When you hear the word athlete, what comes to mind? Olympic sprinters? Professional football players? Marathon runners who voluntarily wake up at 4:00 a.m. for "fun"? Good news—you don't have to own a gold medal, a six-pack, or neon compression socks to be an athlete. Your inner athlete is already there. It may just be hiding under a cozy blanket with a bowl of popcorn.

Aging is a natural biological process—not a disease. While growing older is inevitable, many of the physical and mental changes commonly associated with aging are not. Fatigue, loss of strength, poor sleep, chronic inflammation, weight gain, cognitive decline, and reduced vitality are often influenced more by lifestyle than by chronological age.
