Nelson and Brick Girl, oxidising fat requires oxygen, because of a larger oxygen intake required, cardiovascular training will assist in burning fat.
As you become fitter, your resting pulse will decrease. This reflects a greater stroke volume of the heart, and means that your heart is pumping more blood with each beat. ie, it becomes more efficient.
The fact this thread has gone to five pages indicates the level of stupidity present on these boards.
I don't know if the two of you are trying to impress the rest of us or not with your cavalier approach, but you're both being pretty fucking irresponsible, particularly you Nelson.
Cardiovascular work is beneficial for both fat loss and overall heath and wellbeing. End of story.
