Bret Contreras

Contreras took a doctorate in sports science at Auckland University of Technology, studying gluteal activation with electromyography, and is known professionally as the Glute Guy. He developed the hip thrust as a loaded exercise and published the research behind it, which is unusual for someone whose main audience is on social media. Bodyweight Strength Training Anatomy and Strong Curves apply it. He sells training programmes and certifications, which is the business the books support, and he is careful about separating what the evidence shows from what he believes.
