Yes - this is part of the process! Think of a balloon filled as much as possible with air or water. It's firm and hard. Let some of the water out, and it becomes more pliable. Let out more, and it becomes softer still, and jiggly! The difference is that your body will start adjusting as you build muscles and as your skin starts shrinking. (How much your skin will shrink depends on many factors.) It sounds like you're on the right track and making progress!
