Cardio Confusion

Many exercisers have heard that if you exercise at a lower intensity for a longer period of time you will burn more fat. This is true, a higher percentage of your calories come from fats versus carbohydrates. But, your still burning fewer overall calories for your time commitment. Now the thinking is that doing intervals (elevating your heart rate as much as possible for several minutes at a time and interspersing those intervals with several minutes of lower-intensity periods) are a better option. Still, there is a need to alternate these high energy sessions with longer, less intensity sessions in order to avoid injury and recover. What you ultimately find in the fitness world are alternatives--variations on a theme--that help confuse your body and make it work harder.
