as you’ve noticed, I’m wearing a heart rate monitor in our Slim & Strong workouts. My heart rate is very high during our classes, averaging 160-170 beats per minute (bpm) and a high of 190. I usually burn about 550-575 calories. I’m 5’2 and weigh 136 lbs. I have heard of the magical ‘fat burning zone’, which is a much lower heart rate. I usually spend about 10% of class in that zone, if that. It seems to me that you burn more calories at higher intensity and with a higher heart rate, so I don’t really get this ‘fat burning zone’ idea. Is this something I should be concerned about? is there a good way to monitor my heart rate to keep the intensity of my workouts effective once Slim & Strong boot camp ends in a week?
