30 to 60 Minutes of Lifting a Week Tracks With 10 to 20 Percent Lower Mortality. Past Two Hours, the Curve Flattens and Even Bends Back.
Ask ten men how much strength training they need to live longer and you will hear everything from zero to six days a week. The best available answer comes from pooled cohort data, and it is surprisingly modest. In 2022, Momma and colleagues combined 16 prospective studies in the British Journal of Sports Medicine and found that adults who did muscle-strengthening activity had 10 to 17 percent lower risk of dying from any cause, and of developing heart disease, cancer and type 2 diabetes. The steepest part of the benefit sat between 30 and 60 minutes a week. Beyond that, the curve flattened, and at around two hours or more the all-cause mortality benefit appeared to shrink. This article walks through what those studies measured, why the curve might bend, how much of it could be confounding, and what a reasonable weekly plan looks like for a man over 35 who wants the largest share of the benefit for the least time.
Key Takeaways: What the Research Shows About Strength Training and Lifespan
A 2022 meta-analysis of 16 prospective cohort studies by Momma and colleagues in the British Journal of Sports Medicine linked muscle-strengthening activity to roughly 10 to 17 percent lower risk of all-cause mortality, cardiovascular disease, total cancer, type 2 diabetes and lung cancer. The largest reduction in all-cause, cardiovascular and cancer mortality in the Momma analysis appeared at about 30 to 60 minutes of muscle-strengthening activity per week, a J-shaped pattern rather than a straight line. Adults who combined muscle-strengthening activity with aerobic activity had about 40 percent lower all-cause mortality, 46 percent lower cardiovascular mortality and 28 percent lower cancer mortality than adults who did neither, according to the same meta-analysis. In an English and Scottish survey cohort of 80,306 adults analysed by Stamatakis and colleagues in 2018, any strength-promoting exercise was linked to 23 percent lower all-cause mortality and 31 percent lower cancer mortality, and bodyweight exercise counted as much as gym training. All of these findings come from observational studies with self-reported exercise, so they show association, not proof that lifting itself extends life. US and WHO guidelines recommend muscle-strengthening activity on two or more days a week covering the major muscle groups, and only about one in four American adults meets both the strength and aerobic targets.
How much strength training per week is linked to the lowest risk of death?
About 30 to 60 minutes of muscle-strengthening activity per week was linked to the lowest risk of death in the largest pooled analysis to date. Momma and colleagues, publishing in the British Journal of Sports Medicine in 2022, ran a dose-response analysis across the cohort studies that recorded weekly time. For all-cause mortality, cardiovascular disease and total cancer, the risk reduction peaked at roughly 10 to 20 percent in that 30 to 60 minute window. Thirty to sixty minutes a week is a small amount of training. Two sessions of 20 to 30 minutes, or three sessions of 15 to 20 minutes, fall inside the range. The finding matters for men who avoid lifting because they assume it requires an hour a day in a gym; the cohort data does not support that assumption. Type 2 diabetes followed a slightly different shape in the Momma analysis. Diabetes risk fell steeply up to about 60 minutes a week and then continued to fall more gradually at higher volumes, without the upturn seen for mortality.
Lower Risk Across Five Outcomes

The reported range across outcomes was about 10 to 17 percent. These are observational associations based on self-reported exercise.
Does more strength training than one hour a week add any benefit?
In the Momma 2022 meta-analysis, strength training beyond about 60 minutes a week did not add further reduction in all-cause, cardiovascular or cancer mortality, and the all-cause benefit appeared to shrink at higher volumes. Around 130 to 140 minutes a week, the estimated all-cause mortality benefit moved back toward no difference compared with doing none. The upturn at high volumes is the most quoted and the least certain part of the curve. Far fewer participants reported more than two hours of weekly strength training, so the confidence intervals at the top of the range are wide. The authors themselves described the evidence at higher volumes as uncertain and called for more research rather than advising men to cap their training. Several explanations for the bend have been proposed. Men who lift for many hours a week may differ in ways the cohorts did not capture, such as anabolic steroid use, very high body weight, or heavy competitive training. Some researchers have pointed to arterial stiffness, which rises acutely after very heavy lifting in some laboratory studies, though no cohort has shown that mechanism explains the mortality pattern. The cautious reading is that the benefit plateaus around an hour a week, and the data above two hours is too thin to call either harmful or helpful.
