Let's say I'm doing "Aerobics: High Impact" (I do Banish Fat, Boost Metabolism with Jillian Michaels) according to Spark the 45 minute video only burns 250 cals. Does Spark calculate that I'm only working at moderate intensity?
When I do that video I keep my heart rate at 80-85%. I don't do the "strength circuits" and instead do high intensity cardio moves like running on spot, high knees, jump rope, butt kicks, jumping jacks with kickouts and I push really hard the entire video going much quicker and harder than the instructor and demonstrators. It just seems that 250 cals is awfully low for that workout.
Same goes for Coach Nicole's Jump Rope video. I use it mainly to count my intervals but I jog at a moderate pace during rest intervals and push to my maximum heart rate during active intervals.
When I punch my average heart rate into a calories burned by avg heart rate calculator it gives me a much higher number. Not even just a little bit higher, we're talking 2x as high. I'm quite conditioned and can keep my heart rate up in the maximum zone for an entire 50-60 minute workout.
What is the same is when I walk, I usually have an average heart rate of 75-80 bpm and when I put walking at 2.5 mph I get the same calorie burn from Spark as I do from a calories burned based on avg heart rate calculator for the same duration.
So does Spark assume I am only working at moderate intensity for most exercises?
It's important for me to figure out because I've already experienced health problems (amenorrhea), low RHR (42 bpm), bordering on below normal blood pressure, and sudden binge eating/sleep eating even sticking to the upper range of calories Spark gave me (1200-1550 cals, I was averaging between 1400-1500 cals when I started experiencing these symptoms) because it had me assumed as "sedentary". Now with the new feature to enter your activity level, I've corrected that but I'm still worried that I'm burning more than Spark assumes I am. I lose weight way too quickly any time I try to follow Spark's suggested calorie range for me. For example, in my healthy BMI I was losing 2-3 lbs/week eating 1400-1500 cals. I'm just completely confused now on how many calories I should be eating.

Take your focus off the Marshmallow. www.leangains.com/2010/01/marshmallo
"Toning" is marketing muscles to women who are afraid if they pick up a barbell, they'll leave the gym looking like She-Hulk. It doesn't happen, what does happen is you get results. Lifting Barbie weights does nothing but waste time.
