For many years, international recommendations for physical activity have suggested that “150 minutes of moderate or 75 minutes of vigorous exercise per week” is enough to maintain health. These guidelines mainly come from general studies targeting the population as a whole, regardless of gender or individual characteristics.

However, a recent study significantly changes the landscape — it shows that men may require much more exercise to achieve the same cardiovascular benefits that women get with less activity.

This raises the question: Are the “one-size-fits-all” guidelines realistic? And how should a man structure his workouts to truly protect his heart? In this article, we’ll explore the latest data and how to translate it into practical action.

What Research Says — Men and Heart Health: How Much Exercise Is Needed

A large 2025 study analyzing data from over 85,000 participants (both men and women) using activity trackers reached striking conclusions: to reduce the risk of coronary heart disease (CHD) by ~30%, women need about 250 minutes per week of moderate to vigorous exercise, while men need around 530 minutes per week — almost 9 hours.

If a man “sticks” to the usual 150 minutes per week, the same data show his CHD risk reduction is only ~17%, compared to ~22% for women.

This difference does not appear to be due solely to total physical activity — i.e., the time spent — but also to biological and physiological differences between genders, such as hormones, muscle fiber composition, metabolism, and more.

In practice, this means that if you are a man and want to truly reduce your risk of heart disease, the “general” recommendations may not be sufficient.

Why This Difference Exists — Possible Explanations

Researchers suggest several physiological differences that may explain the results:

• Hormonal differences: In women, estrogen has a well-known cardioprotective effect.
• Muscle fiber composition and metabolism: Men often have more “fast-twitch” muscle fibers, which may be better suited for strength and power, but not for sustained cardiovascular protection needed to prevent CHD.
• Differences in cardiovascular response: How exercise affects blood vessels, lipid profiles, blood pressure, insulin resistance, etc., likely differs between men and women.

For all these reasons, the “one-size-fits-all” prescription — 150 minutes per week — increasingly seems inadequate, especially if the goal is long-term heart health.

What This Means in Practice — A Guide for Men

• Realistic Goal: 8–9 Hours of Activity per Week

To genuinely target cardiovascular disease prevention, aim for ~500–550 minutes per week of moderate to vigorous activity (brisk walking, running, cycling, swimming, intense cardio).

• Combination of Cardio + Strength + Daily Activity

The most effective approach is not just running 2–3 times per week, but:

• Cardiovascular exercise (running, cycling, back-and-forth walking)
• Strength training / resistance exercises — for muscle support and overall metabolism
• Incorporate “short” activities into daily life: walking for commuting, taking stairs, standing breaks if sitting for long periods, general mobility

• Frequency & Consistency: Make It a Routine

Two to three sporadic workouts aren’t enough — better results come from a consistent program 4–6 times per week with variety. Plan your week with the goal of total weekly time, not just “I’ll work out today.”

• Pay Attention to Recovery & Lifestyle

Sleep, nutrition, avoiding prolonged sitting, and stress management all significantly impact the cardiovascular benefits of exercise. Exercise is not a “magic bullet” by itself but part of an overall healthy lifestyle.

Other Studies & Benefits Beyond the Heart

• Another study shows that individuals with good fitness levels have a lower resting heart rate, which translates into “fewer total heartbeats per day,” potentially extending the “lifespan of the heart.”
• Regular exercise also helps reduce risk factors such as high blood pressure, poor cholesterol, and insulin resistance — all strong predictors of heart disease.

This means that the benefits of exercise are not limited to “active minutes” alone but extend to overall health, metabolism, endurance, and longevity.

Precautions & Practical Advice — What Not to Do

• The “530 minutes per week” recommendation is not a guarantee — it is an average. Not reaching it doesn’t mean you gain no benefit. Every extra activity counts.
• If you have underlying health issues (heart disease, high blood pressure, injuries, etc.), consult a doctor before starting an intensive routine.
• Overtraining or insufficient recovery can negate benefits — balance and consistency are more important than extreme measures.

Recent scientific evidence clearly shows that, for men, heart health requires more than the old “standard” weekly exercise guidelines. Prevention is not a matter of “a couple of workouts a week” — it’s a routine, a commitment, and a serious life choice.

If you view exercise as an investment — for your heart, endurance, and life — adding 5–10 extra hours of activity per week, along with strength training, a healthy lifestyle, and a consistent routine, is not a burden. It’s security.

Better heart health doesn’t come from magic solutions — it comes from consistency, realism, and the decision to care about what happens “years down the line.”
