The Shocking Exercise Secret That Could Add 10 Years to Your Life—Are You Doing It Wrong?

Exercise is often lauded as one of the cornerstones of a long and healthy life, alongside a nutritious diet and effective stress management. However, determining the exact exercise regimen that best suits an individual can be a daunting task. A new study published in BMJ Medicine offers valuable insights into this puzzle, particularly highlighting the benefits of varying exercise types for longevity.

Researchers analyzed data from over 100,000 people who reported their physical activity over a span of nearly 30 years. This extensive study leveraged information from the Nurses’ Health Study and the Health Professionals Follow-Up Study, focusing on healthy participants who documented their exercise habits—specifically the types of physical activity engaged in and the duration—every few years. The scientists then compared this data against mortality rates from various causes, including heart disease, cancer, and respiratory illnesses, to ascertain which exercise patterns were linked to a longer life.

As expected, individuals who exercised more frequently had a significantly lower risk of death—ranging from 4% to 17%—depending on the type of activity performed, compared to those who were less active. However, a more intriguing finding emerged when the data was broken down by exercise type. Individuals who engaged in a combination of exercise types experienced an additional 19% reduction in the risk of death compared to those who followed a consistent regimen.

“Keeping up the total amount of activity is still the most important,” explains Yang Hu, a research scientist at Harvard’s T.H. Chan School of Public Health and one of the study's authors. “But on top of that, maybe you can try to diversify the types of activities you do by trying different things, which may gain you additional benefit.”

Among the various exercises studied, vigorously walking was associated with the most significant reduction in early death risk, showing a 17% decrease compared to less active individuals. Other activities that followed included running (13% reduction), climbing stairs (10%), and resistance training (9%). While swimming was not linked to measurable benefits in this research, Hu suggests that definitions of swimming varied widely—from leisurely floating to intense laps—which could affect the results.

The benefits of mixing different types of exercise are becoming clearer, with prior studies highlighting how varied physical activities can promote heart health, respiratory function, and lower risks of hypertension. Strength training, in particular, is essential for maintaining muscle mass and preventing falls, especially in older adults. Hu notes that individual exercises often reach a plateau in terms of health benefits, beyond which additional activity may not yield significant improvements. Thus, combining different forms of exercise can optimize health benefits and further reduce the risk of early death.

“We speculate that the variety of physical activities means that people are able to take advantage of two or even more dimensions of exercise,” Hu adds. “We want to make the case that it’s possible that the mix of aerobic and resistance or strength training has complementary benefits.”

As such, for Americans who strive to improve their health and longevity, this study underscores the importance of not only maintaining an adequate level of physical activity but also diversifying the types of exercise undertaken. Whether it's through brisk walking, running, or strength training, incorporating a variety of physical activities may be the key to unlocking additional health benefits and enhancing one's quality of life.
