what about the intensity? and at what point do you start burning muscle?
what about the intensity? and at what point do you start burning muscle?
ok so, 70% of your HR is the border line.. above that will be anaerobic hence muscle and fat as your energy sources and below that (aerobic), aka low intensity cardiovascular exercise will use fat as its primary energy source. with that being said, you shoudl do 20-30 minites of low intensity AFTER resistance training when muscle glycogen has been depleted out of the muscles and fat. check out my thread "some physiology that yous hould know" in the diet forum to expand your knowledge on bodily processes
your making it seem like its 50% fat 50% muscle which it is not...
DEPENDING on the intensity, it will use muscle or fat as a primary energy source
low intensity will use fat as a primary and losing muscle has all to do with your diet anyway. im doing low intensity fat bruning cardio and ive lost fat and gained muscle
