Choosing a combination of moderate- and high- intensity cardio exercises will typically yield the best results.  This will be especially true if your goal is weight loss.  Include activities that are moderate-intensity and fall into your fat-burning zone about half of the time.  Activities may include: slower jogging, biking or swimming.  However, this will be different for everyone. Also choose some cardio activities that fall into a high-intensity range.  Although this falls out of your fat-burning zone, you burn more calories overall and increase your body's cardiovascular fitness levels.  In general, you burn more calories at the zone above your fat-burning zone (the aerobic/cardio zone) which is generally at a higher intensity.  However, total calories burned also depends on the duration of a workout and it may be easier to do a longer work out in the fat-burning zone as it's at a lower intensity. Also, aim to reach 150 minutes of moderate-intensity cardio activity each week at a minimum. Incorporating strength or resistance training into your weekly exercise schedule is important.  It helps build and tone muscle in addition to increasing your metabolism. Weight training is critical for fat loss. It is crucial to keep and gain muscle while losing fat mass.  Include strength training at least two days a week for a minimum of 20 minutes.  Strength training activities include:  weight lifting, isometric exercises (like push-ups or pull-ups) and Pilates. If you're interested in your fat-burning zone and how you can best utilize that information, meeting with a personal trainer or coach may be a good option.  They can help you find your fat-burning zone and help design an appropriate workout that utilizes that information.  Talk to your trainer or coach about your goals.  Is it weight loss?  Increasing your muscle mass?  This will help them tailor their program to meet your needs. Also ask how you can utilize your fat-burning zone to your best advantage.
