Lunges: Focus on lunges, squats, and dead lifts. The elliptical and stair climber also targets that area. Gradually add more weight. You can lookup exercises on youtube as demonstrated by a certified personal trainer or speak to one at your local health club. Generally it takes 6-12 months to start seeing changes. Try to exercise 4-5 days/week.

Butt exercises: Squats, lunges (including backward, side &d curtsy lunges), step ups, hip thrusts, Bridge (including marching & single leg bridge), quad hip extension, donkey kicks, single leg deadlift, fire hydrant, split squats, frog pumps & fire hydrants can all be used to work on butt muscles.
