Many people hit the gym or pound the pavement to improve cardiovascular health, build muscle, and of course, get a rockin’ bod, but working out has above-the-neck benefits, too. For the past decade or so, scientists have pondered how exercising can boost brain function. Regardless of age or fitness level (yup, this includes everyone from mall-walkers to marathoners), studies show that making time for exercise provides some serious mental benefits. Get inspired to exercise by reading up on these unexpected ways that working out can benefit mental health, relationships, and lead to a healthier and happier life overall.
“Telomeres are a good index of cellular aging,” says study author Larry Tucker of Brigham Young University. “In short, because of lifestyle differences, some adults are older biologically than their chronological age, while others are younger. Given the same chronological age, adults who engage in high levels of physical activity have nine years’ less cell aging than sedentary individuals. That is substantial and meaningful.”
Previous studies from her lab have also shown that the exercise is linked to changes in the secretion of stress hormones like epinephrine (a.k.a. adrenaline) and norepinephrine. “Our work has shown that each moderate, relatively short exercise bout exerts regulatory/suppression effects over inflammatory activities of immune cells," says Hong, "and in order to maximize this ‘benefit,’ repeated and regular exercise is recommended. In fact, we have also found that higher physical fitness is associated with better regulation of inflammatory activities of immune cells through stress hormones even among obese individuals.”

Protein and fat loss go hand in hand. This nutrient supports muscle growth and raises your metabolism, making it easier to slim down. It also promotes satiety and reduces hunger, so you'll eat less without even realizing it. The American Journal of Clinical Nutrition states that high-protein diets can positively impact appetite, cardiometabolic risk factors, body weight and other factors.
