Now, if you really want to speed up the process you can do wind sprints and stadiums. These are the two best cardio type exercises that will have your butt looking firm and shapely. This is how you do it. With wind sprints, you will sprint as fast as you can for 40 yards, then walk back to your original position, then repeat. As far as stadiums, you sprint up the stadiums, then walk down. Just repeat this. Do these two exercises on top of your whole body workouts at least three times per week and you will see your butt getting into super lean shape.
