Title is pretty bad. The actual claim is "exercising twice a week may help preserve memory and thinking skills in people with mild cognitive impairment." Meanwhile things like https://www.frontiersin.org/articles/10.3389/fpsyg.2016.00642/full https://www.frontiersin.org/articles/10.3389/fpsyg.2016.0064... directly contradict the title. That is, exercise et al. are good to help cognitive functioning but have no prediction on cognitive performance.
