A nicely modelled bottom is the goal of many women who sign up for the gym. What does it take to have a firm and muscular bottom à la Jennifer Lopez? There are many workout plans to make the buttocks bigger. These are exercises that engage three muscles: the gluteus maximus muscle, the gluteus medius muscle and the gluteus minimus muscle. We start with two workouts of min. 30 minutes per week. After two weeks, we add exercises with dumbbells to the set of exercises. It is important to increase the loads over time.
