Being such a prominent and well recognized body part, it’s easy to forget the fact that your butt performs very important muscular functions. There are 3 main muscles in each of your buttocks: Gluteus Maximus, Gluteus Medius and Gluteus Minimus! These are the muscles that are going to get us to the top! No joke, power is in the butt! The bigger the better! So get on a bike! or get doing some squats and then roll around on the floor in pain after.
