.

The fitness industry response has been to develop programming that addresses the specific physiological needs of this population: balance training to reduce fall risk, low-impact resistance work to counter sarcopenia, flexibility programming to maintain joint range of motion, and social structures that address the isolation that frequently accompanies aging. These are not simply modified versions of mainstream fitness classes; at their best, they represent genuinely specialized programming grounded in exercise science for older physiology.

Exercise for Weight Management Reaches Its Highest-Ever Ranking

The third trend on this year's list, exercise for weight management, has reached its highest-ever ranking in the 20-year history of the survey. Understanding why requires acknowledging a cultural and medical phenomenon that has reshaped conversations about body weight and exercise across the country: the rise of GLP-1 receptor agonist medications.

GLP-1 drugs like semaglutide and tirzepatide have been prescribed to millions of Americans for weight loss since their emergence as obesity treatments. Their effects are significant, but they also create a dynamic that exercise scientists find deeply relevant. Users of these medications typically lose substantial muscle mass alongside fat tissue, which creates a compelling medical rationale for structured resistance and cardiovascular training as a complement to pharmaceutical intervention. People who are losing weight with pharmacological assistance are increasingly being told by their physicians that exercise is not optional but essential to preserving the muscle that will support their long-term health.

This has driven more people into gyms and fitness programs with weight management as an explicit goal, and it has elevated the professional standing of fitness trainers who can work with this population. The convergence of pharmaceutical and exercise-based approaches to weight management is one of the more complex developments in the fitness landscape, touching on medical ethics, insurance coverage, and the meaning of "fitness" as a concept. The ACSM's inclusion of this trend at number three signals the organization's recognition that exercise professionals will increasingly work alongside, rather than separately from, medical weight management programs.

Mobile Exercise Apps: 345 Million Users and Growing

Mobile exercise apps rank fourth this year, and the scale of adoption is remarkable. Across platforms, fitness and exercise applications accumulated approximately 850 million downloads in 2024, and the estimated active user base has reached 345 million people worldwide. These numbers place fitness apps among the most widely used application categories in existence, competing with social media, productivity tools, and entertainment platforms for time and attention.

The democratization argument for fitness apps is compelling. A structured workout program that would have required either a gym membership or a personal trainer a decade ago is now available for free or a few dollars a month on a smartphone. For populations that have historically faced barriers to fitness participation, including lower-income communities, rural residents, and people with time constraints from caregiving or shift work, mobile apps represent a genuine expansion of access. The research on whether app-based exercise is as effective as in-person training is mixed, but the behavioral data on adherence suggests that convenient, personalized guidance, even digital guidance, produces better outcomes than no guidance at all.

Balance, Flow, and Core: The Mindful Middle Ground

The fifth trend, which the ACSM labels balance, flow, and core strength training, represents a category that encompasses yoga, Pilates, tai chi, and the growing world of mobility-focused fitness formats. Its ranking reflects a real shift in how people think about exercise quality versus exercise intensity. The cultural narrative around fitness has long privileged intensity: harder, faster, heavier, longer. That narrative is being complicated by a parallel strand that emphasizes control, proprioception, and the movement quality that underlies sustainable physical practice.

Exercise physiologists have been making this case for years, arguing that most adults would benefit more from improving their movement quality and joint stability than from adding more load or intensity. The popularity of formats like yoga and Pilates, which now collectively claim tens of millions of regular practitioners in the United States alone, suggests that some portion of the exercising public has arrived at the same conclusion through direct experience rather than academic argument. Research published in recent years has documented the benefits of yoga and similar practices not just for flexibility but for balance, cognitive function, and chronic pain management, giving this trend a scientific foundation that goes beyond its wellness-culture appeal.

Exercise for Mental Health: The Deepening Motivation Shift

The sixth-ranked trend deserves particular attention because it reflects something more significant than a fitness industry category: it signals a fundamental shift in why people exercise. The ACSM survey found that 78 percent of people who exercise regularly cite mental and emotional well-being as their primary motivation, ranking it above physical fitness and above appearance. That is a reversal of the motivational hierarchy that has historically driven gym marketing, which has tended to prioritize aesthetic outcomes.

