Although many here may hate it (myself included), it can't be ignored completely!
My main question is: How many of you subscribe to the old way of fat burning cardio: low to moderate intensity for longer periods (30 minutes to an hour), vs. high intensity cardio for around 20 minutes?
We all know by now that both have ups and downs, so which do you think:
*is more effective for burning fat
*is more effective for strengthening your lungs
*have other general health benefits or negatives
