I do not own a (accurate) HRM. Is there a way to calculate my heart rate by how long Its there to see how many calories are burned.
Confusing right?
The machines I use have those heart rate sensors where you place your hands on them and it tells you your heart rate. So I place my hands on them serveral times during my workout to check my heart rate and usually it is between 143-160. I work out for 35 minutes. So is there a way to figure out how many calories I'm burning without a monitor?

I hope this makes sense lol

    If you have a mobile phone you can download apps to track calories burned.
    Hope this helps!
    Good luck.

    I know there's a way, you just count your heartbeats per minute. Sorry, I don't know the exact way but I bet someone on this site does!!

    Here is a site, not sure how good it is but here you do anyway: http://www.triathlontrainingblog.com/calculators/calories-burned-calculator-based-on-average-heart-rate/

    but you need to know your VO2 max

    This site may be better but I believe this calc estimates a VO2max for you. give it a try: http://www.livestrong.com/article/78365-estimate-calories-burned-heart-rate/

    For females, derive the calories that you burned. This is given by the equation C = (0.4472 x H -- 0.05741 x W + 0.074 x A -- 20.4022) x T / 4.184.

    Assume that you're a 28-year-old female weighing 146 pounds. Your average heart rate during an exercise session that lasted 36 minutes was 138 bpm. You burned C = (0.4472 x 138 -- 0.05741 x 146 + 0.074 x 28 -- 20.4022) x 36 / 4.184 = 301 calories.

    what the hell is a VO2 max? lol

    here's a calculator to determine calories from heart rate. it's based on your average heart rate over the duration of your workout, so you might have to do a bit of guessing to get the average w/o a monitor.

    http://www.triathlontrainingblog.com/calculators/calories-burned-calculator-based-on-average-heart-rate/

    to calculate your beats per min, if you have a watch w/ a second hand, find your pulse and count the beats for 6 sec. multiply that number by 10 and you have your bpm.

    Doesn't your resting heart rate affect this as well (so that you have a standard "base')?

    It should I think this calculation takes it into account, but I'm not sure what the base lines person resting HR is, and not to mention you will have to back out the calories you would have burned had you not worked out, it you plan on entering into MFP and eating your exercise calories. as this would be total calorie burn not extra calories burned.

    Thanks for pointing that out (about total cal burn vs. extra cal burn) - don't know that I would have realized that.

    My guess is the "0.4472" constant for HR must factor in resting HR somehow.

    for an estimate go to this site and plug in your info and use 35 for VO2 max, this will just be an estimate but you can see how it compares to MFP's numbers.

    Sorry, I should have asked that in a different thread or through a "message".

    You (25yo, 119lbs) said you workout for 35 minutes with an average HR of 150.
    So plugging that into the equation:

    C = (0.4472 x 150 - 0.05741 x 119 + 0.074 x 25-- 20.4022) x 35 / 4.184 = 349 calories.

    LOL

    You can find a decent price HRM w/ a chest strap at walmart for 45.00. Been using it for 7 months now and no issues! =)
