How does skin accomodate for increased muscle size or fat storage?

Wozza291: How does skin accomodate for increased muscle size or fat storage?
If you increase muscle size or get fatter does the skin just stretch or is more skin created? If it stretches, say you went from skinny to big and muscular, would the skin be in danger of just snapping?

skin under constant tension, produces new skin cells.

it does have a large capacity to stretch and reform, but really overweight people who then lose weight, often have lots of excess skin.

i know a bodybuilder with stretch marks on his chest. his muscles grew quicker than his skin i guess

You can produce more skin as needed. If the skin is stretched too quickly it does indeed snap, resulting in scar tissue. We call these stretch marks.
