Strength training for longevity has become one of the most important fitness topics in healthy aging and for good reason. While cardio often gets most of the attention for heart health and life span, resistance training may also play an important role in helping adults stay stronger, more capable and healthier as they age
A 2026 study published in the British Journal of Sports Medicinelooked at long-term resistance training, cause-specific mortality and how strength training works alongside aerobic activity. The researchers found that moderate weekly resistance training was associated with lower all-cause mortality, with the lowest risks plateauing around 120 minutes per week
The study also found that combining resistance training with aerobic activity was associated with even lower mortality risk than inadequate aerobic activity with no resistance training
That does not mean strength training is a magic bullet or that lifting weights guarantees a longer life. This was observational research, so it shows associations rather than proving cause and effect
Still, the findings add useful detail to an important question: How much strength training for longevity may be enough to make a meaningful difference?

Strength training for longevity study
The study’s objective was to examine whether resistance training was associated with lower all-cause and cause-specific mortality, whether there was a dose-response relationship, and how resistance training worked together with aerobic activity
Method
Researchers from Harvard’s T.H. Chan School of Public Health, in collaboration with experts from Korea, Brazil and Chile, included participants from three large prospective cohorts: the Health Professionals Follow-up Study from 1992 to 2022, the Nurses’ Health Study from 2002 to 2021 and the Nurses’ Health Study II from 2003 to 2021. Weekly resistance training duration and aerobic exercise duration were assessed using validated questionnaires at baseline and every two years afterward
Researchers used Cox proportional hazard models to estimate hazard ratios and 95 percent confidence intervals
In total, the analysis included 147,374 participants, including 31,540 men and 115,834 women. Participants were followed for up to 30 years, during which researchers documented 35,798 deaths
Results
Compared with no resistance training, 90 to 119 minutes per week of resistance training was associated with a 13 percent lower risk of all-cause mortality, a 19 percent lower risk of cardiovascular mortality and a 27 percent lower risk of neurological disease mortality, after adjusting for aerobic activity. The study authors reported that no additional benefit was observed above 120 minutes per week
The findings for cancer mortality were different. Reduced cancer mortality risk was seen only at lower levels of resistance training: one to 29 minutes per week and 30 to 59 minutes per week
The researchers also looked at resistance training and aerobic activity together. Compared with participants who had inadequate aerobic activity, defined as less than 7.5 metabolic equivalent of task (MET) hours per week, and no resistance training, mortality risk was lowest among participants with both high aerobic activity and resistance training
One example from the abstract was 30 to less than 45 MET-hours per week of aerobic activity plus 60 to 119 minutes per week of resistance training. Mortality risk was also low among those who reached at least 45 MET-hours per week of aerobic activity regardless of resistance-training level
Findings
The main finding is that moderate long-term resistance training was associated with lower all-cause mortality, and the lowest risks plateaued around 120 minutes per week. In plain English, the biggest longevity signal in this study appeared with a moderate amount of strength training, not unlimited lifting time
The study also suggested that strength training and aerobic activity may work best together. Resistance training was associated with further reduced mortality risk across levels of aerobic activity up to around 45 MET-hours per week
Conclusion
The authors concluded that repeated measures of resistance training over up to 30 years of follow-up showed that moderate long-term resistance training was associated with lower all-cause mortality, with the lowest risks plateauing around 120 minutes per week. They also concluded that resistance training was associated with further reduced mortality risk across aerobic activity levels up to around 45 MET-hours per week
What this means for longevity
For people searching for strength training for longevity, the practical takeaway is encouraging: You may not need to spend hours lifting weights every week to support healthy aging
Based on this study abstract, the strongest association for helping lower all-cause, cardiovascular and neurological disease mortality appeared at 90 to 119 minutes of resistance training per week, with no additional mortality benefit observed above 120 minutes per week
That could look like two 45- to 60-minute resistance-training sessions per week, three 30- to 40-minute sessions or another weekly routine that adds up to roughly the same range. The study did not prescribe specific exercises, but resistance training generally includes activities that challenge muscles against resistance, such as lifting weights, using resistance machines, training with resistance bands or performing bodyweight exercises
The other major takeaway is that cardio still matters. In the joint analysis, mortality risk was lowest among people who combined higher aerobic activity with resistance training, and it was also low among those reaching very high aerobic activity levels

In other words, the best longevity-focused fitness routine is probably not strength training instead of cardio. It is strength training plus aerobic activity
