To achieve maximum fat loss, one should include high-intensity training – in this case, weight training or sprinting for intervals of between 20 and 60 minutes, followed by moderate intensity cardio, or Zone 2 cardio. This allows the first exercise the individual does to be high intensity in which they deplete their stores of glycogen which forces the individual to then use fat for the remainder of the exercise. In the case of this approach, where the person should do it fasted, more body fat will be lost.
