Creating Workouts Based on Your Target Heart Rate Zone

The key with cardio, whether you're trying to lose body fat or stay fit, is variety. Choosing different activities at varying lengths and intensities will help ensure that you work your body at all levels of endurance. Here are some ways you can use your THR zone to create a variety of workouts.

1.Interval training. With interval training, you'll alternate between low intensity exercise (like walking or jogging) and high intensity (sprinting or hill climbs) to burn calories and build endurance. Your intervals can be of any length, e.g. 3 minutes easy, 1 minute hard. Use your heart rate monitor along with Perceived Exertion to make sure you're working hard enough during your work sets.

2. Endurance training. Building endurance requires longer time spent exercising. For that reason, these workouts might be longer and slower, e.g. 45 minutes at a heart rate that matches level 4-6.

3. Burning calories. To burn the most calories, you want to work at a higher intensity. As a result, these workouts might be shorter and more intense than endurance training. For these workouts, you want to keep your heart rate at a level 6-8 throughout your workout.

Practice using your heart rate monitor during different workouts to get a sense of how hard you're working and make sure you're training effectively. If you don't have a heart rate monitor, move on to the next step for more ways to monitor your exercise intensity.
