How about a personalized weightlifting belt? You can choose one in her favorite color and have her name embroidered on it. Another idea could be a set of resistance bands, to help her workout at home when she's unable to go to the gym. If she enjoys reading, a book on weightlifting techniques or nutrition for weightlifters could also be a great gift option.
Or you can get her a star map with the date when she gave birth to you.
