Women May Need Less Exercise Than Men to Live Longer: Groundbreaking Study Reveals

A surprising new study reveals that women may only need half the amount of exercise men do to gain the same longevity benefits. This challenges long-standing fitness norms and underscores the need for a more personalized, gender-sensitive approach to physical activity.

As sedentary lifestyles continue to threaten public health, this discovery offers a powerful insight: women can achieve optimal health and longevity with fewer minutes of exercise than previously believed.

What the Research Found

The study, published in the Journal of the American College of Cardiology, analyzed data from over 412,000 adults in the U.S. (55% of them women) collected between 1997 and 2019. Participants self-reported their leisure-time physical activity, allowing researchers to assess its impact on overall and cardiovascular mortality.

Current guidelines recommend at least 150 minutes of moderate exercise per week. However, the study found that women who exercised just 140 minutes per week experienced the same reduction in mortality risk as men who exercised for 300 minutes weekly.

Key Highlights:

• Men who exercised 300 minutes/week reduced their mortality risk by 18%.
• Women who exercised the same amount had a 24% reduced risk.
• Women who exercised only 140 minutes/week still achieved an 18% reduced risk — the same benefit as men with over double the duration.

Additionally, both men and women hit a plateau effect at around 300 minutes/week, where more exercise did not translate to significantly greater benefits.

When it came to strength training, similar patterns emerged: women gained the same longevity benefit from one weekly strength session as men did from three.

Why Women May Respond Differently

One possible explanation lies in physiological differences. According to Dr. Martha Gulati, study co-author and director of preventive cardiology at Cedars-Sinai in Los Angeles, women generally have lower muscle mass, meaning they might derive greater benefit from the same effort. In essence, “a little goes a long way.”

This emphasizes the need for gender-specific fitness guidelines and suggests that exercise efficiency — not just duration — plays a critical role in promoting health and longevity.

How to Add More Movement for Better Longevity

If you’re looking to live longer and feel better, these practical, science-backed tips can help — whether you’re a woman or a man:

1. Set Achievable Goals

Start small. Whether it’s a daily step count or scheduling short workout sessions, realistic goals build consistency and confidence.

2. Try Activities You Enjoy

Not into the gym? No problem. Explore dancing, hiking, swimming, yoga, or team sports. Choose movement that feels fun, not forced.

3. Move Throughout the Day

Daily activity doesn’t have to mean a formal workout. Walk instead of drive, take the stairs, or play with your pets. Even gardening counts.

4. Find Social Motivation

Join a fitness group or find a workout buddy. Community creates accountability and makes staying active more enjoyable.

5. Prioritize Quality Over Quantity

Instead of obsessing over time, focus on effective movement. Mix aerobic activity with strength and flexibility exercises for full-body wellness.

6. Listen to Your Body

Rest matters. Overtraining can backfire, so build in recovery days and adapt based on how your body feels.

Conclusion

This study reshapes how we think about exercise. For women, less can truly be more. With just half the time, they can unlock the same life-extending benefits as men. This not only empowers women to move more efficiently but also challenges fitness norms rooted in a one-size-fits-all mindset.

Whether you’re walking, lifting, or dancing — every movement counts. A small shift in your daily routine can lead to big changes in your long-term health.
