there is a big difference between
fat calories and general
calories. When you exercise with an elevated
heart rate, you are burning a lot of
calories ... which includes
fat and other types of
calories, like protein. THis is not good if you are also trying to build some muscle definition. That's why, most exercise machines have a setting for "fat burning" ... which is not strenous exercise ... it's more like a light jog. However, you do not burn as many
calories .. so there is a trade-off.
There is a compromise ...
HIIT (High Intensity Interval Training). As the name implies you are doing intervals of high intensity ... ie. jog for 5 minutes, sprint for 1 ... or, what i like to do, jog for 45 sec, sprint for 15. This is supposed to be a good balance of burning a lot of
fat calories without burning too much protein.
