Include Intervals in Your Weight Loss Workout
Intervals are much more effective than traditional steady-pace cardio in your weight loss workout because they increase the overall intensity output of the workout. Intervals allow you to achieve a greater total energy expenditure and burn more total calories both during and after the session.
Intervals also seem to serve mental benefits as well. By having frequent rest periods inserted in between the high intensity bouts it will be easier to generate a total net level of energy output. There are literally an endless number of different interval structures that can be used. What works best for you will depend on your current fitness level and experience. Obviously a beginner would not start out by performing all-out sprints and would instead start off on a lower intensity plan. Advanced trainees could safely push themselves to a much higher level.
