No need to tell me twice. I started lifting in 1977, when there was virtually not a single published paper on the benefits of strength training. There was just Arnold. I have been at it ever since, adapting my muscle strengthening and building as I needed to so I could meet the needs of running, cycling, and now martial arts. As I write in my ebook, “there is no such thing as unhealthy muscle.”
After a year, women who strength trained twice a week had “significantly lower” white-matter lesions, suggesting that regular weightlifting boosts brain health (and therefore cognitive health) in the long run. And though the study was conducted on women, Liu-Ambrose says the results are equally relevant for men.
