This really surprised me: Walking 40 minutes four times a week changed the size and organization of participants' brains in one year, resulting in the formation of new neurons and larger memory centers, according to a study from the University of Illinois. Walking has also been shown to reduce mild cognitive impairment (a precursor to Alzheimer's and dementia) after six months, reported a study from the University of British Columbia. Participants whose exercise routine entailed walking outside or weight training enjoyed improved memory and learning skills after just six months. Balance and toning exercises like yoga and Pilates, on the other hand, didn't boost their cognitive performance.
