Imagine if just five extra minutes of movement each day could significantly extend your life. It sounds almost too good to be true, but recent research suggests this simple shift could have profound implications for your health and longevity. While many of us are familiar with the advice to aim for 10,000 steps daily or 150 minutes of exercise weekly, these goals can feel overwhelming, especially for those who struggle to stay active. But here’s where it gets intriguing: what if the key to a longer, healthier life isn’t about hitting lofty targets, but about making small, manageable changes?
A groundbreaking study published in The Lancet (https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(25)02219-6/abstract) explored this very idea. Instead of focusing on whether people meet ideal exercise benchmarks, researchers asked a deceptively simple question: What happens if individuals move just a little more each day or sit a little less? To answer this, they analyzed data from over 135,000 participants across the United States, Norway, Sweden, and the United Kingdom, examining the impact of modest increases in physical activity and reductions in sedentary time.
I sat down with CNN wellness expert Dr. Leana Wen, an emergency physician and clinical associate professor at George Washington University, to unpack the study’s findings. And this is the part most people miss: even tiny adjustments in daily movement—like adding five minutes of brisk walking or cutting 30 minutes of sitting—could lead to significant reductions in mortality rates when applied across large populations.
CNN: What sets this study apart from other exercise research?
Dr. Leana Wen: This study flips the script by focusing on the power of small changes rather than rigid targets. Instead of asking whether people meet established exercise goals, it explores the population-wide impact of incremental increases in activity and decreases in sedentary behavior. It’s a refreshing perspective that acknowledges the challenges many face in adopting traditional exercise routines.
To dive deeper, the researchers conducted a meta-analysis, combining data from multiple studies. They focused on moderate-to-vigorous physical activity—think activities that get your heart rate up, like brisk walking or dancing—and total sedentary time. The results were eye-opening: even a five-minute daily increase in such activity could prevent about 6% of deaths among the least active individuals, rising to 10% when applied to a broader population. Similarly, reducing sitting time by 30 minutes daily was linked to a 3% to 7% reduction in mortality, depending on the group.
CNN: Does this mean we can ditch the 150-minute weekly exercise goal?
Dr. Wen: Not at all. The study doesn’t undermine existing guidelines but adds a layer of nuance. Traditional advice often emphasizes thresholds, like the CDC’s recommendation of 150 minutes of moderate-intensity exercise weekly. While these targets are evidence-based, they can inadvertently suggest that anything less is insignificant. This research reminds us that the relationship between activity and health isn’t all-or-nothing. Even small increases below these thresholds can yield meaningful benefits, especially for those starting from a sedentary baseline.
But here’s where it gets controversial: Some might argue that promoting smaller goals could discourage people from striving for higher activity levels. However, this study suggests that for many, particularly the least active, these modest changes are not only achievable but potentially life-saving. It’s about meeting people where they are and building momentum from there.
CNN: Who stands to benefit most from this approach?
Dr. Wen: The greatest gains are likely among those who are least active—older adults, individuals with chronic conditions, caregivers, and those with sedentary jobs. For them, adding even a few minutes of movement represents a significant relative increase. From a public health perspective, encouraging these small, realistic changes could have a massive impact, reducing disease and premature death on a large scale.
CNN: What’s a practical first step for someone feeling overwhelmed by exercise advice?
Dr. Wen: Shift your mindset from “exercise” to “movement.” It doesn’t have to be a structured workout—taking the stairs, walking during lunch, or standing while folding laundry all count. The goal is consistency, not perfection. Start small, and let those incremental changes build confidence over time.
The study’s takeaway is both simple and profound: progress doesn’t have to be dramatic to be meaningful. Small, sustainable changes, repeated daily, can add up to significant health benefits for you and your community. So, what’s stopping you from taking that first five-minute step today?
