A growing body of research now suggests that men may need to log more physical activity than women to lower their risk of heart disease. New analyses point to different thresholds of exercise linked to cardiovascular benefits, stirring debate about personalized prevention and how guidelines should reflect sex differences.
Recent findings: Activity thresholds differ by sex
Researchers analyzed large cohorts and tracked cardiovascular events over time. They found that while both sexes benefit from more movement, the volume of activity associated with a meaningful drop in heart disease risk appeared higher in men.

Men required greater minutes of moderate-to-vigorous activity to reach the same proportional risk reduction seen in women.
Key statistics reported
- Women showed significant risk reduction at lower weekly activity levels.
- Men needed additional minutes per week to achieve comparable gains.
- The pattern held after adjusting for age, smoking, weight, and medical history.
How the study measured exercise and heart risk
Investigators used wearable devices and self-reported logs. They focused on moderate-to-vigorous physical activity and total steps per day.
The primary outcome was incidence of major cardiovascular events, including heart attack and stroke. Statistical models controlled for other risk factors.
Strengths and limits of measurement
- Wearables provided objective activity data for many participants.
- Self-report helped capture long-term habits but can be biased.
- Observational design can show association, not definitive causation.
Biological and behavioral explanations for the gap
Several mechanisms could explain why men need more activity to see similar benefits.
- Body composition: Men often have more visceral fat, which raises cardiovascular risk.
- Baseline fitness: Men sometimes start with higher or lower fitness levels that change how additional exercise impacts risk.
- Hormonal differences: Sex hormones influence metabolism, inflammation, and vascular function.
- Health behaviors: Differences in diet, alcohol, and healthcare use may interact with activity effects.
What this means for current exercise guidelines
Most public health guidance recommends 150 minutes of moderate or 75 minutes of vigorous activity weekly.
New evidence suggests that a one-size-fits-all target might underdeliver for some men. Experts debate whether to add sex-specific supplements to existing recommendations.
Practical adjustments clinicians might consider
- Assess baseline risk more precisely before setting activity goals.
- Personalize targets using age, fitness level, and comorbidities.
- Encourage incremental increases rather than abrupt jumps in volume.
Actionable tips to increase cardiovascular protection
Whether male or female, small, consistent changes can yield gains. Below are evidence-based tactics to raise weekly activity safely.
- Aim for daily movement: break 30-minute goals into short sessions.
- Mix aerobic and strength training to improve metabolism and heart health.
- Gradually boost intensity or duration every two weeks.
- Use wearable trackers to monitor progress and stay accountable.
- Consult a healthcare provider before starting high-intensity programs.
Population impact and public health considerations
If men on average need more exercise to cut heart risk, public health campaigns should reflect that nuance.
Targeted messaging can help reduce barriers, such as time constraints or lack of facilities. Employers and cities can promote active transport and workplace wellness.
Research gaps and next steps for science
More randomized trials are needed to test if increasing activity beyond standard levels yields causal benefits for men.
Future studies should explore:
- How intensity versus duration affects risk reduction by sex.
- Interactions with diet, sleep, and medication.
- Long-term adherence strategies and real-world implementation.
