How do i get slender (not muscly) legs?

Sometimes it is just genetics, if your mom or dad has bulky legs then compare the yours with theirs...As long as you are not a long distance runner or sprinter or into long distance biking. Or gymnast or anything that put big demands on your legs...To keep them tone you should do some exercising. swim, light running, stretching, light weights with low repetition and only a few sets.
