Doing an excellent job, Rosie. I completely agree with everything you're saying.
i do cardio everyday. 30min or more of walking..works for me
@ Rosie: I searched through your article trying to dispute the sources of the information you gathered. I failed, I will look more into this idea that Lance Norton has of burning glycogen stores during cardio. Apparently the goal is to trick the body into burning fat during rest periods. Lance is his own experiment and his shreddedness leads me to find him a credible source.
I can personally attest to the effects of high intensity cardio - pretty much next to NONE of my cardio is done at less than 80-85% of my maximum heart rate and I have NO issues when I want fat loss (which blows that "target fat burning zone" out of the water). Besides, who wants to spend 40-60 minutes or more doing cardio when they can get more effective results in ~20 minutes?!
Yes, DOCTOR LAYNE NORTON is a very credible source.
