There’s a growing segment of our population that is extremely fit. They spend hours each day training for marathons, ultra-marathons, Ironman triathlons and hundred-mile bicycle rides. Their bodies take a beating and rely on electrolyte drinks, energy gels and nutrition bars to get to the finish line and aide in recovery. But it’s still a very tiny percentage of the overall population and much smaller than the number of people who actually consume those products.

I’ve interviewed experts over the years who all agree that, unless you’re working out at a high intensity for more than 90 minutes, you don’t need those things. The typical American diet provides enough sodium, potassium, carbohydrates and other nutrients for the casual exerciser. So keep this in mind as you look to cut calories and expenditures this holiday season.

And watch for my story next week on a handful of other fitness products that are a waste of your time and money.
