If I am weight training, doing a ton of resistance work, etc.. I will be getting nicely toned muscles *under* a layer (or 12 layers) of fat... So as fat loss happens, then those muscles will be visible?
I've met people who have lost a bunch of weight then say "Now, I need to tone it up". If you are doing a lot of weight training and working on toning the muscle groups while you lose weight, you will lose the weight and look toned?

My calves are awesome and sculpted too, and my butt "perks" visibly when I tighten up my gluteal muscles.
