Cassey and I investigate the biomechanics of butts. What activates your butt muscles more, running or squatting? How effective are bridges as a butt workout? How much can we change the shape of our bodies with exercise?

Huge thanks to Dr. Rowley for having us invade his lab for the day! You can check him out on facebook here http://www.facebook.com/kmichaelrowley
