im just wondering i want to start running but i want to know how many calories i burn are heart rate monitors u wear on ur wrist pretty accurate like i dont care if its not right on the dot but will it give me a least a close estimate like within a 100 calories also how does a heart rate monitor calculate the calories u burn say i am just sitting and watching tv will it calculate the calories i burn just sitting please help me im so confused

Hi, I have a stationary bicycle. 1 hour of exercise says I burned 150 calories. My heart monitor watch which has my weight, age with a belt around my chest says I burned 850 calories. The internet sites quote anywhere from 800-1200 calories per hour for a fixed bike.
As I am counting my daily calorie intake, could you please help me understand if I should use 150 or 850 as an input for exercise.
THANKS!

Everthing I’ve seen so far has the strap that goes around your chest. I don’t like that it seems restrictive to breathing, and I read that it shifts around when they kick too hard off the wall. But I also want to improve my laptimes. Are there any Heart-Rate monitors (HRMs) that count calories that you can wear on your wrist only? Any alternatives to the chest strap?

I have a Polar heart rate monitor that I use for cycling. When I ride or do spin class, the calories burned on the watch is different than the calories burned when I upload the information to the desktop software. For example, a spin class may show 1,000 calories burned on the watch, but when I upload the data it shows 600 calories burned. Why is it different?

I noticed at a store today that they are selling heart rate monitor watches. To get a heart rate reading, you have to put your fingers on these two little contacts on top of the watch.
The watch says it also can keep track of how many calories you burn. But do those actually work? If I’m doing weight training, I’m not exactly able to hold my fingers on my other wrist for the entire time. So How does it actually keep track of calories burned?
Does anyone have one of these? Do they work well?
