Bret Contreras, PhD, CSCS,*D. I am the Glute Guy. I've been obsessed with the glutes for over 2 decades. As a matter of fact, I created this whole Glute Niche. Most of my videos pertain to maximizing glute size and strength. However, I'm also very interested in strength training biomechanics and most topics in sports science. I'm an avid lifter (still setting PRs in my mid-40's and recently pulled 635 lbs beltless), personal trainer (I train the Glute Squad), author (3 books: Bodyweight Strength Training Anatomy, Strong Curves, and Glute Lab), published researcher (over 50 studies), and international speaker (over 70 conferences). I invented the barbell hip thrust in 2006 and have worked very hard to popularize it and it's numerous variants over the past 15 years. I'm the founder of Booty by Bret, BC Strength, Glute Lab, and Stronglifting.
