Exercise Prompts Changes Down to Your DNA, Study Suggests

The researchers looked at both moderate- and vigorous-intensity physical activity and while both improved cellular function, vigorous exercise did so more significantly. Because exercise can have profoundly different effects from one individual to another, it’s tricky to generalize benefits—unless you’ve recruited identical twins for your study, that is. New research in the journal Scientific Reports looked at how exercise affected 70 pairs of identical twins over a seven-year period. Because...
