Ah, that is the misunderstanding.

Muscle profiles are channels, so you modify them by scoping the channel
and then modifying the curve inside the channel/graph editor.

As you change the curves inside the channel editor, you'll see your
muscle's shape change to match it.

The additional profiles just allow you to have extra control over the
shape of the muscle.

Hope this helps!
