My thighs are my problem spot. I work really hard doing lunges and squats but no matter what, they never seem to get as toned as I would like. I have since accepted them for what they are and appreciate that they help me walk, but man, why won't they tone-up? We all have that one part of our body that, no matter how much cardio and resistance training we do, just does not want to tone up. So what is your problem area?
