sorry KMA not really. take a muscle out of the body put it on a lab bench. it is just muscle..it can't change shape, can't get flabby, can't get more defined. what's the difference between this and in the body...is that the body has fat. higher the bodyfat the more it covers the muscle making it less defined.
