What I've said is completely factual. Muscles have carbohydrate structures that allow more energy stores, aside from fat. When muscle degrades? what does it become? fat. Also, what grows around muscles? Fat. Muscle development adds to bone strength and bone restructure, thicker and healthier bones.

Where do you think muscles get their energy for immediate needs? It's not thin air. It's fat, and structures that have carbohydrate reserves. Athletes that have a less fat, and more muscle are marathon runners, body builder competitors, and boxers trying to lose weight. During the off season, their muscles look healthier, because that is muscle with fat. Sprint runners have more fat, and still have lean muscle, because that fat and carbohydrate structures are needed for their muscles to run fast for the distances they run. Women's bodies have muscle, and while the butt is mostly muscle, the curves overlap and intertwine with muscle is fat, that the muscle needs or uses when needed.

And fat is also useful for hormones balance.

"Exercise improves the makeup of bone structure," is 100% correct. Bones are living fluid structures, and they develop to match the muscle that they support. For instance someone who has arm muscles, develops a thicker cross section of bone there.
