Female Training: Toning Issues

Question:

I have a client who had a baby seven months ago. She's 5'9" and weighs 125 pounds. In the past, she always did aerobics and circuit training for "toning." She's been training with me for about 10 weeks now. We alternate tubing days with kickboxing, five days a week. When she's not working with me, she runs on the treadmill. On tubing days (resistance workouts), she will run after class also. That being said, she runs every day and does resistance training two to three times a week. She has a soft look to her. She's trim everywhere, but she has no distinct muscle on her body. Her midsection is her biggest problem area. She's particularly soft here and actually carries a little tube.

Do you think it's her eating habits (i.e., too many carbs)? She tells me she takes in a lot of protein - for her height and level of cardio, what should she be taking in? Do you think somehow with all the cardio she does, she is burning up the muscle she should have created by now? She's no weakling either. She can punch pretty hard and land a nice kick. Any advice you could offer is appreciated.
