What are some of the best exercises for legs and thighs to lose inches and shred??

I have been trainin with women who is pear shaped. Her trouble area and most unconditioned part of her body is legs & thighs. Our workouts are focused on leg/butt. We do alot of cicuits w stregthening, cardio & now plymetrics for her lower body. I train her at her home 2x a week. She lost 5 lbs (goal is 10)and lots of inches everywhere except for thighs (only 1 inch). Its been 3 months.
