The internet is great...for getting conflicting information. I need to cut body fat without losing too much muscle mass. My question is, which is best? Low intensity or high intensity?
Is the "fat-burning zone" reality or myth? I find it hard to believe that a heart rate of 115 - 125 is best as my resting heart rate is 85 - 90 (I'm 41 btw). My normal cardio puts me at 80 - 85%. Right now I'm 5'10" and 220-ish. I'm very solid, but do have a bit of a belly.
All opinions are welcome.
