Beginner athletes often struggle with under-fueling their workouts, particularly when taking on a new endurance endeavor like a triathlon or a half marathon. A common misconception of beginner athletes is that they have to be "competitive" or "elite" to need to replenish their body like experienced athletes. Also, beginners often have weight loss goals, leading them to reduce calories before, during or after workouts, which does not promote weight loss or enjoyment in exercise. As a result of not getting enough of the right nutrients at the right time, beginners fatigue early during exercise, both mentally and physically.
