Hey man, sorry to keep doing this to ya (the check's in the mail)...but in regards to my last post on Low/High intensity cardio... my final question to you is:
If I am running 45-60 minutes straight (heart rate averaging 165, is this still considered low intensity(burning fat only, but maintaining muscle?) I just don't want to burn the muscle I am developing in the gym...but if I can continue to run my heart rate up at that speed and burn fat ONLY, I will do that. What do you think?

If that is your true bpm, that is probably not low intensity. Make sure that you are going by your pulse, not a cardio machine. Low intensity for me is walking on a treadmill at level 15 incline at 2.6 - 3.0 mph. It's a slow pace, but still makes you work and keeps pulse significantly and constantly elevated. Keep in mind for cardiovascular health, going high intensity is good sometimes (a la HIIT for added fat burning).

Check out any of the "target heart rate" calculators online and work toward the lower end of your range. In the "fat burning zone" as most of them call it.
