Exercise advice often says to move more. But new research suggests that how much resistance training you do may also matter, especially when the goal is long-term health rather than athletic performance.
- About 90–119 minutes of weekly resistance training had the strongest longevity association.
- The study included 147,374 adults followed for up to 30 years.
- Lower risks were observed for all-cause, cardiovascular, and neurological mortality.
- More than about two hours weekly was not associated with additional mortality benefits.
- Combining resistance training with aerobic exercise was associated with the lowest mortality risk.
- The findings show associations, not proof that strength training directly prevents death.
What Did the 30-Year Study Find?
The research, published in the British Journal of Sports Medicine in June 2026, analyzed participants from the Health Professionals Follow-Up Study, Nurses’ Health Study, and Nurses’ Health Study II.
Among 147,374 adults, researchers recorded 35,798 deaths during up to 30 years of follow-up. Participants repeatedly reported their resistance and aerobic activity, allowing investigators to examine long-term exercise patterns.

Why 90–119 Minutes Stood Out
The relationship was not simply “more is better.” Compared with no resistance training, 90–119 minutes per week was associated with the lowest overall mortality risk, while researchers found no additional benefit above 120 minutes.
This does not mean longer workouts are useless. Higher volumes can still support muscle growth, strength, sport performance, or physique goals. The finding specifically concerns mortality associations.
| Weekly Resistance Training | Study Finding |
|---|---|
| None | Reference group |
| 1–89 minutes | Lower mortality risk |
| 90–119 minutes | Strongest association with lower mortality |
| 120+ minutes | No additional mortality benefit observed |
What Health Benefits Were Associated?
People completing 90–119 minutes of resistance training weekly had a 13% lower risk of all-cause mortality compared with those reporting none.
The same group had a 19% lower risk of cardiovascular mortality and a 27% lower risk of neurological disease mortality. These figures are associations, not guarantees for individuals. British Journal of Sports Medicine study report
Why Strength Training Matters
Resistance exercise does more than build muscle. It improves strength and physical performance, which become increasingly important for maintaining mobility and independence with age.
Evidence from randomized trials also supports resistance training for improving strength and physical performance in older adults with sarcopenia. A 2023 systematic review and network meta-analysis included 50 randomized trials involving 4,085 participants. Is moderate resistance training adequate for older adults with sarcopenia?
Strength Training Plus Cardio
The study does not suggest replacing walking, cycling, swimming, or other aerobic exercise with weight training. Mortality risk was lowest among participants combining resistance training with higher levels of aerobic activity.
This fits current guidance. The WHO Guidelines on Physical Activity and Sedentary Behaviour recommend 150–300 minutes of moderate aerobic activity weekly, plus muscle-strengthening activity involving major muscle groups on at least two days.
What the Science Says
- Strong: Resistance training is associated with lower mortality in large prospective cohorts.
- Strong: Resistance training improves strength and physical performance.
- Moderate: Combining aerobic and resistance exercise provides broad health benefits.
- Limited for causation: The 2026 mortality study was observational and cannot prove that resistance training caused lower death rates.
The study's large sample, repeated exercise assessments, and long follow-up strengthen its findings. However, self-reported activity and the observational design mean healthier lifestyle patterns may partly explain the associations.
Common Myths
Myth: You need to lift weights for hours.
Fact: The study found no additional mortality benefit above roughly 120 minutes per week.
Myth: Strength training replaces cardio.
Fact: The strongest overall associations appeared when resistance and aerobic exercise were combined.
Myth: More training is always healthier.
Fact: More training may help performance goals, but mortality benefits plateaued around two hours weekly.
Who Should Pay Attention?
Older adults have particular reason to prioritize strength because maintaining muscle function supports mobility, balance, and independence. Beginners can start with bodyweight exercises, resistance bands, machines, or light weights and gradually increase difficulty.
People with significant medical conditions, mobility limitations, or prolonged inactivity should consider professional guidance before beginning vigorous resistance exercise.
Bottom Line
The latest evidence points to a practical target: around 90–119 minutes of resistance training per week was associated with the lowest mortality risk in a large 2026 cohort study, with benefits plateauing around 120 minutes.
That is not a magic number or a prescription. For most adults, the smarter strategy is consistent strength training two or three days per week, combined with regular aerobic activity and gradual progression. The goal is not to train endlessly, but to build a routine you can sustain.
