A review of studies found that being physically active could increase our lifespan by about two to four years, as a “conservative” guess (some research puts it closer to seven years). Other research found that a combination of exercises is best for longevity. But personal trainer Bruno Pontes, working with fitness app Muscle Booster, stressed the importance of strength training as we age.  “Resistance training is one of the most effective tools to counteract the natural muscle loss that comes with ageing,” he said. One paper found that 90 minutes of strength training a week was linked to up to four years of potential extra life. It has also been associated with a 2.3-year lower brain age. Aside from helping you to battle sarcopenia, or age-related muscle loss, strength training can also decrease your risk of falls, Pontes said. And the Mayo Clinic stated that strength training could “slow and, in many cases, reverse the changes in muscle fibres associated with ageing”.  What at-home exercises should I …
