New Research Suggests 560 Minutes of Weekly Exercise Needed for Optimal Heart Health

A landmark study published in the British Journal of Sports Medicine on May 19, 2026, indicates that the long-standing global recommendation of 150 minutes of moderate-intensity exercise per week may be insufficient for those seeking maximum protection against cardiovascular disease. While the current guidelines, supported by the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), provide a foundational level of health benefit, this new research suggests that tripling that amount—reaching between 560 and 610 minutes of activity per week—could lead to a significantly more substantial reduction in the risk of heart attacks and strokes. The findings advocate for a shift from a generalized "one-size-fits-all" approach toward personalized fitness targets that account for an individual’s baseline cardiorespiratory health.

The Gap Between Current Guidelines and Optimal Protection

For decades, public health officials have promoted 150 minutes of moderate-to-vigorous physical activity (MVPA) as the "gold standard" for maintaining health. This metric was designed to be achievable for the general population, providing a realistic goal to combat sedentary lifestyles. However, data from a 2024 CDC report highlights a significant compliance gap, revealing that only 47 percent of American adults currently meet this 150-minute threshold.

The newly released study, led by researchers including Ziheng Ning of Macao Polytechnic University, suggests that while the 150-minute mark is a vital "minimum effective threshold," it does not represent the peak of preventative care. According to the research, individuals who adhered to the 150-minute guideline saw a nine percent reduction in the risk of cardiovascular events. While statistically significant, this figure pales in comparison to the 30 percent risk reduction observed in participants who logged approximately nine to ten hours of exercise weekly.

Study Methodology and the UK Biobank Dataset

The research team conducted an extensive longitudinal analysis using data from the UK Biobank, one of the world’s most comprehensive biomedical databases. The study tracked 17,088 participants between 2013 and 2015, with a follow-up period spanning nearly eight years. The average age of the cohort was 57, a demographic particularly susceptible to the onset of cardiovascular issues.

To ensure accuracy, the study moved beyond self-reported data, which is often subject to recall bias. Instead, participants wore wrist-mounted activity trackers for seven consecutive days to record precise movement patterns. Additionally, researchers administered cycling tests to estimate each participant’s VO2 max—the maximum rate at which the body consumes oxygen during intense exertion. This measurement served as the primary indicator of cardiorespiratory fitness (CRF). Over the course of the eight-year follow-up, the researchers recorded ,233 major cardiovascular events, including myocardial infarctions and strokes, allowing them to correlate activity levels with long-term health outcomes.

The 560-Minute Threshold: A Statistical Breakdown

The most striking finding of the study is the volume of exercise required to achieve "substantial" protection, defined as a risk reduction exceeding 30 percent. The data indicates that participants needed to engage in 560 to 610 minutes of moderate-to-vigorous exercise per week to reach this level of safety.

On a daily basis, this translates to roughly 80 to 87 minutes of activity. Only 12 percent of the study participants managed to hit these high-volume targets. The researchers also identified a "fitness gap" regarding how much exercise different people need. Individuals with lower initial fitness levels (lower VO2 max) required an additional 30 to 50 minutes of exercise per week to achieve the same cardiovascular benefits as those who were already highly fit. For example, a person with low fitness might need 370 minutes of exercise to achieve a 20 percent risk reduction, whereas a highly fit individual could achieve that same reduction with 340 minutes.

Expert Reactions and the Nuance of "Minimum" vs. "Optimal"

Medical professionals have been quick to clarify that these findings do not render the 150-minute guideline obsolete, but rather categorize it as a baseline. Ziheng Ning, the study’s lead scientist, emphasized that 150 minutes remains a critical starting point because it is realistic and offers clear benefits for cognition, sleep, and mental health. "What our findings suggest is that 150 minutes per week may function more as a minimum effective threshold, rather than the dose associated with substantial cardiovascular risk reduction," Ning stated.

Dr. Kevin Shah, a cardiologist based in Long Beach, California, noted that the study underscores the importance of baseline fitness. He suggests that the amount of effort required to maintain or improve heart health is inherently tied to a person’s current physiological state. Dr. Bert Mandelbaum, a sports medicine physician in Santa Monica, added that for those who have already trained extensively, the heart, lungs, and brain are more "efficient," but the need for consistent, high-volume movement remains a constant for peak longevity.

Dr. Tamanna Singh, Director of the Sports Cardiology Center at Cleveland Clinic, pointed out that the challenge lies in the body’s ability to adapt. She advocates for varying exercise routines to ensure the cardiovascular system is "continuously challenged to become more efficient, aerobically and mechanically."

Practical Challenges and Lifestyle Integration

The prospect of finding nine hours a week for exercise—nearly double the current average for even active Americans—presents a significant logistical challenge. However, the researchers and cardiologists involved in the study suggest that this total does not necessarily require nine hours in a gym.

"People hear ‘560 minutes’ and imagine they must suddenly become endurance athletes," Ning explained. Instead, the study suggests that the accumulation of "lifestyle activity" is key. This includes:

• Active commuting (cycling or brisk walking to work).
• Utilizing stairs instead of elevators.
• Engaging in recreational sports or hiking on weekends.
• Incorporating "exercise snacks"—short bursts of high-intensity movement—throughout the day.

Dr. Singh noted that adding resistance or intensity to existing routines, such as jogging intervals during a walk or adding incline to a treadmill session, can help the body reach the necessary efficiency levels more effectively than steady-state, low-intensity movement alone.

Study Limitations and Demographic Considerations

While the study provides compelling evidence for higher exercise volumes, it is not without limitations. The research is observational, meaning it identifies a correlation between high exercise volume and heart health but does not strictly prove that one causes the other. Other factors, such as diet, genetics, and socioeconomic status, may also play roles in the cardiovascular outcomes of the high-activity group.

Furthermore, the study population was 96 percent white, which limits the generalizability of the findings to more diverse populations. Cardiorespiratory fitness was estimated rather than measured through direct laboratory oxygen consumption tests, and the researchers did not account for sedentary time or very light physical activity, which some experts believe could also impact heart health. Finally, the "healthy volunteer effect" suggests that people who participate in the UK Biobank may be more health-conscious than the general public, potentially skewing the results toward a fitter-than-average demographic.

Broader Implications for Public Health Policy

The implications of this study could lead to a significant shift in how doctors prescribe exercise. If the goal of a patient is specifically to mitigate a strong family history of heart disease, a physician might move away from the 150-minute recommendation and toward a more aggressive 500+ minute "prescription."

This research also highlights the need for structural changes in urban planning and workplace culture. If optimal heart health requires 80 to 90 minutes of daily movement, the traditional sedentary office environment becomes a primary obstacle to public health. Policies that encourage active transport, standing desks, and workplace fitness breaks may become essential components of cardiovascular disease prevention.

Ultimately, the study redefines exercise not as a pass/fail threshold, but as a continuum. While any movement is better than none, and 150 minutes provides a solid foundation, the path to "substantial" heart protection appears to require a much larger commitment of time and effort than previously thought. As personalized medicine continues to evolve, the integration of VO2 max testing and tailored activity targets may become the new standard in preventative cardiology.