Other benefits of strength training
The study published in the British Journal of Sports Medicine (BJSM)focused on mortality outcomes. Additional research has revealed that resistance training may offer several other benefits that matter for healthy aging
1. Helps build and maintain strength
Strength is one of the most important markers of healthy aging because it affects how easily you can perform daily tasks, such as getting out of a chair, climbing stairs, carrying groceries or staying active without help
A meta-analysis published in Ageing Research Reviewsexamined resistance exercise for muscular strength in adults age 50 and older. The review included randomized, controlled trials, as well as randomized and non-randomized studies, and pooled the data using random-effects models
Researchers analyzed multiple common strength outcomes and found that resistance exercise was effective for improving muscular strength in aging adults
That matters because maintaining strength is directly tied to independence. For older adults, strength training is not just about fitness performance. It can help preserve the physical capacity needed for everyday movement and long-term quality of life
2. Can boost bone mineral density
Strength training doesn’t just build muscle; it can also help maintain stronger bones as you age. Because bones adapt to mechanical stress, resistance exercise stimulates bone remodeling by placing controlled loads on the skeleton
Over time, this may help slow age-related bone loss and support bone mineral density
A 2022 systematic review and meta-analysis published in Sports Medicineanalyzed progressive resistance training programs designed to improve both muscle strength and bone mineral density in older adults. After analyzing the available research, the investigators concluded that progressive resistance training produced concurrent improvements in lower-body muscle strength and femur/hip bone mineral density
The analysis also identified characteristics associated with greater bone benefits, suggesting that programs combining resistance training with weight-bearing exercise, using relatively heavy loads and performed consistently over time, were more likely to improve bone mineral density
For healthy aging, these findings are particularly meaningful. Muscle and bone health are closely connected, and preserving both may help support mobility, independence and resilience as people get older
3. Aids metabolic health
Strength training doesn’t just strengthen muscles; it also helps muscles become more effective at taking up and using glucose. Because skeletal muscle is one of the body’s primary sites for glucose disposal, improving muscle quantity and function can have meaningful metabolic benefits
A 2025 systematic review and meta-analysis published in Diabetes Research and Clinical Practice analyzed 19 randomized, controlled trials evaluating resistance exercise training in older adults with type 2 diabetes. The researchers found that resistance training significantly improved glycemic control by lowering both hemoglobin A1c (HbA1c) and fasting blood glucose
Participants also experienced significant improvements in muscle strength, increases in lean body mass, reductions in waist circumference, and improvements in several blood lipid markers, including triglycerides, total cholesterol and LDL cholesterol
The authors concluded that resistance exercise training is an effective strategy for improving metabolic health, body composition and muscular strength in older adults with type 2 diabetes, making it a valuable component of a healthy aging routine
4. Helps reduce fall risk when included in exercise programs
Falls are a major concern for older adults because they can lead to injury, reduced confidence, loss of independence and lower quality of life. Strength training can be especially useful when it is part of a broader program that also challenges balance
An updated systematic review and meta-analysis published in the British Journal of Sports Medicine examined whether exercise prevents falls in older adults. The review updated prior meta-analyses, used random-effects meta-analysis and meta-regression, and searched databases including the Cochrane Library, CINAHL, MEDLINE, EMBASE, PubMed, PEDro and SafetyLit
The authors concluded that exercise as a single intervention can prevent falls in community-dwelling older people. They also found that programs that challenge balance and use a higher exercise dose have larger effects
This is important because strength training for longevity should not be viewed only through the lens of mortality. A longer life is more meaningful when it comes with better mobility, balance and independence
5. Supports healthy body composition
Healthy aging isn’t just about maintaining a healthy body weight; it’s also about preserving muscle while reducing excess body fat. Resistance training is uniquely suited for this because it stimulates muscle growth while also improving overall body composition
A 2023 meta-analysis published in Science Progressevaluated 15 randomized, controlled trials involving 587 adults age 60 and older to determine how resistance training affects body weight and body composition. Compared with control groups, resistance training produced statistically significant improvements in body weight, body fat percentage, fat mass, body mass index and lean body mass
The researchers concluded that resistance training is associated with meaningful improvements in body composition among older adults
These findings are important because body composition often changes with age. Adults naturally tend to lose muscle while gaining body fat over time, and those shifts can negatively affect mobility, metabolic health and physical function
