    omg last answer is sooo wrong... muscle does not weigh more than fat...

     

    its like saying what weights more? 1 pound of feathers or 1 pound of cement.... its both the same its jsut muscles are more dense therefore taking less space

      It is true that a pound is a pound, however, if you took a bag of fat and put the same size bag full of muscle next to it, the muscle would weigh more.  Hope this clears up the muscle weighing more than fat.

      Muscle definitely does weigh more than fat, if you use physics the equation is density= mass/ volume so if you're saying that muscle is more dense and the volumes of fat and muscle are equal.... then density equals mass (because the volumes are canceled out) so if muscle is more dense it is heavier!

      As previously stated by others, a pound is a pound...it doesn't matter if it is fat or muscle.  So, muscle doesn't weigh more than fat...it is simply less dense.  Therefore, if you have a pound of fat and a pound of muscle, the muscle would take up less space.  Which means, you would weigh the same...or more, but you would have lost inches.  Also, a pound of muscle burns 30-50 more calories a day.  Make sense?

      The answer you are refering to is correct your wrong. Muscle is heavier then fat. The reason fat makes you look so bad is because it has no shape its not lean and it is just a blob hanging around your body now muscle is lean and can be very heavey yet wont look that way because is has a slender shape to it. It sits very close to the bones doesn't push out or hang. You learn in school during any and all health and pe classes that muscle weighs more then fat.

      it's not like that, if you have the same volume of fat and muscles, muscles will weight more for sure, so when you have the same weight of muscle and fat, muscles will have far less volume for sure, caus it's more dense.

    Oh dear god, Bob, that's the most asanine thing I've ever seen.

     

    Which weighs more, feathers or bricks if they're not in equal quantities?

    Muscle most certainly weighs more than fat. 5 lbs of muscle does not weigh more than 5 lbs of fat, admittedly, but that's not what anyone's saying.

     

    Yes, people have found that they do tend to weigh more after a workout. Most of the explanations that I've found are water retention after a workout, and most say their weight is back to normal a few hours later.

      YOU WEIGH MORE AFTER A WORKOUT BECAUSE ,YOUR MUSCLES EXPAND TO COPE WITH THE EXTRA BLOOD FLOW. ALSO,EVEN THOUGH YOU ARE LOSING SOME FLUIDS DURING CARDIOVASCULAR ACTIVITY, YOU USUALLY ARE DRINKING TO REPLACE MORE THAN YOU  HAVE LOST . WITH MUSCLE EXPANSION AND INCREASED FLUID INTAKE YOU WILL WEIGH SEVERAL POUNDS MORE AFTER A WORKOUT. USUALLY THE EXTRA POUNDS GO AWAY IN A COUPLE OF HOURS.

      Actually muscle is denser than fat, just like bricks are denser than feathers. If you were to compress feathers down to their basic particles (basically flaten them so there is no air at all) and form them into the same shape and size as a brick then their weight would be the same. No matter actually weighs more than anything else it depends on how dense it is.

    why do i weigh more after exercise

     

    I have noticed a 2-3lb. weight gain after a non-sweaty workout.

    I didn't drink fluids or eat anything either.

    The only way I can rationalize this is to understand some basic physics. body weight is a number that reflects mass in relation to gravity. the only way to gain "weight" is to have increased your mass or gravity. I am no expert maybe someone out there is, but our bodies have gases that have specific gravities. and perhaps stimuating the muscles and body through exercise we alter the amounts and types of gases which translates into weight gain.  again  I am no expert but maybe someone could further elaborate.

    hope this helped more than it confused.

    When you exercise you are working and toning the muscles. Because the muscles will be growing because of the workout, even though it burns more fat muscle weighs more than fat. So by working out you will start off by weighing more before you start to weigh less. I would imagine that if you carry on doing exercise your weight will eventually start to drop once your muscles have reached their peak and stopped growing and continued burning fat.

      i ran across this because i wondered why i was heavier after workouts, one thing that came to mind was that the body creates lactic acid (not sure the correct spelling lol) and that begins to weigh you down and make your muscles tired, dunno how much its weighs by any means but wonder if that would contribute?

      I think that everyone has to understand that matter can not be created or destroyed.  The person talking about density of muscle was correct to point this out becuase we cant just suddenly weigh more becuase of excercise.  Where did the matter come from to make us weight more? The only explanation is the water that we drank.  I would guarantee that if you were to weigh yourself at the gym before and after an exercise with your water bottle in your hand you would find out that you would weigh the same or slightly less because your body has given off fluids and heat.

    I have notice the same thing and I think I have a answer. It is the oxygen in your system. People don't realize how heavy oxygen is. When you are exercising you are increasing the oxygen and carbon dioxide in your system (blood, lungs and tissue). This slowly gets released throughout the day as your body no longer needs them. Hence when you are exercising the body is banking the gases and your weight goes up. It is just a theory.

     

    As to some of the other comments: mucsle weight more than fat.

    It could also possibly be because after an intense workout, especially a workout that includes weights, the muscles swell. If you are a person that has just recently started working out your muscles might swell because they are not used to the wear and tear. Just a theory but, I think it makes plenty of sense.
