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.
But here’s the most important thing to remember about arm fat: It’s totally normal. So many women have it because, thanks to our higher estrogen levels, we store more fat than men. On average, women carry 6 to 11 percent more body fat than men do, according to Australian research. After all, women need a certain amount of fat to be healthy—a minimum of 12 percent of their total weight, to be exact, should come from essential fat, which is found in your heart, lungs, liver, kidneys, intestines, muscles, and tissues of the central nervous system, according to the National Academy of Sports Medicine.
Exercise has long been correlated with a longer life, but it’s only recently started to become clear why this might be. Studies, like a new one in the journal Preventive Medicine which found that exercise is linked to longer caps at the ends of chromosomes, have helped flesh this out a bit more. These caps, called telomeres, naturally shorten as we age, with each cell division. People who live a long time have telomeres that are in better shape than those who don’t—but there’s a lot we can do to affect the rate at which they shorten over the years. The team behind the new study looked at data from CDC's National Health and Nutrition Examination Survey, and found that for people who exercised regularly, their telomeres were 140 base pairs longer on average than sedentary people's. Which correlates to being years “younger” than their sedentary peers.
If you're ready to move on from classic Bulgarian split squats, Swan's amped-up variation gets your upper body in on the action for a true total-body exercise. "This combination move works your legs, butt, chest, back, arms, and core," she says. "And it not only hits all the major muscle groups—it also lets you work on balance." Give it a shot and you'll see why.
