Strength Training for 90-120 Minutes Weekly Linked to 13% Lower Death Risk: Landmark 30-Year Study

June 4, 2026 | New Delhi

A groundbreaking 30-year study has revealed that dedicating just 90 to 120 minutes per week to strength training could reduce your risk of death from any cause by 13%, with even greater protective effects against cardiovascular and neurological diseases. The research, published in the British Journal of Sports Medicine, represents one of the most comprehensive examinations of resistance training’s impact on longevity to date.

By tracking nearly 150,000 adults over three decades, international researchers have established a clear link between long-term muscle-strengthening habits and a significantly extended lifespan, providing a definitive roadmap for public health recommendations.

Key Findings That Could Change How We Exercise

Researchers analyzed three decades of data from 147,374 participants (31,540 men and 115,834 women) pulled from three massive cohort studies: the Health Professionals Follow-up Study (1992–2022), the Nurses’ Health Study (2002–2021), and the Nurses’ Health Study II (2003–2021). During the 30-year monitoring period, 35,798 participants passed away, providing the study with exceptional statistical depth.

The data revealed sharp risk reductions across several critical health areas when sticking to a weekly routine:

The Sweet Spot: More Isn’t Always Better

One of the most notable revelations from the study is the presence of a definitive plateau point. The data demonstrates that more time lifting weights does not continuously translate to a longer life.

“No further benefits were observed beyond 120 minutes a week of strength or resistance training,” the researchers reported.

This challenges the common assumption that more exercise always equals better health outcomes. The dose-response relationship was surprisingly nuanced. While 90 to 120 minutes weekly offered the peak protective benefits for your heart and brain, shorter blocks of time (1 to 59 minutes per week) actually proved most effective for lowering cancer mortality.

Combining Strength Training with Aerobic Exercise Delivers Maximum Benefit

While pumping iron or doing bodyweight circuits offers independent survival benefits, the true longevity “super-weapon” is a combined approach. When participants paired muscle-strengthening work with traditional aerobic exercise, the drop in mortality risk was profound:

• Aerobic Exercise Alone (above 7.5 MET hours/week): 26% to 43% lower death risk.

• Strength Training Alone (1–59 minutes/week): 7% to 11% lower death risk.

• Optimal Combined Routine (30–44 MET hours aerobic + 60–119 minutes strength): 45% lower death risk.

• Maximum Combined Routine (45+ MET hours aerobic + any strength training): 53% to 58% lower death risk.

MET hours measure the total energy spent during physical activities over a week. To put this in perspective, 7.5 MET hours equals roughly 150 minutes of brisk walking, while higher MET ranges reflect higher intensity activities like running, swimming, or cycling.

The researchers concluded that adding resistance training further reduced mortality risk across all levels of aerobic activity, heavily reinforcing public guidelines that push for a balanced fitness regimen.

What Counts as Strength Training?

You do not need an expensive gym membership to achieve these results. The study defined strength training broadly, tracking accessible exercises that use either external weight or your own body weight to build muscle:

• Press-ups (push-ups), squats, and lunges

• Free weights and dumbbells

• Resistance machines or Nautilus equipment

• Resistance bands

Expert Commentary: Why This Matters

Dr. I-Min Lee, a professor of epidemiology at the Harvard T.H. Chan School of Public Health who was not involved in the study, explained the underlying biology behind these findings:

“Such exercises improve glucose metabolism, enhance maintenance of a healthy body weight, and help improve cardiovascular risk factors such as blood pressure. All these factors lead to lower risks of cardiovascular disease, cancer, and diabetes, which lowers mortality risk.”

While the benefits of cardiovascular workouts have been well-mapped for decades, the specific long-term impact of resistance training had remained hazy. This 30-year data helps fill a massive knowledge gap in preventive medicine.

Important Context and Study Limitations

Despite the compelling findings, medical experts emphasize looking closely at the limitations of the data:

• Observational Design: This was an observational study. It tracks patterns over time but cannot directly prove a definitive cause-and-effect relationship.

• Recall Bias: Exercise habits were self-reported by participants every two years, leaving room for memory errors.

• Activity Gaps: The data did not explicitly track certain popular muscle-building disciplines like calisthenics or Pilates.

• Missing Specifics: Researchers lacked granular data on individual workout intensities or the precise length of single sessions.

• Demographic Skew: The average age at study entry was 54. Those who did more strength training tended to be younger, weigh less, and maintain healthier overall lifestyles, which could slightly skew results.

What This Means for Your Health Routine

If you are looking to optimize your weekly workout plan based on this evidence, here are the key takeaways:

1. Target 90 to 120 Minutes Weekly: This easily breaks down into manageable blocks—such as 15 to 20 minutes a day, or 30 to 40 minutes three times a week.

2. Do Not Skip Cardio: Pair your lifting with brisk walks, running, or cycling. The combination yields double the survival benefit.

3. Value Quality Over Quantity: There is no need to overexert yourself. Going beyond two hours of lifting a week did not yield extra longevity rewards.

4. Start Small: If you are short on time, even 1 to 59 minutes of strength work per week provides real protection, especially against cancer.

Currently, 74% of the study’s participants hit their aerobic goals, but only 46% picked up weights. This highlights a clear gap where many individuals can make simple, highly effective adjustments to their daily routines.

The Bigger Picture for Public Health

These findings align perfectly with recommendations from the U.S. Centers for Disease Control and Prevention (CDC), which advise adults to engage in muscle-strengthening activities at least two days a week alongside 150 minutes of moderate aerobic activity.

Previous smaller reviews support these conclusions, consistently linking strength training to a 10% to 17% reduction in major chronic illnesses.

While population data provides a clear target, personal fitness must always be tailored. Individual responses vary by age, baseline fitness, and underlying medical conditions. Older adults or those living with chronic illnesses should always consult a physician to tailor a safe, balanced exercise plan that protects their joints and heart.
