That is very interesting.
I will have to dig up some of my old physiology and biomechanics texts to see if that info is there.
ok, just dug something up :
the density of fat weight is about 0.90g/cc
the density of fat free weight varies from about 1.2g/cc to as high as 3.0g/cc with an average assumed to be 1.10g/cc.
so there is a 0.2g/cc difference. I have no idea if that is a significant difference or not.
In reference to this:

| I should get that book from the library so I can quote from it in this thread. She does some sort of calculation, perhaps using pounds per square inch of both muscle and fat and the muscle is a bit heavier per square inch, but only marginally so--certainly not enough to blame a scale that won't budge on the fact that you're gaining heavier muscle tissue |
there has to be some other factor to account for not seeing the scale budge. Possibly an increase in bone density, since weight bearing activities do increase bone density, but I imagine that would be neglible. I do know that muscle stores glycogen(its storage form of carbs) and that to each gram of carb there are 3 grams of water attached to it. So that would make sense, when you add a pound of muscle, you add 3 pounds of water with it. Or therebouts since many things affect the water composition in our body.
