Intro
High intensity interval (intermittent) training (HIIT) is an effective tool for weight loss, and fat metabolism. Weight loss and cardiovascular fitness both respond more favourably to HIIT then long duration cardio. However, just as noted in part 4, the general population has the belief that long distance exercise is the most effective form of cardio and fat loss. It is your job as fitness professional to have an understanding of HIIT training in order to educate and sell the benefits of it to your clients. The main reasoning to this belief is due to the well established understanding that as intensity of training increases, the dependency on carbs for metabolism increases, thus, reducing fat metabolism. This belief is well founded and indeed correct, but people focus too much on the initial fat metabolism and do not understand that as intensity increases, the caloric expenditure increases overall exponentially. This being said, when one does long distance running, they may burn more calories in the moment. But over the next 24 hours, the amount of calories burnt by the HIIT training is shockingly higher. Due to this, the amount of fat metabolised by long distance training is insignificant in comparison to HIIT.
