Here is another IT IS THIGH TIME exercise video. To slim down muscular thighs you need to strengthen the hamstrings and glutes to balance out the overworking quads and IT band. What is great about this exercise is that you can do it anywhere. You just need a pillow (a ball or towel) to place between your knees.
