Maybe not For most of the past century, exercise benefits were thought to fade when people stopped working out. > You use it or lose it ## Training history matters Muscle and liver cells store memories from past training to improve endurance and blood sugar control. > Muscle and liver cells store memories from every training session ## Muscle memory works Retrained mice grew bigger muscles with stronger energy production matching demand. > Mice who retrained grew bigger muscles ## Liver cells help too Liver cells release enzymes to feed muscle more efficiently after retraining. > Liver cells also store exercise memory and uses it to feed muscle more efficiently ## Exercise passes to offspring Maternal and paternal exercise can protect offspring from poor blood sugar and weight gain for a year. > Three to four weeks of maternal and paternal endurance exercise can have lasting effects ## Every cell remembers Skin stem cells and fat cells also keep exercise records that persist after weight loss. > Skin stem cells can keep a record of inflammation ## Exercise memory is real Cells store exercise memories regardless of how much or how little someone trains. > Every cell in the body remembers exercise ## What this means for you Your past workouts may help you regain fitness faster after a break from exercise. > People who have trained before can get fit again faster ## Not a reason to skip gym Past training doesn't replace current exercise but helps maintain gains. > None of these findings are evidence for skipping the gym ## The record stays Your cells hold a record of every workout that plays out when you return to exercise. > Somewhere, deep in your cells, there is a record waiting to be replayed ## What happens next Better understanding of exercise memory could improve guidelines for those who can't exercise consistently. > Better understanding of how cells learn and remember exercise could help improve exercise guidelines ## Why it matters Exercise memory helps people regain fitness faster after breaks from training. > People who have trained before can get fit again faster ## The science behind it Researchers used an ON-OFF-ON training protocol in mice to study exercise memory. > Our team used an ON-OFF-ON exercise training protocol in mice ## Key takeaway Muscle and liver cells retain exercise memories that improve endurance, blood sugar control and slow weight regain after inactivity.
