Muscle weight vs. fat weight

We've all been told that muscle weighs more than fat, right? That would be like saying a pound of feathers weighs less than a pound of lead. Here is a link to a picture that shows that muscle doesn't weigh less than fat but it is more compact than fat, therefore, taking up less room in our bodies. http://www.blueprintsolution.com/store/fitcommerce/fat_vs_muscle_2.jpg I found this interesting and thought I would share.

Gross!
