How do I know how many calories I'm burning?

[denisio]

If I want to lose a certain amount of weight, I can track how many calories I'm taking in on a daily basis without a problem. However, I don't know how many calories I should be taking in because I don't know how many I'm burning.

Can anybody help me with this?

You can invest in a good heart rate monitor and this will calculate the number of calories burned while you are working out like I do because I hate using machines and take a lot of classes at the gym and with the help of this can calculate the number of calories burnt. You can also look up the following website and get an idea of approximately how many calories you would burn while doing a certain activity.
