Supertraining

Hi Tim

I know it may seem pedantic but can people not say muscle weighs more
than fat. Since the statement should be that for the same volume of
fat and muscle the muscle would weigh more - namely muscle is more
dense. I say this because 2kg of fat weighs more than 1kg of muscle,
so the comparison with similar volumes or similar body sizes is
important.
