"Older women who did an hour or two of strength training exercises each week had improved cognitive function a year later, scoring higher on tests of the brain processes responsible for planning and executing tasks, a new study has found.
"Researchers in British Columbia randomly assigned 155 women ages 65 to 75 either to strength training with dumbbells and weight machines once or twice a week, or to a comparison group doing balance and toning exercises.
"A year later, the women who did strength training had improved their performance on tests of so-called executive function by 10.9 percent to 12.6 percent, while those assigned to balance and toning exercises experienced a slight deterioration — 0.5 percent."
Summary: If you don't work very hard, you don't get a significant positive result, you've just wasted your time.
