Exercise Slows Aging Clock in Multiple Organs.

In 2025, Takuji Kawamura and a team from Tohoku University reviewed studies on how exercise affects epigenetic aging, which shows how fast your body ages at the DNA level. They looked at human and animal research, focusing on structured workouts like running or weightlifting, using epigenetic clocks to measure DNA changes in blood, muscles, and other organs.

Structured exercise cut biological age by 2 years in middle-aged women after just 8 weeks of aerobic and strength training. Olympic athletes showed slower epigenetic aging (up to 30% less DNA aging markers) than non-athletes. Benefits extended beyond muscles to the heart, liver, fat, and gut, with higher oxygen uptake in older men linked to 20-25% slower aging.

Do regular aerobic and strength workouts to slow aging in your body’s organs.