Regular resistance training helps counter many of these age-related changes by supporting lean muscle while improving overall body composition
More ways to support longevity
While strength training appears to be an important component of healthy aging, it’s only one piece of the longevity puzzle. Research consistently shows that a combination of healthy lifestyle habits has the greatest potential to support a longer, healthier life
1. Stay physically active throughout the week
Strength training and aerobic exercise complement one another
The Physical Activity Guidelines for Americans recommend that adults aim for at least 150 minutes of moderate-intensity aerobic activity (or 75 minutes of vigorous activity) each week, along with muscle-strengthening activities involving all major muscle groups on at least two days per week
Rather than choosing between cardio and strength training, consider incorporating both into your routine since the benefits of these exercises include promoting longevity
2. Prioritize a protein-rich diet
Exercise provides the stimulus for building muscle, but adequate protein supplies the amino acids needed for muscle repair and growth
Including high-quality proteintance training, particularly for older adults who are more susceptible to age-related muscle loss
- Fish
- Eggs
- Greek yogurt
- Cottage cheese
- Lean poultry
- Beans and lentils
- Tofu and tempeh
3. Eat plenty of fruits and vegetables
A dietary pattern rich in colorful fruits and vegetables provides vitamins, minerals, fiber and phytochemicals that support overall health
Many longevity-focused eating patterns, including the Mediterranean diet and other longevity-promoting diets, emphasize whole plant foods as dietary staples
4. Get enough sleep
Sleep is when much of the body’s recovery and repair processes occur. Consistently getting seven to nine hours of quality sleep each night supports exercise recovery, metabolic health and overall well-being
5. Manage chronic stress
Long-term stress may negatively affect multiple aspects of health. Finding sustainable stress-management strategies, such as walking, meditation, yoga, spending time outdoors or connecting with friends and family, can support overall wellness
6. Avoid tobacco and limit alcohol
Smoking remains one of the strongest modifiable risk factors for premature death. If you smoke, quitting is one of the most impactful steps you can take to improve your long-term health
Limiting alcohol consumption may also support healthy aging as part of an overall healthy lifestyle
7. Stay consistent
Perhaps the most important lesson from the featured longevity study is that consistency matters more than perfection
The researchers found meaningful associations with relatively modest amounts of weekly strength training. Building a routine you can maintain over months and years is likely to provide greater long-term benefits than an intensive program that’s difficult to sustain
Frequently asked questions
What is strength training for longevity?
Strength training for longevity means using resistance exercise to support healthy aging, physical function and long-term health. In the BJSM study, moderate long-term resistance training was associated with lower all-cause mortality
How much strength training is best for longevity?
In the BJSM study, 90 to 119 minutes per week of resistance training was associated with lower all-cause, cardiovascular and neurological disease mortality compared with no resistance training. The lowest all-cause mortality risks plateaued around 120 minutes per week
Is strength training better than cardio for longevity?
The study does not suggest replacing cardio with strength training. In fact, the lowest mortality risk was seen among participants who combined higher aerobic activity with resistance training
Does lifting weights help you live longer?
This study found that moderate long-term resistance training was associated with lower all-cause mortality, but it does not prove that lifting weights directly causes a longer life. Observational studies show associations, not guaranteed outcomes
Can beginners benefit from strength training?
The BJSM research does not specifically analyze beginners, but its findings suggest that moderate weekly resistance training is associated with longevity-related benefits. Beginners should start gradually, use proper form and build consistency
What counts as resistance training?
The BJSM study refers to resistance training duration but does not list specific exercises. Common forms of resistance training include free weights, machines, resistance bands and bodyweight exercises
How many days per week should I strength train?
The research reports duration, not a specific number of days. A practical way to reach 90 to 119 minutes per week would be two or three sessions spread across the week
Is more than 120 minutes per week bad?
The study does not say more than 120 minutes is harmful. It says no additional mortality benefit was observed above 120 minutes per week in this analysis
Conclusion
- Strength training for longevity is about more than building muscle.
- According to the BJSM study, moderate long-term resistance training was associated with lower all-cause mortality, with the lowest risks plateauing around 120 minutes per week. Compared with no resistance training, 90 to 119 minutes per week was associated with lower all-cause, cardiovascular and neurological disease mortality after adjusting for aerobic activity.
- The best takeaway is not to abandon cardio or overdo strength training. Instead, aim for a balanced routine that includes both aerobic activity and resistance training. Two or three strength sessions per week, paired with regular aerobic movement, may be a realistic and research-supported way to help support healthy aging.
