Story at-a-glance

A study from Brazil's State University of Campinas found twice-weekly weight training for six months preserved brain regions vulnerable to Alzheimer's in older adults with mild cognitive impairment
In this research, five of the 22 people in the resistance training group improved enough to no longer meet clinical criteria for cognitive impairment
Exercise protects the brain through multiple mechanisms. It stimulates growth factors like BDNF, reduces inflammation, improves cerebral blood flow, and regulates stress hormones that contribute to cognitive decline
For optimal longevity benefits, research suggests limiting strength training to 40 to 60 minutes weekly; exceeding 130 to 140 minutes may reverse health gains and even shorten your life
Mind-body exercises like yoga and tai chi also benefit brain health. They lower cortisol, reduce anxiety, and improve executive function, attention, and processing speed
