Key Highlights:
- A recent study from Brigham and Women’s Hospital indicates that both step-count and time-based exercise goals yield favorable health outcomes.

- Emphasizing individual preferences in choosing exercise goals may be more beneficial than strictly adhering to one method of measurement.
Introduction
The debate over the most effective way to measure physical activity—steps or minutes—has garnered significant attention in recent years, especially as technology supports fitness tracking. With the rise of smartwatches and fitness apps, the convenience of quantifying exercise in terms of steps has shifted the conventional focus from time spent exercising. In light of this trend, a pivotal study conducted by researchers at Brigham and Women’s Hospital seeks to clarify whether step-based goals or time-based exercise regimens produce superior health outcomes. The findings, published in JAMA Internal Medicine, underscore the critical link between physical activity and cardiovascular health while simultaneously presenting a compelling case for accommodating individual preferences in exercise goals.
Understanding the Study's Foundation
The research centered around the Women’s Health Study, enrolling 14,399 women aged 62 and older who were free from cardiovascular disease and cancer. Between 2011 and 2015, participants wore specialized devices to monitor their physical activity levels for seven consecutive days. This methodology allowed researchers to collect detailed data on both moderate-to-vigorous physical activity and daily step counts, laying the groundwork for a comprehensive analysis of how these metrics correlate with long-term health outcomes.
The Metrics of Health: Step Counts vs. Time-based Goals
Traditionally, exercise recommendations have emphasized the duration and intensity of physical activity, with guidelines suggesting a minimum of 150 minutes of moderate-to-vigorous exercise weekly. However, with the increasing prominence of step tracking, it became essential to compare these two approaches more closely. The study found that the average participant engaged in 62 minutes of moderate-to-vigorous intensity physical activity weekly and walked an average of 5,183 steps per day.
Key Findings of the Research
The follow-up period of the study extended to an impressive nine years. By the end of this timeframe:
- Approximately 9% of participants had passed away.
- About 4% had developed cardiovascular disease.
Crucially, the study established a direct correlation between higher physical activity levels—measured by either steps or minutes—and a marked reduction in the risk of mortality and heart disease. Notably, the most active participants experienced a risk reduction of 30-40% in relation to their less active counterparts.
Moreover, women in the top three quartiles of physical activity outlived those in the bottom quartile by an average of more than two months, regardless of whether activity was quantified as time or steps.
Examining the Practical Benefits of Each Metric
Both step counts and duration-based approaches offer unique advantages and drawbacks for aspiring individuals. Counting steps can be especially beneficial for those who lead active lifestyles because it encompasses not only structured exercise but also everyday movements—activities less likely to be captured when measuring time. For instance, a senior citizen may accumulate significant daily steps through routine activities, which could factor positively into their overall health.
Conversely, younger individuals may engage in various forms of exercise beyond walking, such as cycling or swimming, making time-based measurements more relevant. In these cases, duration might better capture the intensity and effectiveness of their workout.
The Role of Individual Preferences
Dr. Rikuta Hamaya, the study's lead author, emphasized the importance of aligning physical activity goals with personal preferences. He noted that a one-size-fits-all approach fails to account for the diverse ways in which individuals integrate movement into their lifestyles. Whether one prefers to count steps, minutes, or even engage in different activities, the focus should ultimately be on consistent engagement in physical activity.
The findings suggest that public health guidelines should evolve to reflect this understanding, incorporating step-count recommendations and recognizing the distinct motivations behind why individuals choose particular forms of exercise. Ultimately, the key might not lie in choosing one metric over another but rather in fostering environments that support a variety of engaging activities tailored to individual needs.
Implications for Federal Physical Activity Guidelines
With new federal physical activity guidelines planned for 2028, this study delivers essential insights that could influence how healthcare professionals advise patients on physical activity. Dr. I-Min Lee, a senior author of the research, highlighted the necessity of integrating step targets into existing recommendations, catering to diverse preference profiles. This flexibility will not only promote inclusivity but will also enhance overall public health.
As communities continue to seek ways to increase physical activity levels among citizens, understanding how best to measure and promote healthy movement is more critical than ever. Initiatives that encourage walking through the establishment of pedestrian-friendly environments or dedicated walking programs could inspire greater participation in physical activity and, thus, contribute to improved health outcomes across populations.
Steps to a Healthier Life: Practical Guidance
For those looking to enhance their health through physical activity, consider the following tips:
1. Determine Your Preference
Experiment with both metrics. Try setting a step goal (such as 10,000 steps a day) alongside a time-based goal (like walking for 30 minutes). See what aligns best with your lifestyle and motivation.
2. Incorporate Movement into Daily Life
Find opportunities to integrate more movement into your day. Simple changes, such as taking the stairs instead of the elevator or going for a walking meeting, can help boost daily physical activity.
3. Use Technology to Your Advantage
Take advantage of fitness trackers or mobile applications that suit your monitoring style—whether that’s steps, time, or even heart rate. These tools can provide valuable feedback and motivation.
4. Vary Your Activities
Diversify your activities beyond walking. Engage in sports, swimming, cycling, or even gardening. This diversity prevents boredom and promotes a healthier, well-rounded physical routine.
5. Celebrate Achievements
Recognize your accomplishments, no matter how small. Setting and achieving fitness goals can build self-efficacy and motivate ongoing engagement in physical activity.
FAQ
What is the main finding of the study from Brigham and Women’s Hospital?
The study found that both step-count and time-based exercise goals equally improve health outcomes, extending lifespan and decreasing the risk of cardiovascular disease.
Should I focus on steps or minutes when setting exercise goals?
Both metrics are beneficial, and the best choice depends on personal preference and lifestyle. Aim to select a method that you find more motivating and manageable.
How much physical activity do adults need for optimal health?
Adults should aim for at least 150 minutes of moderate to vigorous physical activity each week or 75 minutes of vigorous activity.
Can I track physical activity without a smartwatch?
Absolutely! While wearables provide valuable data, you can track steps and active minutes manually or through mobile applications that require less technology.
Is walking sufficient for meeting physical activity guidelines?
Yes, walking is a highly effective form of exercise that contributes positively toward meeting physical activity guidelines and improving overall health.
How might future physical activity guidelines change based on this research?
The upcoming guidelines may incorporate step-count targets and emphasize flexible, individualized approaches to physical activity that accommodate diverse lifestyles and preferences.
