17 Minutes of Daily Weight Training Linked to Lower Risk of Death From Heart Disease, Dementia

A study published in the British Journal of Sports Medicine found that 17 minutes per day of weight training is associated with a 13% lower risk of all-cause mortality, according to research presented in a Daily Mail report. The same amount of resistance training was linked to a 19% lower risk of death from heart disease and a 27% lower risk of neurological death, primarily dementia.

The study followed 150,000 participants from three long-term Harvard studies over up to 30 years, during which nearly 36,000 died.

Researchers used repeated questionnaires to track weight training and aerobic exercise habits.

Reduced Risk of Heart Disease and Dementia Death

Weight training of 90 to 119 minutes per week, or roughly 17 minutes daily, was associated with a 19% lower risk of dying from heart disease, according to the study.

The same amount of resistance training was tied to a 27% lower risk of neurological death, mostly dementia. Researchers noted that the heart benefits may stem from reduced arterial stiffness over time, though intense lifting temporarily stiffens arteries.

The authors cautioned that reverse causation is possible: people in early dementia stages often become less active before diagnosis, which could influence the findings.

Research indicates that resistance training offers special benefits to the brain not seen with aerobic exercise, particularly in preventing mild cognitive impairment, often a prelude to Alzheimer’s disease, according to an article on Mercola.com [1].

Another study published in GeroScience found that structured resistance training not only prevents brain shrinkage in critical memory regions but also reverses symptoms of mild cognitive impairment [2].

Cancer Death Risk and Weight Training Patterns

The study found that only lower amounts of weight training, specifically one to 59 minutes per week, were associated with reduced cancer death risk, showing a 9 to 12% lower risk. Higher amounts of weight training showed no protective effect against cancer death. [7]

Researchers suggested that heavy training increases insulin-like growth factor 1 (IGF-1), which has been linked to certain cancers. According to the study, doing more than two hours per week of weight training did not provide additional benefit in any category.

Physical inactivity is one of the leading causes of non-communicable diseases such as coronary heart disease, Type 2 diabetes, and cancer, according to the book “Animal Moves” by Darryl Edwards [3]. The book notes that there is a growing body of evidence suggesting a positive association between physical activity and reduced disease risk.

Additive Benefits When Combined With Aerobic Exercise

Aerobic activity alone, at least 2.5 hours per week of moderate exercise or one hour and 25 minutes of vigorous exercise, lowered death risk by 26% to 43%, depending on the amount, according to the study. [7]

The lowest risk of death was seen in participants who combined 30 to 45 MET (metabolic equivalents)-hours of aerobic activity with 60 to 119 minutes of weight training, achieving a 45% lower risk. Even at high aerobic levels, adding weight training appeared to offer some benefit, though at extreme levels the additional effect diminished.

Resistance training boosts strength and muscle mass while upping metabolism and cutting down body fat, according to the book “The A-List Diet” by Fred Pescatore [4].

Researchers stated that the findings suggest a modest amount of weight training and regular aerobic exercise may offer the best protection against early death. A study on resistance training and diabetes risk found that moderate muscle strength can reduce Type 2 diabetes risk, according to an article on NaturalNews.com [5].

Conclusion and Study Limitations

The study relied on self-reported weight training, though repeated measurements over decades help reduce error, researchers said. Participants were mostly white health professionals, so findings may not apply to all populations, the authors noted. Intensity and specific exercises were not measured.

The practical message, according to researchers, is that about 20 minutes of weight training most days, combined with aerobic exercise, may offer meaningful long-term health benefits without requiring hours in the gym. [7]

The findings align with broader evidence that regular resistance training supports cardiovascular and brain health. A Georgia Tech study found that 20 minutes of strength training enhanced long-term memory by about 10%, according to another article on Mercola.com [6].
