Ride a bicycle for about half an hour…It focuses on burning fat in the thigh area

At he gym: Leg presses=Quads

                Dumbbell lunges both short and long=Quads and hamstrings
                Squats with either dumbbel or barbell behind your back=Quads
                Thugh abductor and addcutor machine= to tighten your inner and 
                outer thighs.
                 Leg extensions=Your lying on your front and your curling your leg up and unto your butt.

Yeah I hope it’s helpful (:-)

Okay this worked for my aunt, walk on your butt across the floor, it sound totally stupid but it have her a perfect but and it worked her hamstrings too. also another at home work out is hanging on to a chair and raising one leg back to a horizontal angel really pulls the butt and the outer thighs, and you can do it to the sides as well. hope I was of some help

Deep lunges with weights…

do squats…that not only tightened up my butt, but also my legs. do some sit ups, and v-sits. and also eat right.