A J-Shaped Curve: The Benefit Peaks Early

The shaded band marks the 30 to 60 minute window with the largest risk reduction. Values are an illustrative reconstruction, not the published point estimates, and the right side of the curve rests on few participants with wide confidence intervals.
Is lifting weights better combined with cardio?
Yes, combining strength training with aerobic exercise is linked to considerably lower mortality than either activity alone. In the Momma 2022 meta-analysis, adults who did both had about 40 percent lower all-cause mortality, 46 percent lower cardiovascular mortality and 28 percent lower cancer mortality compared with adults who did neither. A separate analysis of the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial cohort, published by Gorzelitz and colleagues in Medicine and Science in Sports and Exercise in 2022, followed close to 100,000 adults with an average age of about 71. Weightlifting on its own was associated with 9 to 22 percent lower all-cause mortality depending on frequency. Older adults who met the aerobic guideline and also lifted once or twice a week had 41 to 47 percent lower mortality than those who did neither. The combined effect is not simply the two benefits stacked. Cardiorespiratory fitness and muscle strength track different parts of physiology. Aerobic training mainly improves heart output, capillary density and mitochondrial capacity, while resistance training mainly preserves muscle mass, bone density, insulin-sensitive tissue and the ability to recover from falls and illness. A man who only does one is leaving a separate set of risk factors untouched.

Do bodyweight exercises count as strength training for longevity?
Bodyweight exercises appear to count as much as gym-based lifting in the mortality data. Stamatakis and colleagues, writing in the American Journal of Epidemiology in 2018, pooled the Health Survey for England and the Scottish Health Survey, covering 80,306 adults. Any strength-promoting exercise was linked to 23 percent lower all-cause mortality and 31 percent lower cancer mortality. Bodyweight exercises done without equipment, such as push-ups, sit-ups and squats, showed associations similar to those for gym-based training. The same Stamatakis analysis found no clear link between strength exercise alone and cardiovascular mortality, which differs from the Momma meta-analysis. That disagreement is a useful reminder that individual cohorts measure exercise in different ways, often through a single questionnaire at baseline, and that confidence intervals for specific causes of death are wide. For a man who travels or trains at home, the practical point is simple. The cohort evidence does not require barbells, machines or a gym membership. What the studies captured was regular effort against resistance, and a bodyweight routine done twice a week meets that description.
80,306 Adults: Bodyweight Training Counted Too
Percentage lower mortality linked to any strength-promoting exercise in the Health Survey for England and Scottish Health Survey, analysed by Stamatakis and colleagues in the American Journal of Epidemiology in 2018. Bodyweight exercise showed associations similar to gym training. Cardiovascular mortality showed no clear association with strength exercise alone in this cohort.
Does weightlifting lower heart attack and stroke risk independently of running or cycling?
One large cohort suggests weightlifting lowers cardiovascular events independently of aerobic exercise. Liu and colleagues, publishing in Medicine and Science in Sports and Exercise in 2019, followed 12,591 participants from the Aerobics Center Longitudinal Study in Dallas, all of whom had a clinical exam including a treadmill test. Lifting weights for less than one hour a week was associated with 40 to 70 percent lower risk of heart attack, stroke or cardiovascular death, after accounting for aerobic activity. In the Liu study, spending more than one hour a week lifting did not add further cardiovascular protection, which fits the plateau seen in the Momma meta-analysis. Frequency mattered less than simply doing some. Participants who lifted once a week showed lower risk than those who did not lift at all. The Aerobics Center cohort is mostly white, well educated and relatively fit, so the absolute effect may be smaller in other groups. The value of the Liu study is that it had treadmill-measured fitness, which lets researchers separate the effect of lifting from the effect of being aerobically fit, a common weakness in questionnaire-only cohorts.
