Strength training for 120 minutes per week is associated with a lower risk of mortality, according to a large new study. The research, published in the British Journal of Sports Medicine, followed 147,374 participants for up to 30 years and found that moderate long-term strength training significantly reduces the risk of death from any cause.
For decades, cardiovascular exercise like running, swimming, and cycling dominated longevity recommendations. But this study adds to a growing body of evidence that resistance training is equally important for living longer and better.
What the Study Found
The observational study used repeated measurements of strength training over a follow-up period of up to 30 years. Researchers found that individuals who engaged in moderate strength training had a notably lower mortality risk compared to those who did not.
The specific figure that emerged was 120 minutes per week—about two hours—as the optimal window for maximizing longevity benefits. This is one of the first studies to provide a precise time recommendation for strength training, moving beyond general advice.
Previous guidelines often suggested vague targets like "strength train twice a week" without specifying duration. This study fills that gap with a concrete number that people can aim for.
Why Strength Training Matters for Longevity
Strength training builds and maintains muscle mass, which naturally declines with age. Muscle mass is crucial for metabolic health, mobility, and preventing falls—a leading cause of injury among older adults.
Beyond muscle, resistance training improves bone density, insulin sensitivity, and cardiovascular health. It also supports mental well-being by reducing symptoms of anxiety and depression.
The study's lead author noted that moderate long-term strength training is key. This means consistency over years, not extreme bouts of exercise. The benefits accumulate gradually, reinforcing the idea that sustainable habits matter most.
How to Incorporate 120 Minutes of Strength Training
Hitting 120 minutes per week may sound daunting, but it breaks down to about 20 minutes per day or four 30-minute sessions. The key is to focus on moderate intensity—you should feel challenged but not exhausted.
Here are practical ways to integrate strength training into your routine:
- Bodyweight exercises: Push-ups, squats, lunges, and planks require no equipment and can be done anywhere.
- Resistance bands: Inexpensive and portable, bands offer a full-body workout.
- Free weights: Dumbbells or kettlebells allow for progressive overload, which is essential for building strength.
- Machines at the gym: If you have access, machines provide guided movements and are great for beginners.
- Daily activities: Carrying groceries, gardening, and climbing stairs count toward strength if done with effort.
Start with two sessions per week and gradually increase duration and intensity. Always prioritize proper form over heavy weights to avoid injury.
Balancing Strength and Cardio
While this study highlights strength training, it doesn't negate the importance of cardiovascular exercise. A balanced routine should include both. The World Health Organization recommends 150–300 minutes of moderate cardio or 75–150 minutes of vigorous cardio per week, plus strength training on two or more days.
Combining both types of exercise offers synergistic benefits: cardio improves heart health and endurance, while strength training supports muscle and bone health. Together, they provide comprehensive protection against chronic disease and early death. The longer history behind the story is traced in Sugar Rationing in Early Life Linked to Lower Dementia Risk.
| Exercise Type | Recommended Weekly Duration | Primary Benefits |
|---|---|---|
| Moderate Strength Training | 120 minutes | Muscle maintenance, bone density, metabolic health |
| Moderate Cardio | 150–300 minutes | Heart health, endurance, weight management |
| Vigorous Cardio | 75–150 minutes | Cardiovascular efficiency, calorie burn |
What This Means for You
If you're not currently strength training, this study is a clear call to action. The 120-minute target is achievable for most people, even with a busy schedule. Start small: aim for 10 minutes of bodyweight exercises three times a week, then build up. The background to this story is set out in HRT Linked to Lower Dementia Risk in Women, Study Finds.

For older adults, strength training is especially critical. It helps preserve independence and reduce frailty. The study's long follow-up period underscores that long-term consistency is what yields results.

FAQ
What is the optimal amount of strength training for longevity?
The study found that 120 minutes per week of moderate strength training is associated with the lowest mortality risk. This equates to about two hours weekly, which can be split into shorter sessions.
Can I do strength training at home without equipment?
Yes, bodyweight exercises like push-ups, squats, lunges, and planks are effective for building strength. You can also use household items like water bottles as weights. Consistency and proper form are more important than equipment.
Is strength training safe for older adults?
Strength training is generally safe and highly beneficial for older adults when done with proper form and appropriate intensity. It helps maintain muscle mass and bone density, reducing fall risk. Consult a doctor before starting.
How does strength training reduce mortality risk?
Strength training improves metabolic health, increases muscle mass, enhances bone density, and supports cardiovascular function. These factors collectively reduce the risk of chronic diseases and premature death.
