Is this possible? 911 calorie burn in 80 minutes?

    possible yes, but if you HRM said that then you probably didn't burn that many, HRM's are not accurate when it comes to strength training. The calculation used assumes a certain oxygen uptake that only occurs during cardio. So while you were lifting your HR does go up but your HR assumes it is going up due to the same physiological factors that cause it to go up during steady state cardio, which it does not, and will over estimate your burn for everything other than cardio.

    I don't want to hijack the thread - and I absolutely believe you on this - but I'm wondering the most accurate way to account for your burn when strength training?

    That is a great question. I am not 100% sure, but I would probably want to use a bodybugg or fitbit to get a better estimate than an HRM.

    whats VO2?

    volume of oxygen uptake. V02Max is the maximum capacity of an individual's body to transport and use oxygen during exercise. Also known as: maximal oxygen consumption, maximal oxygen uptake, peak oxygen uptake or maximal aerobic capacity (not anaerobic (sprinting and strength training)

    I still don't buy this. It might be scientific, but just like BMI calculations, it's all speculation. I guarantee I burn more with my weight training in 45 minutes than someone jogging on a treadmill for 45. I don't see how it can possibly be valid if someone that weight trains super sets all exercises, works the entire body, and never takes a break.

    In that case you may burn more than your HRM says, but you HRM will not be correct.
    More, I'll give you that. This concept always baffles me. All in all it seems that there is no way to possibly know.....just don't over eat I guess.

    I might be wrong but I think the fitbit is just a glorified pedometer type thing. Think you might mean bodymedia fit?

    I used to burn about 900 calories playing racquetball in about that length of time according to my HRM. Not sure I could last that long anymore though.

    Awesome information guys. Thanks for sharing!!!

    I'll try to get my self a bodybugg but it's tough getting one shipped to Canada.

    It does make sense that the HRM would overestimate resistance training a little bit. I guess I'll just try to count 2/3 of what the HRM shows me and also try to enter my stats into it before I get my bodybugg.

    Thanks a lot guys!!!

    Appreciate the info!!!

    Have a great day!!!

    No you HRM is telling you to CALL 911 cause you are getting so swole!

    Haha joking aside, i burnt around 2,000 calories yesterday rock climbing for 2 hours so 900 cal in 80 is very possible.

    I am SUPER jealous! I wish I could go do that! Did you boulder, or what?

    Nah i was top roping, was actually at the gym for about 4 hours, but since i don't count belaying my buddy as exercise, i just put 2hrs.

    If that is what your HRM monitor said and if it is working properly - ABSOLUTELY!

    Yes, its possible. I went jogging for 80min one day and burned 1142 calories.. I'm a plodder so I logged it as race walking NOT jogging cause i DONT just MFP.That gave me 842 calories:-)..That was still good enough for me. I dont have a HRM, I cant afford one. I rely completely on MFP and other sites to estimate my burns

    HA! I have a fitbit but don't wear it for strength training because it's inaccurate for anything other than walking/running.

    Guess I'll just stick to the estimates :)

    Ugh, I have been using my Polar FT4 to log all of my personal training sessions which start with intense cardio. I had no idea it is not accurate for strength training:cry: No wonder my weight loss has stalled, I eat back those calories and I'm probably overeating at this point.

    Can someone explain in baby terms why it is not accurate for strength training? Today my hair was soaking wet and sweat was flying off my face from my PT session, which is much more than what happens when I am doing cardio.

    ^^Here is some info you may want to read up on. If you notice...HRM are failrly accurate but they do not "over estimate"..infact they under estimate.. No matter what the exertion done to sustain a elevated heart rate....the heart has been exercised either by cardio or via strength training.

    stuck at work for New Years eve. No one around and I work graveyard hours so I went outside to jog the hills and stairs near my workplace. I wanted to see how long it would take me to burn 2012 calories

    I tried to be cute and have it read 2012 calories burned but my stupid heart wouldn't stop beating to have it read that.

    You said you checked it when you got home... did you still have it on during the ride home??? Your HR will still be elevated but I wouldn't count that as part of my "exercise"

    I have been using my HRM foe a while. I find I burn about 10 cal per min on average. And more if I'm going hard.
