Pound for Pound...

A pound of muscle and a pound of fat are both exactly the same weight, ONE pound. Muscle has a higher density than fat, so a pound of muscle takes up a lot less space than a pound of fat. It is similar to comparing cement to cotton candy. One would need buckets of cotton candy to equal one pound where as with cement it would only take a cup or two. As a result, some individuals who are performing an effective resistance training regimen might see a reduction in inches but not such a drastic decline in body weight. They are transforming their bodies through the reduction of body fat percentage and the increase there lean muscle mass, which in turn means they are “taking up less space”
