Everyone likes to refer to their butt with some kind of different name. Booty, rear, tush, cheeks, fanny, keister, you name it. We could go on and on. But (no pun intended), the correct anatomical term is Gluteus Maximus. Now here's the kicker -- we have three Gluteus's! The Gluteus Maximus, the Gluteus Medius, and the Gluteus Minimus. So, essentially we have three butts. Nice, huh? Well, let me explain a little about each one, so you will understand what I mean.
The Gluteus Maximus is the largest and the main mover of our hip region. It is also most superficial, meaning closest to the skin. It helps us walk, squat and get up from the couch.
Next comes the Gluteus Medius and Minimus. These two muscles lay underneath the Maximus, with the Minimus being on the bottom (the deepest of the three muscles). So, basically on each side of your rear, you have a stack of gluteals. The picture will help you see what I mean. The Medius and Minimus work together and share the same actions. They both stabilize the body when you stand on one leg, aide in walking, and act as a helper to the Maximus.
I hope you enjoyed the first Factoid Friday! Please keep checking back for more! Now, go exercise those glutes! :)
