Lifting Just 3 Hours Per Week Makes You Live Longer

In this new study made up of 4,800 American men and women ages 20-69, researchers analyzed the relationship between how many hours per week people strength trained and their biological age measured by telomere length.1

Quick Takeaways:

  • Telomeres are protective caps at the ends of our DNA.

    • Every time our cells divide, a portion of telomere is lost until eventually the cell can no longer replicate itself to survive.

    • Telomere length is a validated measure of how much time we have left. It is currently the best tool in determining our true biological age.

  • In this study, people who resistance trained had significantly longer telomeres than those who didn’t (including those who did other forms of exercise).

  • Telomere length was predicted by number of hours per week lifting.

“The difference in cellular aging was substantial… an hour of strength training 3x week was associated with 7.8 years less of biological aging.”

Throw some iron around like your life depends on it!
