What's the best exercise to make your inner thighs smaller and more toned???
Well, there are different ways for different people.
I think lunges help the best because you are forced to use your leg muscels to pull you up and down. If you think lunges are too easy try doing them with your hands straight out with weights.
But my best recomendation would be to go swimming.
