How Much does Muscle Weigh?

That depends on how many pounds of muscles you have. Your question may arise from the saying that muscle weighs more than fat. This is not exactly true. One pound of muscle weighs exactly the same as one pound of fat. Two people of the same height and have different percentages of body fat, the person with more muscle may actually weigh more. However, because muscle is more compact than fat, the heavier more muscular person may actually appear to be thinner.
