Fear not, "facercise" isn't having a comeback—the latest workouts are truly effective at slowing the effects of growing older. And as more people become aware of hormone replacement therapy, they will start to realize that high-intensity exercise produces hormones that are the fountain of youth, says Pete McCall, an exercise physiologist for the American Council on Exercise (ACE).
"High-intensity exercise causes the body to release more hormones, such as human growth hormone (HGH) and insulin-like growth factor, that are responsible for increasing lean muscle mass and also have anti-aging benefits," he says. While most forms of exercise are good for your body, high-intensity training seems to offer the biggest turn-back-the-clock bang, so instead of buying pricey HGH injections, focus on two to four workouts of this type of strength or cardio training a week, McCall suggests.
