When your working out, intensity is key to reaching your goals. Especially when the subject is weight loss. You want your heart rate to be between 55-85 % of your maximum heart rate. To calculate this you need to know your max heart rate, which is 220-age= maximum heart rate, then that number multiplies by .55 all the way to .85. Keep your heart rate in that matrix for 30 minutes, and you’ll be burning fat!
