What should i do to shed weight from your butt?

Can't spot reduce.: There is no such thing as spot fat loss. You would need to lose weight in general & a certain proportion of that will be butt fat. Exercises that will work your buttocks include: lunges, squats, dumbbell squats, stepups, toe taps, plie, squats with kickbacks, hip extensions, one legged dead-lifts and the gamut of aerobic exercises (running, swimming, bicycling, kickboxing, walking).