The research supporting exercise as a mental health intervention has strengthened considerably over the past decade. Studies have documented the acute mood-elevating effects of aerobic exercise, the longer-term antidepressant effects of regular resistance training, and the anxiety-reducing properties of low-intensity mindfulness-based movement like yoga and walking. For the approximately one in five American adults who report experiencing a mental health condition in any given year, these findings are clinically significant. Exercise is not a replacement for professional mental health care, but the evidence for its complementary role is substantial enough that the medical and fitness communities are increasingly coordinating around it.

This shift in motivation also has practical implications for how fitness professionals communicate with clients and how gyms design their programming and marketing. If the primary driver of exercise participation is no longer "look better" but "feel better," the language of fitness needs to follow. The industry appears to be responding, if unevenly.

Strength Training and the Gap Between Guidelines and Reality

Traditional strength training ranks seventh this year, and its position on the list is accompanied by a sobering statistic: fewer than 30 percent of American adults currently meet the physical activity guidelines for muscle-strengthening exercise. The guidelines, established by the US Department of Health and Human Services, recommend strength training at least twice per week for all adults. The compliance rate suggests that despite the cultural popularity of strength training, driven in part by social media's embrace of weightlifting content, the practice has not translated into broad population-level behavior change.

The reasons are familiar to exercise scientists: access to equipment, knowledge gaps about safe technique, time constraints, and a lingering cultural association of strength training with a particular body type or gym aesthetic. The fitness industry has responded with programming innovations that attempt to lower these barriers, from resistance training classes that require no equipment to short-format strength workouts designed for home practice. Whether these innovations will move the compliance needle significantly remains to be seen, but the gap between evidence-based recommendations and actual behavior is a persistent challenge that this trend ranking makes visible.

New to the List: Adult Recreation and Sport Clubs

The most culturally interesting new entry to the top 20 this year is adult recreation and sport clubs, which appears at number nine. The category encompasses pickleball leagues, running clubs, cycling clubs, recreational soccer leagues, and the broader infrastructure of organized social exercise. Its arrival reflects a convergence of two separate trends that have been building simultaneously: the explosive popularity of pickleball as a sport, and the emergence of running clubs as a primary social institution for a significant segment of young urban adults.

Pickleball's growth statistics are frequently cited because they are genuinely striking. The sport has added millions of players in the United States over the past three years, with recreational leagues proliferating in parks, gyms, and dedicated facilities at a rate that has surprised even sport industry analysts. Run clubs, meanwhile, have become cultural phenomena in cities including New York, Los Angeles, Chicago, and Austin, serving as social venues that happen to involve exercise rather than exercise venues that happen to be social. The community dimension of these formats is not incidental to their appeal; it is central to it.

Functional Fitness Rounds Out the Top 10

Functional fitness, the practice of training movement patterns that support everyday activities rather than isolating individual muscles for aesthetic or competitive purposes, rounds out the top 10. Its sustained presence on the list reflects the influence of an aging population, whose primary fitness concern is maintaining the ability to carry groceries, climb stairs, get up from the floor, and move through daily life without pain or limitation.

Functional fitness also resonates with a broader philosophical critique of conventional gym training, which has often prioritized appearance-driven goals over movement quality and practical capacity. The growing body of research on the benefits of movement-based training for longevity and injury prevention has given this critique scientific backing that it previously lacked. The trend's durability on the ACSM list suggests it has moved from a contrarian position to a mainstream one, at least among fitness professionals.

What 20 Years of Data Tells Us

The 20th anniversary of the ACSM survey is an appropriate moment to step back from any individual year's rankings and consider what two decades of data actually reveal. The most consistent finding is the industry's responsiveness to technology: wearables, apps, and digital fitness platforms have risen steadily as categories over the survey's history, reflecting the broader integration of technology into everyday health behavior.

The second consistent finding is the growing influence of demographic realities. An aging population has been predictably visible in the survey's results for years, and its prominence in 2026 reflects the same structural forces that are reshaping healthcare, housing, and labor markets. The fitness industry's response to these demographics, specialized programming, accessible formats, and age-appropriate intensity frameworks, represents one of the more genuine adaptations the sector has made.

The third finding is more recent but may be the most consequential: the shift in exercise motivation from appearance-based to wellbeing-based. If the data holds, this represents a cultural realignment in how Americans relate to physical activity, away from punishment and toward care, away from performance and toward function. Whether that shift proves durable is a question worth watching over the next 20 years of surveys.