How much of the link between lifting and longevity is real cause and effect?
Some of the link between strength training and longevity is almost certainly confounding, and nobody knows exactly how much. Every study in the Momma meta-analysis was observational. Exercise was self-reported, usually once, at the start of follow-up. Men who lift tend to smoke less, eat better, have higher incomes and see doctors more often, and statistical adjustment never removes those differences completely. Reverse causation is another problem. Men who are already developing heart failure, cancer or frailty often stop lifting before they are diagnosed, which makes non-lifters look sicker than lifting alone would explain. Better studies exclude deaths in the first few years of follow-up to reduce this bias, but not all cohorts in the meta-analysis did so. Randomized evidence supports the mechanisms even though it cannot test mortality directly. Controlled trials consistently show that resistance training increases lean mass, improves insulin sensitivity, lowers blood pressure modestly and increases bone mineral density. Westcott, reviewing the trial literature in Current Sports Medicine Reports in 2012, summarised about 10 weeks of resistance training as adding roughly 1.4 kg of lean weight and removing 1.8 kg of fat, with a resting metabolic rate rise of about 7 percent. Those changes plausibly lower risk. They do not prove a 15 percent mortality reduction.
What should a weekly strength plan look like for a man over 35?
A weekly strength plan built around the cohort data for a man over 35 can be two sessions of 20 to 30 minutes, hitting the major muscle groups, on non-consecutive days. That schedule lands inside the 30 to 60 minute window where the Momma meta-analysis found the largest mortality reduction, and it matches the US Physical Activity Guidelines and WHO recommendation of muscle-strengthening activity on two or more days a week. A sensible session covers a lower-body push such as squats or leg press, a hip hinge such as a deadlift variation or hip thrust, an upper-body push such as push-ups or bench press, and an upper-body pull such as rows or pull-downs. Two to three hard sets per movement, each taken to within a few repetitions of failure, is enough to drive strength gains in untrained and moderately trained men, based on minimal-dose training reviews. Men who want more muscle, not just the longevity association, can train more. Schoenfeld and colleagues reported in the Journal of Sports Sciences in 2017 that roughly 10 or more weekly sets per muscle group produced greater hypertrophy than lower volumes. Higher volume is a reasonable choice for physique or performance goals. The cohort data simply suggests the mortality signal is mostly captured well before that point. Aerobic work should sit alongside the strength plan. The guideline is 150 to 300 minutes of moderate or 75 to 150 minutes of vigorous aerobic activity per week, and the combined-exercise data from the Momma and Gorzelitz analyses shows the largest mortality differences when both targets are met.
The Cohorts Behind the Numbers
Approximate participant counts in the single cohorts discussed in this article. The Momma meta-analysis pooled 16 studies, several of them far larger. All are observational, and only the Aerobics Center Longitudinal Study measured fitness on a treadmill rather than by questionnaire.
Can GLP-1 users or men on peptides skip strength training?
No, men losing weight on GLP-1 medications have a stronger reason to strength train, not a weaker one. In the STEP 1 trial of semaglutide 2.4 mg, a DEXA substudy found that lean mass accounted for roughly 40 percent of total weight lost. Resistance training is the best-studied way to preserve muscle during a calorie deficit, and preserving muscle is part of what the cohort data links to longer survival. Growth hormone secretagogues and other peptides marketed for body composition do not substitute for training either. Tesamorelin, for example, reduces visceral fat in specific populations, but no peptide has shown the broad mortality associations seen with regular resistance exercise. For a man using GLP-1 microdosing or a peptide protocol, two short strength sessions a week remain the foundation rather than an optional extra.
