Spending 90 to 120 minutes on strength training each week can reduce the risk of early death by up to 30% [1].
These findings suggest that relatively small time commitments to weightlifting may significantly extend life expectancy by combating chronic diseases. This provides a concrete target for individuals seeking to optimize their health through exercise without spending excessive hours in the gym.
Researchers published the study in the British Journal of Sports Medicine [2]. The findings were based on a longitudinal dataset spanning 30 years [3]. The data indicates that consistent strength training, which includes weightlifting and other resistance exercises, is strongly associated with a lower risk of premature death [1].
The study highlights that these benefits are most pronounced when strength training is combined with aerobic exercise. This dual approach helps lower the risk of death from common causes, including heart disease, and Alzheimer’s disease [4].
While many fitness guidelines emphasize cardiovascular health, this research underscores the critical role of muscle maintenance. The 90-to-120-minute window suggests that two sessions of one hour each per week may be sufficient to achieve these longevity gains [1].
By focusing on resistance training, individuals may better protect their metabolic health and cognitive function as they age. The longitudinal nature of the study provides a robust look at how these habits translate into long-term survival outcomes [3].
“90 to 120 minutes of weight training per week can reduce the risk of early death by up to 30%.”
This research shifts the focus from purely aerobic 'cardio' routines to a more balanced approach to longevity. By quantifying the specific time investment required for a 30% risk reduction, the study provides a scalable health intervention that can be integrated into standard public health guidelines to combat age-related decline.
