Can lifting weights actually slow aging? Research suggests so.
A recent U.S. study followed close to 5,000 adults and found a clear pattern: people who consistently did resistance-based exerciseāthink weights or bodyweight movementsātended to have longer telomeres. Telomeres act like protective buffers for your DNA, and as they shorten over time, cellular aging speeds up.
Participants who logged around 90 minutes or more of strength training each week showed telomere lengths that translated to being roughly four years āyoungerā at a biological level compared to nonāstrength trainers.
