I appreciate your inquiry and look forward to talking to you soon. I also commend you for taking the time to exercise daily. You should weigh no less than 144 lbs. You did not tell me how old you are, and I can not give you a diet, because I do not know your health history, and some other physical profile information. But what I do recommend for you is that you continue the cardiovascular exercise.
Many females trim several inches off their waist by doing short or long distance runs up hills.
If you live in town I can suggest a few places where hills-small and large abide. Muscles can't be 'reshaped' nor can wgh fat, sugary sweets, sodas, alcohol, and other 'empty' calorie foods. As far as other ways to trim your waist please keep in mind that you are thin, and tall, and your hips may appear to be larger than they really are. I hope that you can contact me and we can go into a little more detail. Great luck with your training.
