How many calories am I burning?


Quote  |  Reply

So I do Turbo Jam 5 days per week for 40 minutes. Today I used my new heart rate monitor and it said my average heart rate was 162 during my exercise and that I burned 730 calories in 42 minutes.

However, when I go to other websites and put in my stats I get anywhere from 350 to 800 calories were burned. Help! Should I just trust my heart monitor? It goes off my heart rate and weight but NOT gender. Thanks! Oh, my stats are 5'7 female 26 years old, 179lbs. What do you think my calorie burn is?

Heart rate monitors are not perfect machines, but they are by far the most reliable way to determine your energy output. close to 730 is probably correct, if your heart rate was really averaging 162 for those 42 minutes.

 

Thats a pretty high heartrate to sustain.. I run long distance, and quite quickly, and my "average" is normally lower, 150-160 area. I cant imagine Turbo Jam would burn more calories then a flat out run, so maybe you didnt wet the chest strap enough (providing your HRM is similar in structure to mine)

 

One time after a hike, my heart rate monitor said I had burned 1100 calories, mt average heart rate was 167, and my max heart rate was 202!! I knew this counldnt be right, and it wasnt. Your PRE (perceived rate of exhertion) should be able to tell you how accurate your heart rate monitor is.

Thanks for the info. My resting heart rate is about 85 or 90 tho because I work in the medical field and am constantly taking it along w my Blood Pressure. My max heart rate was 180 and min heart rate was 88 for that specific workout. I did wet the sensors but probably not enough...

 It helps to wet the two little snaps on the belt where you hook up the encoder as well!! I started getting WAY more accurate readings when I did this. Also, make sure you arent wearing any body lotion!

Your numbers may be correct though. I have a very low resting heart rate because of the amount of cardio exercise I get, so you never know! Its highly individual. I would try it once again and if you get a similar reading, then your HRM is reading true.

The beachbody programs like Insanity and Turbo Jam focus a ton on HIIT. The calories burned using these programs definitely is larger than just running.

I have a pretty low resting heart rate, between 50 and 58 BPM, but as soon as I do anything strenuous it jacks up superhigh superfast.  My most difficult workouts are steady state workouts because I have to monitor and be totally conscious of my exertion to keep below 160.  If I run, forget it... I'll usually max out around 185-190.  I've rowed competitively in the past, and on an erg test or race (when I was going all out) I would hit 208.  Definitely not the most comfortable, but so far my heart hasn't exploded, and the resulting nausea from BPM > 196 keeps me in check.  Basically, my point is that you're right, it IS highly individual, and a HR reading of 165 on such a workout video could be spot on.

 Im not talking about running on flat ground. I do hill interval trail/pace running for distances of 13+ km... I have done a TON of classes that focus on HITT and nothing gets my heart rate going like running.
