Benefits
Your glutes are made of 3 different muscles : gluteus maximus, medius & minimus so it is important that you include exercises in your routine which target every area! Generally speaking we divide the glutes into 2 areas as it is easier to remember: bottom and upper area
Compound exercises like deadlifts, good mornings, squats, lunges etc they all tend to target the bottom part of your glutes, while abduction exercises target the upper half. Of course note that when you do an exercise you will always tend to target the full glutes as muscles are connected to each other but you will tend to engage one part more than the other depending on which exercise you are doing!
