What if staying younger wasn’t about expensive treatments or miracle supplements, but something as simple as picking up weights a few times a week? New research suggests exactly that. Scientists now say that consistent strength training, just 2–3 sessions a week, may actually slow biological ageing. The idea sounds almost magical, yet it is grounded in clear science.
Weights Training Slows Biological Ageing
A major long-term study makes this connection even clearer. Researchers tracked 4,814 adults and analysed their weekly exercise patterns. Their findings were impressive. Individuals who completed around 90 minutes of strength training per week showed significantly longer telomeres — the tiny protective caps on our DNA that serve as a reliable marker of biological ageing. Longer telomeres indicate healthier, younger cells. According to the study, these participants had an average of 3.9 years less biological ageing compared with those who did no weight training at all.
More Training, Bigger Impact
The story becomes even more compelling when training time increases. Some interpretations of the data suggest that boosting strength training to around 180 minutes per week, which equals three one-hour sessions, may deliver stronger anti-ageing benefits. At this level, resistance training is associated with up to 8 years of reduced biological age.
