Thanks, Ms. Watson. As a trainer here at Fitness, Inc. one of the most frequent things you're going to be asked about is carbohydrates. Lots of our clients want to know: Why do I need carbohydrates? How much do I need? What happens if I don't get enough? Carbohydrates are a hot topic among athletes, and for good reason. Carbohydrates are important fuel for all athletes, and an inadequate supply will lead to a decrease in performance. But here's a caution: there is a lot of information out there about carbohydrates, but there are also some common misconceptions. We need to make sure you know the right information about carbohydrates so you can do a good job advising your clients. For example, take a look at Mario, Sheila, and Trevor and see if you can determine the correct responses to their questions regarding carbohydrates.
