We're fit when we're young because we play all the time. Basketball, football, baseball, going crazy at the school dance were all part of our everyday lives, so we could eat anything we wanted and never gained an ounce because we burned it all up. We never even had to think about things like fitness, calorie counting and working out. Somewhere between 32 and 36 years-old reality hit like a brick sandwich and our weight ballooned when we were asleep. Most of us try to fit in regular exercise, but between raising children, going to work, and owning a home, something has gotta give. It's going to be our exercise regimen every single time.
