Every step counts, but a few minutes of intense exercise a day can save lives
The evidence accumulated over the past decades on the health benefits of physical activity and exercise is overwhelming with consistent findings from large prospective cohorts, meta-analyses and international guideline documents demonstrating robust reductions in all-cause mortality and major non communicable diseases.
More recently, the availability of device measured physical activity data has refined these associations, confirming nonlinear dose–response relationships and demonstrating that even small increases in moderate to vigorous physical activity among the least active individuals are associated with meaningful health impact and reductions in mortality risk. A recent study published in The Lancet (2) contributes importantly to this direction by estimating the population-level mortality benefits of modest increases in moderate-to-vigorous physical activity (MVPA) and reductions in sedentary time. Its headline message—that even a 5 minute per day increase in physical activity could prevent a meaningful proportion of deaths—has clear public health appeal. However, careful interpretation is necessary to avoid oversimplification and miscommunication of the underlying physiological and behavioral mechanisms.
The study is robust, methodologically sound, and highly relevant for public health policy. Yet, its findings must be read with appropriate nuance. Specifically, three elements require particular attention: (1) the intensity of physical activity considered, (2) the context of baseline activity levels, and (3) the risk profile of the population analysed. A correct understanding of these factors allows for a balanced message: every step counts, especially for sedentary individuals, but structured exercise remains the most effective strategy for reducing mortality risk and improving long-term health outcomes.

A correct understanding of these factors allows for a balanced message: every step counts, especially for sedentary individuals, but structured exercise remains the most effective strategy for reducing mortality risk and improving long-term health outcomes.
From movement to exercise: intensity, quality and impact
A key element in interpreting these findings concerns the intensity and quality of physical activity. The evidence underlying mortality reduction is primarily linked to moderate-to-vigorous physical activity (MVPA), rather than low-intensity or incidental movement. Activities such as brisk walking, cycling, or jogging generate sufficient physiological stimulus to activate central mechanisms including developing new mitochondria (the cells engines) , improvements in cardiorespiratory fitness, enhanced fat oxidation, and improved blood sugar regulation.
This distinction is essential to avoid misinterpretation: not all movement produce the same biological effect, and therefore the same health benefits and mortality risk reduction. While reducing sedentary time and increasing light activity is beneficial, the most meaningful health outcomes are associated with activity performed at an adequate intensity and accumulated progressively over time. For individuals starting from very low baseline levels, even small increments in MVPA can yield disproportionate benefits. However, these relative gains should not be interpreted as evidence that minimal activity is sufficient in absolute terms. Rather, they highlight the importance of progression from inactivity toward more structured and sustained exercise habits.

Exercise differs from generic physical activity in that it is planned, structured, and goal-oriented, designed specifically to improve physical function and health. This distinction is not semantic—it is physiological. Aerobic exercise (more commonly known as cardio) improves cardiovascular and metabolic efficiency, while resistance training preserves and enhances muscle mass, metabolic health, and functional capacity. Their combination is consistently associated with the most robust and durable health outcomes, including improved body composition, metabolic control, and resilience to age-related decline. These adaptations are difficult to achieve through low-intensity activity alone.
Importantly, recent developments in data-driven approaches to health promotion are helping translate these principles into practice. For example, integrated ecosystems that combine assessment, personalization, and continuous engagement enable the prescription of tailored exercise programmes based on individual profiles, supporting progression from generic activity to more precise and effective interventions.

Such as the AI-driven assessment station Technogym Checkup, which evaluates physical and functional parameters and translate them into individualized exercise prescriptions. Within the Technogym digital ecosystem – combining connected equipment, data tracking, and tailored profiling – these capabilities can be extended beyond initial assessment, enabling continuous monitoring, feedback, and adaptation of exercise programmes. In this way, individualized prescriptions are not static, but evolve dynamically with the user’s progress, supporting long-term behavior change and more effective health outcomes.
A concrete example at population level is the experience of the Wellness Valley in Emilia-Romagna, where a multi-stakeholder approach involving institutions, healthcare systems, and private sector actors has promoted physical exercise a cultural and preventive health lever. This initiative has demonstrated how structured, community-based strategies can successfully increase activity levels, reduce sedentary behaviour, and contribute to measurable improvements in population health outcomes.

A High-Risk Population Perspective
Interventions aimed at the least active segments of the population are likely to yield the greatest absolute benefits. For these individuals, small, achievable increases in MVPA represent a realistic and impactful first step. However, this also means that the magnitude of effect observed in this population cannot be directly extrapolated to already active or athletic populations.
A Balanced Public Health Message
For sedentary individuals, five additional minutes of MVPA may represent a realistic and powerful starting point—a first step toward healthier behaviour patterns. For clinicians and policymakers, this supports incremental, inclusive messaging that meets people where they are.
But have a responsibility to communicate clearly that small steps are a beginning, not the endpoint. The ultimate goal should remain the promotion of prevention though structured, progressive exercise programmes capable of delivering maximal health benefits at an affordable cost and, at the same time, lower the possibility to incur in diseases that would require very expensive medical treatments

From Evidence to Practice: The Experience of the Wellness Foundation
A practical illustration of how these principles can be translated into population-level action is provided by the Wellness Foundation, the non-profit organization founded in 2003 by Nerio Alessandri – Founder and CEO of Technogym – with the aim of promoting a wellness-oriented culture grounded in healthy and active lifestyles. Among its key initiatives, the Wellness Valley represents a territorial, multi-stakeholder ecosystem designed to foster not only higher levels of physical activity, but also a broader cultural shift toward structured exercise, ultimately enhancing the health and quality of life at the population level. Complementing this experience, the Wellness Foundation also develops and supports a range of interventions across different settings – including community-based programmes, schools, workplace initiatives, urban environments, and urban planning strategies – aimed at facilitating access to progressively structured and higher-quality physical activity across diverse populations groups. Taken together, this illustrates how effective public health strategies should not only lower the threshold for entry into physical activity, but also create enabling environments that support progression toward more structured and health-enhancing exercise behaviours.
Conclusion
The Lancet study compellingly demonstrates that small increases in moderate-to-vigorous physical activity can meaningfully reduce mortality risk, particularly among the least active individuals. Every step does indeed count, and even modest changes can have population-wide implications. However, correct interpretation requires acknowledging that the benefits observed are linked to moderate-to-vigorous intensity, non-zero baseline activity levels, and high-risk populations. Importantly, translating this evidence into sustained population impact requires coordinated, multi-setting strategies that create supportive environments and enable individuals to progressively engage in structured, higher-quality physical activity. The final message, therefore, should be both inclusive and aspirational: start by moving more—every step matters—but aim to exercise better. To achieve the greatest improvements in longevity and health, individuals should be encouraged to progress toward ‘precision exercise programmes’ that combine aerobic and resistance training, transforming small behavioural changes into lifelong health investments.
