Want to grow your glutes and shrink your waistline? Well, here is a 13 minute workout to get you on track. This routine combines 3 ab/waist workouts and 2 glute building moves. For the glute workouts you can add a 35 pound dumbbell for more resistance to stimulate growth. Ideally, it's best to do this routine three to four times a week. However, don't forget to adjust your diet base on your fitness goals.
