Here are several tips to increase your calorie burn with your elliptical trainer: - Build in Intervals
Most elliptical trainers offer incline and or tension that you can increase or decrease while workout out. Try building in 30 second incline intervals every couple of minutes to your workout. This will not only push your body further and burn more calories during your workout - but it can also elevate your calorie burn for up to 24 hours after your workout.
      Use Upper Body Arms: Many ellipticals offer you upper body arm   bars that you can use to build your arms muscles into your workout.   More muscles worked = more calories burned. If there are no upper   body arms, grab a couple of 2 - 5 pounds handweights and swing your   arms while striding. - Take Advantage of the Forward and Backward   Directions - Using more muscles (and one you may not have used   before) also ups your calorie burn, even after your workout.   So take advantage of the fact that most ellipticals allow you   to go forward and backward. Switch up your routine every few minutes   to up your calorie burn. - Break up your Workout…Experts are now   telling us that 2 mini-workouts may even be better than 1 long   workout as far as calories...
