Regular aerobic exercise has been found to be the most effective anti-aging exercise, according to a new study. Researchers analyzed the effects of various forms of exercise on cellular aging in over 4,800 adults. They found that those who engaged in regular aerobic exercise had longer telomeres, which are protective caps on the ends of chromosomes that shorten as we age. The study suggests that aerobic exercise, such as jogging, swimming, or cycling, can help slow down the aging process and keep cells healthier for longer.
