Firstly let's look at the anatomy of the Glutes ⬇️
Gluteus maximus - A superficial muscle that is not only the largest muscle within the glutes (which gives your bum its overall shape), but also the largest muscle in the human body. The gluteus maximus performs extension, abduction and external rotation at the hips.
Gluteus medius - A deeper smaller muscle which lies underneath the gluteus maximus. The gluteus medius provides hip abduction, and can assist in hip extension and external rotation.
