what is meant with muscles wheigh heavier than fat`?

everybody says it yet i would say it's the opposite. a 15" arm athletic shape weighs less than a 15" arm fat shape doesnt it? im curious :woo:

Muscle is denser than fat; it has more mass (weight) per unit volume, therefore a 15" muscular arm would (discounting bone etc) weigh more than a 15" fat arm. That's a bad example though.

1kg of muscle weighs exactly the same as 1kg of fat; however 10 cubic centimetres of muscle weighs more than 10 cubic centimetres of fat.

So there.

No its true, muscle is heavier because it has a higher density, where density is expressed in kg/dm^3

ok men then maybe i should go check my eyes or something =P when i look for example at s0lid with 15" arms and only 158lbs then i can hardly believe that a fatazz with 15" arms same bones etc as s0lid has less weight on his arms but when it's scientific proven then it's proven.

however one last question. the muscle density isnt always the same isnt it?

thays because the fat person will have fat all over like stomach will be much larger then a fit persons abbs for example, as for diffrent density of muscles they are simular although can vary a bit depending on water content in the cells.

Also, you can't flex fat. So if you talk about a 15" arm with no fat, but only muscle, you shouldn't imagine a flexed muscular arm, but a relaxed one. If you were to flex that arm, it would be much bigger.
