Here is the result from Polar F6 doing Burn It Up. Keep in mind the result I got will and may be different from others. That is because of difference in each person's Heart Rate, Body Condition (age, height, fitness level, weight, etc). So, with those in mind, I am:

Female - 35 years - 5' 2" - 105 lbs - small built
consider myself fit enough, I haven't been doing BIU at least for 1 month
Starting HR when sitting down, motionless: 75-78

Total workout: 60min
Total calories burned:  285 cal, with estimated 45% burn fom Fat
Heart Rate: 164 max, 124 avg
In-Zone HR: 129-147, for 21min 14sec.

Now this may not seem much to you. (.."what??? 1 hour of muscle aching workout for only less than 300cal??...") :p

My logic to answer this is: SI6 incorpporates a lot of resistance training in the workout. Not merely cardio. You noticed how sore your muscles are from doing stand up crunches, squats, lunges, etc. And a lot of sets are slow pace. That forces the muscles to work harder. As other resistance training, you also reap the post-workout benefit.


I compared this with my Turbo Jam/Punch Kick & Jam workout. Fast pace high energy cardio. This one does have a resistance training in the end but not as much as SI6.
Here is the result:

Total workout time: 49min
Total calories: 317 cal, 35% burn from Fat
Heart rate: 171 (92%) max , 147 (79%) avg
In-Zone HR: 129-147 for 10min 44sec.

So in shorter time while I do burn more calories, my in-zone is only half the time of doing BIU, burn from fat is less, max HR is higher. This is due to different in activity. With Turbo Jam, it is more about cardio, heart rate is pumped up most of the time, with short intervals of breaks. And while achieving higher calories burn, it is less in building muscles.
Not saying one is better than other, it is really 2 different workouts with different objectives.

Suffice to say, I am happy I finally able to measure my workout :) YAY for HRM ^_^
