Hi! I would have to say that the best way to remedy this is cardio and lower body strength training. The cardio helps burn the fat that's there and the strength to help develop the muscles. Lunges and Squats will be best.
Also you will need to change up your routine ever 4-6 weeks. Your body will get used to the cardio you do & the strength exercises.
The food is actually at least 50% of the battle. I know you are thin elsewhere, but it does make a difference. It has taken me a looooong time to realize this! But it really makes a huge difference to cut back on the food.
Good luck and keep track of your measurements once every 3-4 weeks so you can track your progress! Can't wait to hear more!
