Fitness Through the Ages

Over the past century, activity levels and exercise habits have shifted dramatically, with each generation experiencing a unique set of societal, economic, and technological influences that shaped their approach to physical fitness. These shifts in physical activity have had a profound impact on mobility, health, and longevity. From the naturally active Silent Generation to the tech-savvy Gen Z, every cohort has seen how changing lifestyles have affected their physical well-being over time. Let’s take a deeper look at these changes and how they influenced each generation’s mobility and long-term health outcomes, as well as their exercise habits.

The Silent Generation (Born ~1925–1945)

For the Silent Generation, physical activity was a natural part of their everyday life. They didn’t engage in formal exercise routines, but rather maintained fitness through manual labor, farming, and chores. This generation’s physical activity was tied to survival and productivity, with most people walking or biking to work or school, and engaging in physically demanding jobs.

Many of these individuals maintained good mobility well into old age, thanks to their active lifestyles. However, they often lacked access to modern healthcare, especially in their younger years.  There was also less awareness or understanding of preventive exercise. This generation experienced the wear and tear of labor-intensive work, leading to joint problems and musculoskeletal issues later in life. But their early years of consistent movement contributed to higher levels of endurance and mobility compared to future generations. Life expectancy for this group was lower compared to today, but their physical activity likely contributed to relatively better heart health and resilience into old age.

The Baby Boomers (Born ~1946–1964)

The Baby Boomers grew up in an era when television was becoming commonplace and most people had access to vehicles.  They grew up running and playing in their neighborhoods as more people moved to the suburbs.  It was a badge of honor to obtain a drivers license and have the freedom and flexibility of your first car.  This generation experienced jobs becoming more sedentary, with many working in office environments, so they compensated by engaging in recreational exercise.  This was the first generation to consciously engage in exercise for health, largely influenced by the rise of fitness movements in the 1970s and 80s. Many took up jogging, aerobics, and gym memberships, driven by a cultural shift toward physical fitness.

The fitness boom helped Boomers maintain mobility and stave off many of the chronic conditions associated with aging. Regular exercise, such as aerobic workouts and strength training, improved cardiovascular health, muscular strength, and flexibility, all of which contributed to better mobility as they aged. However, as Boomers have aged, many have seen a rise in conditions like arthritis, obesity, and diabetes—partly because their working lives were more sedentary. Still, their early years of natural activity and their later embrace of fitness helped extend their life expectancy, as they had access to both better healthcare and greater awareness of exercise’s role in health. Those who continue to maintain active lifestyles into retirement are generally healthier, with fewer mobility issues compared to previous generations.

Generation X (Born ~1965–1980)

Generation X is often seen as a transitional generation between the Boomers’ fitness obsession and Millennials’ holistic approach to wellness. Gen Xers grew up with a mix of both outdoor play and the rise of video games and computer technology, which began to encourage more sedentary pastimes. Many in this generation embraced the fitness trends of their era, including bodybuilding, aerobics, and gym workouts, but they also faced the challenge of balancing this with desk-bound jobs.

Gen X’s fitness habits have varied significantly, leading to mixed health outcomes. Those who participated in regular physical activity, whether through gym memberships or sports, tend to have better mobility as they age. However, the increasing prevalence of sedentary office work has led to a rise in conditions like obesity, back pain, and cardiovascular diseases among those who did not prioritize exercise. For many Gen Xers, maintaining mobility into their later years has become a challenge, especially as the digital revolution has encouraged more screen time and less movement. Those who have continued to stay active through weight training and cardiovascular workouts have generally preserved their muscular strength and flexibility, which are key to mobility, good health and longevity.

Millennials (Born ~1981–1996)

Millennials were the first generation to grow up in the digital age.  They were heavily influenced by both sedentary jobs and pastimes, thanks to technology, and the rise of boutique fitness and wellness culture. While many spent more time on screens than previous generations, they also embraced fitness as a lifestyle. This generation saw the rise of yoga, Pilates, CrossFit, and fitness apps, reflecting their interest in maintaining both physical and mental well-being. Their focus on wellness extended beyond just exercise, incorporating healthy eating, mindfulness, and mental health into their daily routines.

Millennials have experienced mixed outcomes regarding mobility and long-term health. While many have remained active through gym memberships, fitness classes, and digital fitness platforms, the generation also faces unprecedented levels of stress and burnout, which can hinder overall health. Those who engage in regular exercise, especially weight-bearing activities like strength training, are likely to maintain better bone density, joint health, and mobility as they age. However, the sedentary nature of their work and reliance on technology have led to concerns about posture-related issues, back pain, and obesity. The wellness movement embraced by Millennials has likely contributed to increased longevity, but for some, the disconnect between screen time and physical activity may pose a challenge to maintaining health later in life.

Generation Z (Born ~1997–2012)

Generation Z is the first to grow up entirely in a world of smartphones, social media, and digital entertainment. This has led to a more sedentary lifestyle overall, with less time spent in physical activities and more time spent on screens. However, Gen Z is highly aware of the importance of health and fitness, influenced by fitness influencers and the accessibility of online workout content. Virtual fitness, fitness apps, and wearable technology have made exercise more approachable, even if it’s done from home.

Gen Z’s relationship with physical activity is complex. While they are aware of the importance of staying active, many struggle to integrate sufficient movement into their lives, especially with the rise of remote work and schooling. This generation is at greater risk of early health and wellness issues if sedentary habits continue, including back pain, poor posture, and cardiovascular problems. However, the generation’s focus on wellness, mental health, and exercise trends could counteract some of these risks if they manage to strike a balance between screen time and physical activity. Given their access to fitness technology and health information, they may be able to course-correct and prioritize fitness for greater longevity and mobility in the future.

Generational Fitness Trends: Impact on Health and Longevity

Across generations, the shift in fitness trends has had a direct impact on health, mobility, and longevity. The Silent Generation and Boomers, who were active by necessity or embraced structured fitness later in life, have seen better mobility into old age, although joint issues and musculoskeletal wear are common. For Gen X and Millennials, the rise of sedentary lifestyles due to office jobs and technology has posed challenges to mobility, with many now focusing on exercise to mitigate these effects. Millennials’ holistic wellness focus has likely extended their potential for longevity, although their sedentary work habits may still create long-term health issues. Gen Z’s future mobility and longevity will likely depend on their ability to balance technology use with physical activity. Their focus on mental health and wellness is promising, but their reliance on screens poses a risk to their overall health outcomes if left unchecked.

Final Thoughts

As fitness trends have shifted across generations, so too have their impacts on mobility, health, and longevity. Early generations benefited from active lifestyles that kept them moving, while more recent generations have had to grapple with the sedentary nature of modern life. Each generation has found its own way to incorporate physical activity into daily life, whether through manual labor, jogging, gym workouts, or virtual fitness apps.

The challenge for future generations will be to prioritize movement in a world increasingly dominated by screens and sedentary work. However, with access to fitness technology, wellness information, and a growing awareness of the importance of holistic health, there is potential for every generation to maintain better mobility, health, and longevity as time goes on.
