Can You Really 'Tone' Your Body?

"I really need to get toned up." I wish I had a dollar for every time I heard that. You've probably said it a million times...heck, I've said and I even know better. What I'm talking about is the idea of 'toning' your body. Most people think it means getting more definition and firmer muscles by doing high reps with light weight. But what you may not know is that this idea of toning is only a myth.
