You don't mention what you are eating or how clean your food intake is...
I truly believe that food makes the biggest difference, you've heard of the saying"
"Abs are made in the kitchen."
Well. so are legs, arms and every part of the body... I think that if your food intake is not super perfect that you won't get rid of the fat very easily...Specially in those difficult spots../
I too have alot of fat on my thighs, specially upper thigh ... I also think it's because it's the last place for the fat to go it will also be the most difficult... Everyone has a weak spot for some it's tummy... for us it's thighs...
I too used to do those inner/outer thigh machines until someone advised me not too because it makes your legs look bigger because of the fat on top of the muscle on the inner thigh

... arg!!! Some days the harder you try the harder it is!!
Keep at it eventually it will go away!
Hope this helps... I'm sure the other ladies will have some great suggestions too....
