A new study from Harvard University suggests just 90 minutes of weekly strength training may be linked to a longer lifespan. While the health benefits of exercise are well-established, the optimal amount and type for longevity have remained a question. The research indicates that incorporating strength training into a fitness routine can contribute to improved health outcomes. Researchers did not specify the intensity of the training required to achieve these benefits, but focused on the time commitment. The study adds to the growing body of evidence supporting the importance of resistance exercise for overall well-being and potentially, increased longevity. Further research may be needed to determine the specific mechanisms behind this correlation.
