Train your body evenly.
Looking around at the gym, I have noticed that most women spend more time at the machines that target the inner thighs, hips or butt. It seems that other body parts are not as important to them. Unfortunately, this approach is not a good idea. Trying to "spot lose", by just training the body parts that bother you, can cause muscle imbalances. This can lead to injury, poor posture, and a worse physique. Just as you train equally on your left and right sides, train equally in the front and the back to see the best results and to keep your body trim, healthy, and strong.
Good luck and as always, let me know if you have any questions.
