A big study, a significant impact.

**People Who Do Strength Training Live Longer — and Better**
**A consensus is building among experts that both strength training and cardio? are important for longevity.**
**By Rachel Fairbank, The New York Times, Aug. 24, 2022**

**In a new study published in The British Journal of Sports Medicine, researchers found that while doing either aerobic exercise or strength training was associated with a lower risk of dying during the study’s time frame, regularly doing both — one to three hours a week of aerobic exercise and one to two weekly strength training sessions — was associated with an even lower mortality risk....**
**For the study, researchers used National Health Interview Survey data, which followed 416,420 American adults recruited between 1997 and 2014.**
[Now, THAT’s what I call a data set! --W] **...**
**After adjusting for factors such as age, gender, income, education, marital status and whether they had chronic conditions, such as diabetes, heart disease or cancer, researchers found that people who engaged in one hour of moderate to vigorous aerobic activity a week had a 15 percent lower mortality risk. Mortality risk was 27 percent lower for those who did three hours a week. But those who also took part in one to two strength-training sessions per week had an even lower mortality risk — a full 40 percent lower than those who didn’t exercise at all. This was roughly the difference between a nonsmoker and someone with a half-a-pack-a-day habit....**

I like the clear metric: Either a person was alive or dead. Similar results were observed for men and women and for individuals younger and older than 60 years.
Strength training has obvious benefits for the elderly. We have to be able to stand up from a chair, to have enough strength to maintain balance and prevent falls.
I’ve done strength training since age 20. But it’s necessary to be consistent to avoid injury. I hurt my back last weekend doing an exercise I did routinely but skipped for a few weeks. Ouch!
I usually do 2 hours of strength training and 4 hours of aerobic dancing (Zumba) per week. Live instruction is available over Zoom but there are also lots of good, free YouTube videos.
This has Macro impact because of the large numbers and great potential savings on health care.
