Burned 1644 calories with new Polar FT4

I wore my Polar FT7 for the first time today. The calories I burned we're much less than MFP especially for swimming. However I wore it for gardening today and it gave me over 600 calories..yeah!

You have to be very careful with those calorie estimates though. 1600 calories in 1:45. That would be an INTENSE workout. Runningworld.com determined you burn 0.63 x your weight calories per mile. For a 200 pound person to burn 1600 calories in 1:45 you would have to run 12.7 miles (a 200 pound person would burn ~125 calories a mile). To run 12.7 miles in 1:45 you would have to run a an 8:16 min mile pace for an 1:45. (the equivalent of about a 26 minute 5k pace for 1:45). Obviously.. if you are lighter than 200 pounds... you would have to run even faster than that 8:16 pace. You can get more info here:

Your calories seem a bit high. I use my polar all the time and I do 2 cardio classes in a row and usually only burn 1100-1200. 1 hour spin and 1 hour body attack (high intensity cardio) I go all out sweat dripping on the floor. My model has the chest strap and also a 'test' you need to do that basically calibrates it to your resting heart rate. Does yours have that and if so did you do the test?

my ft7 got delivered yesterday (i bought it of amazon uk) and used it for the first time this morning. i ran for an hour on the treadmill and it registered 823 calories burned. its pretty clore to mfp 765 calories burned. the polar ft7 keeps a log of 99 workouts so i'll see if my hour run is consistent at 823 calories burned.

try changing the battery in the strap.

I hit my first 1,000 calorie burn in the gym the other day. Felt great! ^_^

Congrats on your FT4 - love, love, love mine! It's amazing and so much fun to watch your heart rate and calories burned!!!! On weekends that I'm doing more than basic housework and mom stuff, I will wear it all day just to see what activities burn the most. The FT4 is really all I need. My only suggestion is to buy an extra strap so you can wash it more frequently. I follow the instructions for every 5 uses & rinse every time I wear it (everyday), but sometimes that feels gross to me... lol. Oh and like someone else said, I keep mine on heart rate, too, for fear of watching my cals burned will affect my workout! Watching you heart rate MAKES YOU want to do more! Good luck and enjoy!!

Actually the HRM was less than the tread mill estimate, the tread mill monitors HR and you enter details and weight.

I think it's more to do with being not that fit but also being an athlete when I was young.

My heart rate max for my age 45 should be 175 but I peaked at 195 and spent suite some time at 180 bpm, if I was fitter I could do the same exercise with 180 peak and 165 being the rate for a long period.

I was exhausted believe me.

But the over week I done cardio and weights and cardio weights. Left gym went home ordered a 2000+ calorie pizza and still lost a pound in weight the next morning.

I have only ever really trained intense, always pushing myself 90% of the time.

I want to lose weight for health reasons and I'd also like to enter The Spartian run the hardest 5k race in the world so they say.

You cant really draw conclusions about eating a pizza and losing a pound the next day. I do a lot of intense cycling. If i sweat hard.. it sometimes takes a day or two for my body to normalize the hydration levels. The big thing you have to be careful with is double counting calories. MFP already counts your basal metabolic calories. Nearly all the treadmill estimates and HRM estimates include your basal metabolic calories as part of their calorie burns. Since MFP already counts those calories, it will cause the calories to over count. Also.... many HRMs are notoriously inaccurate. As an example... I have a garmin gps/hrm bike computer that is infamous among the bike community for over counting calories by as much as double. One of the reasons for this is that more accurate methods of calculating calorie burns based on heart rates are patented by companies. Garmin cant use the more accurate equations without running in to legal problems, so they purposefully used a far worse method to avoid the problem.... I agree that as you get more fit.. obviously the numbers change. I've just personally found with my year and a half of being on MFP and measuring all my foods on a scale... ive managed to determine that MFP calorie estimates tend to be over the real calorie count by about 40-50%.

Perfect example.... I went biking for an hour and 10 minutes at over 20 miles per hour. MFP estimates it at 1600 calories (185 pound man). Thats just insane....

Then there is a more accurate calorie counter that serious bicyclists use at http://www.kreuzotter.de/english/espeed.htm . This one estimates my bike ride at about 854 when i enter in all of the values.

854 vs 1600 calories.... My love of pizza wants to believe the 1600 number but years of experience shows me that the 854 number is more realistic.
